ifi Micro iDSD BL (Black) review​
-expatinjapan​
 ​
Thank you to ifi for sending me the ifi Micro iDSD BL to try out as it made its way to Hawaiibadboy of Head-fi who also resides in Japan. I dont usually do loaners these days as its a lot of work writing a review, taking pictures etc etc. But I have had a steady communication with ifi for a while now and that is also important in my books. Plus pre Head pie i won an ifi ipurifier in one of their Head-fi contests. So time to give back.
Unfortunately even though they did afford me ample time to try out the ifi Micro iDSD BL due to it being over the New year and into heavy work load January and organizing my house for a new in coming baby I did not get to put it through its paces as much as would have liked to.
 
The ifi Micro iDSD BL is packed with many functions, an audio swiss knife If you will, it contains so many options it truly initially stopped me in my tracks for a while as I tried to figure out where to begin.
 
But begin I did....

`Intelligent In/Out SPDIF Digital Optical/Coax
 
Digital Audio Players (DAP) and home SPDIF sources are abound. Flexibility remains key and the micro iDSD BL retains the intelligent SPDIF in/out socket for optical/coax signals. So for those who wish to upgrade their DAP, simple use it as a transport and feed the micro iDSD Black Label.` - via ifi website.
 ​
 
 
 
 
 ​
So many mind boggling options.​
 
 ​
Sound
 
I tried the ifi Micro iDSD BL with a simple ipod set up, via SPDIF to the iBasso DX200, my basic home set up and also out of my Macbook.
 
In all the configurations the ifi proved to be a high performer, not surprising considering how long they have been around and the many products that ifi have made.
 
The ifi iDSD BL is definitely a souped up version than its earlier sibling with better specs overall.
 
Its sound is quite neutral, detail orientated and overall quite transparent. The sound stage is wide, separation between instruments is of a high quality, the reproduction of the source material is very honest and accurate.
 
If one is looking for a unit on the warm sounding side, this isnt it, and thankfully so.
 
One also has the options of the many many switches to toggle between for larger headphones or sensitive IEMs, to increase/decrease power or gain.
 
 
 ​
 ​
  Value
 
At $US549  the ifi Micro iDSD BL (Black) is a good purchase.
 
Its multiple inputs and outputs make it a versatile unit that can suit a users many audio needs.
It certainly has a decent price /performance ratio.
 
As with all ifi products it is well designed and manufactured.
 
It can be considered more transportable than portable, and is more ideal for an addition to home set up.
 
whether in conjunction with other ifi products, and existing home system or by itself with a set of active speakers.
 
 
 
 
As seen at a Tokyo Headphone show.​
 
 
Overall
 
The ifi Micro iDSD BL is a solid and well made unit that goes for a sensible price.
 
Its many inputs and outputs make it a unit that can be used with a variety of products.
 
Whilst the size certainly puts in more in the transportable area than as a possible portable device, I would see most users preferring to utilize the ifi Micro iDSD BL as a part of home system or independently with a set of active speakers, connected to a computer or simply fed with a source and enjoyed at a desk via a set of earphones or headphones.
 
The sound of the ifi Micro iDSD BL model is one of clarity, great details, authentic reproduction of the source materials, medium to wide sound stage, full bodied sound in the lows and mids without become flabby, dark or boomy, the highs are soft and extended.
 
It certainly packs enough power to drive most headphones with ease. And has enough subtle settings to also make it suitable for sensitive IEMs.
 
A wide variety of setting switches means that the user can also customize it to their preferred sound signature.
 
To conclude the ifi Micro iDSD Black is a versatile product that does neutral very well, but also by way of various switches and settings allows the users to customize their sonic experience.
It plays well with large headphones and also more sensitive IEMs.
Its compatibility and many inputs and outputs make it a versatile future proof machine.
 
Plus it looks smexy.

Thank you to ifi for loaning me the ifi Micro iDSD Black.​

What was your impression of the 3D effect? Does it create a 'being there' experience? Or is it simply a little reverb and filter?

Pros: Versatility, power, accessories, quality XBass if that is what you are after
Cons: size for portable use, sound quality is very good, but not exceptional for the price
 First of all I would like to say thank you to iFi for choosing me as one of the lucky tester of their new iFi Micro iDSD Black Label in the UK section of their worldwide loaner program. I have had a lot of fun during this week and I really enjoyed playing with the Black Label and comparing it to my Chord Mojo.
 I chose this title for my review, as the Mojo is one of the most popular competition to the Micro iDSD BL due to its similar purpose and price point, and probably many potential buyer will be looking for comparisons of this two DAC/amps. This review reflects my personal, subjective opinion. Ears, headphones, sound signature preferences widely vary, which can lead to different results. Reading many reviews however can give the reader a direction to go, and test the chosen audio equipment to see if that really is what they want. This review is not the ultimate objective truth, but one honest and subjective opinion from an audio enthusiast.

 IMG_20170208_083747945_BURST001.jpg

Background:

 I am in this hobby for 8-10 years, and I simply love to listen to music in high quality and just relax and get lost in the tunes after a busy day. I am not a professional sound engineer, like many reviewers here on Head-Fi. I am not very interested in different graphs and measurements as my ears can tell me whether I like the sound of a DAC/amp/headphone or not. I am into detailed and clear bass that has authority, but does not suppress other frequencies. I like clean and slightly forward mids with lifelike vocals and smooth, laid back but not rolled of or lacking treble. I can’t stand harshness, sibilance and plastic sound which I define as the opposite of a real, lifelike, and natural sound presentation.
 I mostly listen to ambient, downtempo, electronica, but I also like trip-hop, some vocal centric music, and occasionally even classical music.
 Since on Head-Fi there are already a lot of detailed reviews about the iDSD BL with measurements and technical details, I decided to focus on comparing the BL to my Chord Mojo, and do it in a more subjective way.
 
IMG_20170211_135509006.jpg

Equipment used:

 For this review I mainly used my beloved AudiQuest NightHawk headphone, but also tried my (new) Cardas A8, and Sennheiser IE80 (just sold) IEMs. I have been using my Chord Mojo almost every day, since I purchased it a year ago.
 My source is a Dell Latitude E7440 laptop with Foobar2000, AudioQuest Jitterbug and I use bitperfect mode, mainly with FLAC files and some DSD.
Let’s see then, whether the iDSD BL has got enough to offer me to dethrone the Mojo.
 
IMG_20170211_103531403.jpg
 
Accessories, built quality:

The iDSD BL comes in a nice box, with tons of accessories. I can’t imagine anyone complaining about the number of connection cables, adapters and other accessories. The cables and different sockets on the iDSD BL offer endless possibilities to connect almost anything and everything to iFi’s latest flagship DAC/amp. There are also rubber bands and rubber sheet for portable use, not to mention the nice carrying pouch.
 At this point I will echo the opinion of many other reviewers: I just can’t see the BL as a portable device due to its size. When connected to a smartphone it is almost the size of a real brick. I often find even Mojo too bulky for portable use. On a positive note, the BL is easily transportable, which means you can just put it in your bag and take HQ audio with you on your holidays.
 No complaints regarding the built quality, the BL is indeed a very well-built piece of equipment.

IMG_20170211_094651171.jpg
 
About some of the switches and sockets on the iDSD BL:

 This is the area where the iDSD BL has a clear advantage over Mojo. It is much more versatile. You literally can connect it to anything and everything, while Mojo was mainly designed to be a DAC/amp ‘on the go’ used with smartphones.
The iDSD BL can find a place in many areas, from studios to speaker systems, home audio systems and you can also use it on the go. That being said I mainly use my Mojo as a desktop DAC, but I admit it might not be the most ideal device for that.
 
 At first I did not really understand why iFi chose a female USB A socket as digital input. It is very uncommon, since most of the aftermarket USB cables are Micro B male to USB A male. If somebody wants to upgrade the supplied iFi USB cable, will have hard time to find one. (It is debatable whether upgrading USB cables make sense or not, but there always will be customers, who want to do that.)  On the other hand I can understand iFi’s decision, as the Micro USB B connections can often be weak and loose, while the USB A socket gives a much safer and tighter fit, especially when you have the female version, where the bigger half of the USB plug’s head is basically ‘swallowed in’ by the device.
I find the extra USB socket on the side of the BL a very useful addition, as you can use it to charge other electronics on the go.

IMG_20170208_083611420_HDR.jpg
 
Volume knob:

 I have to say from the perspective of comfort I prefer the (software controlled) analogue volume knob of the iDSD BL to Mojo’s digital pebbles. It is just simply more comfortable to turn a knob than tapping on buttons. However choosing the right volume level to match the impedance of your headphones or IEMs can be a bit tricky with the iDSD BL. iFi says the volume knob should be set at 12 o’clock or above to achieve optimal performance. The reason for this is, because on lower volume levels (below 10 o’clock) there is audible channel imbalance on iFi’s DAC/amp. According to iFi, this compromise had to be made in order to have the better sound quality of the analogue volume knob.
 With the ‘power mode’ switch (and ‘IEMatch’ switch if you use IEMs) you need to find the right settings first, to be able to turn the volume knob to 12 o’clock without any issues. In my opinion for some users this will be slightly inconvenient, and some other users who do not necessarily read the user’s manual just won’t understand why they experience channel imbalance in their headphones when the volume knob on the iDSD BL is below 10 o’clock.

Power mode:

This switch will be in normal position with higher impedance headphones, eco mode with IEMs and low impedance headphones, and in turbo mode with speakers I guess, as I can hardly imagine anyone keeping the switch in turbo mode even with the highest impedance headphones, it has so much power!

Polarity and filter:

To me these switches did not make any difference.

3D toggle switch:

 I kept the 3D effect switched off. To me it did not make the sound better, but on the contrary. There is a slight treble elevation, that I would rather call treble boost not 3D. The soundstage also becomes a little wider, and the sound a bit airier, but to me this effect is too artificial, with no benefits.

XBass toggle switch:

 One of my very first impressions with the BL’s sound was that the bass is quite present, even without the XBass effect turned on. Switching the XBass toggle on is like turning up a subwoofer on your head. (Although it is a very well implemented subwoofer, it does not kill the rest of the frequencies.) I can’t imagine anyone using the XBass effect continuously. Occasionally with some bass heavy electronic music it can be real fun for a few minutes, as you can imagine yourself being in a concert venue or club, where the bass from the subwoofers just shake all the internal organs of the audience. At times it can be fun, but impossible to live like this long term.
I kept both the Xbass and 3D effects switched off for the rest of my time with the iDSD BL.

iFi Micro iCAN 1st gen. vs. iFi iDSD Black Label:

 The iDSD BL is not the first iFi product in my hands. I owned a Micro iCan 1st gen. and a Nano iCan at some point of my life. (Unfortunately I have no experience with the iDSD 1st gen.)
Compared to these iFi amplifiers, I can see the physical and hear the sound quality improvements, even though I have to rely on my memory with this. Sorting out the illogical switching directions of the 3D and XBass toggles of the older units is a very good thing in my opinion, but I have to add, I miss the two step Xbass settings from the Micro iCan.
  The iDSD BL compared to the Micro iCAN 1st gen. sounds much more natural, and smoother. The BL’s sound is very smooth, ensuring long fatigueless listening sessions. In my opinion it is a great direction to go from previous iFi house sound.

Sound quality:

 Since I have been using Mojo almost every day for a year, I know its sound very well. When I turned the iDSD BL on the first time, I instantly noticed the nice and smooth sound with quite a weighty bass, but I found it more two dimensional and less exciting compared to Mojo. Almost like the warmth was just a little too much, creating a very thin, velvety veil compared to Mojo’s immediately obvious clarity and dynamic punch. The bass being strong and present on the BL does not help with this sensation. Please do not misunderstand what I am saying, the iDSD BL does have a very nice sound, but in direct comparison to Chord Mojo, these differences are present to my ears. It is not night and day, but to me it is obvious enough. Do not forget, I am using the NightHawk, which is already a warm headphone with a relatively good amount of bass. (Same true for the Cardas A8.) Perhaps bright and treble-centric open back headphones like for example most of Beyer’s line up benefit more from the iDSD BL’s warm and more bass-centric sound.
 The soundstage on the iDSD BL is slightly wider than it is on the Mojo, however Mojo’s exceptional depth gives the sound a real 3D feeling, which makes the 3D effect on the iDSD BL even more unnecessary. Instruments and voices are better separated on Mojo, and they are slightly more detailed with a better contour.
 This picture appeared in my mind while I was A/B testing the two DACs: listening to the iDSD BL is like sitting in a comfy plush chair in a cinema with a nice speaker system watching a concert of your favourite band, while listening to the Mojo is more like being in a small jazz club, listening to live music. The latter means a more intimate and more realistic sound, but both have the right to exist.
 These differences mostly pop up in direct A/B comparison. When I only listen to the iDSD BL for a couple of hours, it is also very enjoyable.

IMG_20170211_103120045.jpg
 
Let me go into a bit more details regarding the frequency regions:
 
Treble:

 The treble on the iDSD BL is very smooth and non-fatiguing. Despite the relaxed high frequencies everything that happens in this region is clearly audible. No disturbing high pitch noises, even percussion never comes through as harsh or piercing. (I believe, brighter headphones with the 3D knob turned on can sound harsh, but this is a very unlikely scenario. I suggest to leave that knob alone anyway.) The iDSD’s treble is an absolutely fine treble. Nothing is missing, but also nothing is shining through. Mojo in comparison has a slightly more detailed, more dynamic treble. Instruments sound clearer, more present (and more lifelike) to my ears.

Mids:

 This is where the difference is the most obvious in favour of the Mojo. In direct comparison mids sound slightly recessed on the BL and more forward on the Mojo. Mojo is a ‘mid-heaven’. While on the BL mids are there and fine again, Mojo just wins this part by quite a long mile, being absolutely realistic and lifelike. On vocal centric music the difference should be obvious to most ears. It feels like good recording vs live singing. Probably the exceptional depth on Mojo also helps the voices to sound more realistic.

Bass:
 
 I find this region the most interesting. I have already mentioned one of my very first impressions with the BL was the somewhat weighty bass. Do not misunderstand what I am trying to say, the bass on the iDSD is not overwhelming, and it does not bother the mids, neither the treble, it just always feels more present compared to the Mojo. (Remember, it is with the Xbass effect being turned off.) This velvety smooth and good bodied bass gives a real base to the sound on the iDSD BL. It is not bothering, but this sensation of bass presence is always there. I do like warm and smooth sound, but when I do critical listening (like now), I would not mind to have a little less of these two brilliant sound characteristics. At casual listening, when the headphones are simply on your head and you do some reading or anything else, this extra warmth and smoothness can actually be very useful, saving you from listening fatigue, and ensuring a comfortable long listening time. For my personal taste Chord has found a bit better balance between clarity and smoothness, and I find the iDSD BL leaning just a little bit too much to the warmer side here, and I mostly hold the bass quantity responsible for this. (I still consider the BL to be a huge improvement over the Micro iCan 1st gen.’s brighter and not very realistic sound.)

IMG_20170211_103830411.jpg
 
 I find Mojo to be more true to recordings. Mojo also has a stronger dynamic punch, and the bass becomes big and thumping only, when the recording is calling for it. If we wanted to oversimplify things, we could say the BL has bigger bass quantity in general, but the Mojo’s bass is better defined and higher quality. After coming to the conclusion, that the iDSD BL has got a bit more bass quantity in general, I was very much surprised, that with some sub-bass heavy music tracks like the ‘Creeper’ and ‘Animal’ from the band called ‘The Acid’ the sub-bass notes were more powerful on the Mojo, while the BL has run out of that big bass juice at the lowest notes, and became slightly rolled off in this sub bass region. After the strong bass presence on the BL this small difference in the bottom frequencies was quite surprising to me.

IMG_20170208_083716801.jpg
 
The differences that have been highlighted between the two DACs in this review are not very huge differences by any means. Both the iDSD BL and the Mojo are great DAC/amps, and you can’t really go wrong with any of them. In this tight A/B comparison however I have to give the edge to Mojo on pure sound quality (not versatility!), but I know, probably some people will prefer the iDSD BL’s smoothness and bass centric sound to Mojo’s precision and dynamism, and there is nothing wrong with that.
 The Mojo to my ears has a slightly more refined sound with better depth which results in a space, where you can experience lifelike music with plenty of fabulous dynamics. The iDSD BL provides a very nice and very smooth listening experience. In head to head comparison, the Mojo sounds more exciting to me, so for me the choice is clear. The iDSD BL is a very nice product, its versatility is impressive, and it truly has a top performer sound. At the end of the day, diversity is what makes this world beautiful.
 For me however the nice and smooth, good quality music listening experience what the iDSD BL offers just can’t beat the excitement and beauty of Mojo’s natural realism. Of course, as always, Your Miles May Vary.

Punchy bass and warmer. Hmm this might just be what I need to perfectly pair the Campfire Audio Andromeda, which has a fairly bright/treble-rich signature by default and does not benefit from extra brightness from the sources. Also, if it's a bit on the bass heavy side, it might pair it well for the exact same reasons. The Andro is balanced on bass but could use more punch with a few tracks that are mastered in a thin signature.

@rickyleelee, each to their own, I guess.
@beowulf yes, that seems to be a good pairing. Give it a go. :wink:

Excellent review and I find it to reflect my findings. While I very much prefer the IDSD with my Sennheisers and Fostex TH900 (they perfectly complement one another) I do prefer the Mojo with the Nighthawk which you used for this review.

iFi iDSD Black Label
 
Hey guys, this is my quick review of the ifi idsd Black Label. The unit itself is courtesy of ifi, and is a loner unit which I am borrowing for seven days as part of a world wide review tour. Besides getting to audition the unit at our home for seven days with our own gear, there are no other incentives or hidden agendas on my part. This is my honest opinion and my opinion only.
 
Thank you to Laurence @ ifi for giving me the opportunity of auditioning this unit.
 
 
Unboxing:
IMG_9314.jpgIMG_9315.jpgIMG_9339.jpgIMG_9336.jpgIMG_9337.jpg
 
Upon opening the box I was greeted with the unit itself. Taking the unit out of the box, it feels like a well made piece of gear. There are two switches on the front, one is for the XBass+ and one for the 3D+ features. The switches feel sturdy and have a nice firm click to them when flicking them up or down. Up engages the given feature, down is the normal off position. 
 
The volume knob has a good size for the device, and sticks out enough out of the way of the 3D+ switch which is positioned right next to the volume knob. One thing to note here is that the volume indicator on the knob itself is just a small slit and is black on an already black knob so I really couldn't tell most of the time were the volume was at. I would have prefered for the tiny slit to be painted in orange like the rest of the printing on the device for a better visual aid.
 
Also on the front of the device we find a 6.3MM jack and a 3.5MM jack. The 6.3MM jack is the headphone output, and the 3.5MM jack is actually an input! I was surprised at first since I was expecting both would be headphone outputs to accommodate for both 6.3mm and 3.5mm headphones without a need for an adapter, non the less I don't find it to be lacking either way. The addition of this input makes this versatile device even more diverse as it can be used strictly as a headphone amplifier too!

IMG_9319.jpg
 
 
Moving on to the back of the device we find a pair of RCA outs and a very clever combo SPDIF Coaxial/Optical Input and Output. Also on the back of the device we find the USB input. Again, I find it quite clever for iFi to have the USB input implemented this way. It is essentially a male USB jack that has been recessed in the chassis of the unit. I found it extremely sturdy and very spacious. It easily accommodated for a CCK from my ipod touch and it also fitted my Android USB otg cable without of course, the need for any extra adapters in both instances.
IMG_9320.jpg
 
Flipping the idsd BL on its side we find three small recessed switches that are very well implemented as far as being easily accessible. Easy to switch yet also out of the way enough that I don't think they'll be accidentally engaged when carrying the unit in your hand. Turning the unit on it's belly we find some more orange printing indicating, for example, what these three switches on the side of the unit are for. 
 
One switch is for the Power Mode, one for the Polarity, and one for the Digital Filters. 
There are three positions on the Power Mode switch. Eco, Normal and Turbo.  
Eco = for high-sensitivity IEMs
Normal = for medium-sensitivity headphones
Turbo = for the most-demanding headphones

The Polarity switch has either "+" or "-"

From iFi: "Adjustable signal polarity of music playback. For a digital signal source only (ie. not for an analogue signal via the 3.5mm input.)"

In all honesty I have not read up much on this and I tried it a couple of times and found there was no noticeable change to the sound.
 
The Digital Filters switch also has three positions and are as follows: Bit-Perfect, Minimum Phase, and Standard. I believe iFi recommends "Bit Perfect" for PCM, so thats what I used my short time with the iDSD BL since I did not use any DSD or DXD files.
IMG_9323.jpg
 
 
Also on the bottom of the unit we find two more switches. One switch is towards the front of the unit and it's iFi's very own iEMatch(TM). This switch is for further use in tweaking your headphone output for ultra sensitive iems especially. There are three positions on the switch; Off, High sensitivity and Ultra Sensitivity.
 
Towards the back of the unit we find a two position switch indicating Preamplifier and Direct mode. Direct mode is used as a fixed RCA output that bypasses pretty much everything else on the unit and goes straight to your power amp, headphone amp, etc.
 
Preamplifier: (direct quote from ifi)
the iDSD functions as a DAC/preamplifier. The volume control is now enabled for the RCA line output and when used in conjunction with the Power Mode offers gain of: 


  Eco = 0 dB
  Normal/Turbo = 9dB

Last but not least on this incredibly versatile unit we find a female USB socket on the remaining side of the unit. This USB port is labeled SmartPower Charging on the belly of the unit. It is used to charge small devices like your smartphone, ipod or other digital transport you might be using with your iDSD BL.

Turning on the unit.
The volume knob is also used to power on the unit. I used the provided blue USB cable and plugged in to my laptop. Plugged in my headphones, turned on my Tidal desktop app, aaaannnd nothing! No music came out. I opened up my Windows playback devices and did not see the idsd BL on the listed devices so I figured I needed some drivers. A quick google search lead me to the idsd BL product page and on the bottom of the page found the Downloads tab which led me to the Windows drivers. After a quick download and setup I was ready to go...
 
Listening impressions.

I did most of my listening the first few days with my Grado PS1000. The Grados are not considered particularly hard to drive but I have found them to be a bit picky of headphone amps and even DACS. I've owned the PS1000 for over two years now and it has been overall my favorite headphone up to date. I would say it is a very colored headphone compared to all other TOTL headphones I've tried, but it is also very exciting for me. Listening through these cans is always a pleasure for me as the music is always very lively and transparent. The midbass has a very noticeable boost and the highs are very airy. Voices and guitars are excellent imo.
 
Listening to a few tracks the idsd BL sounds balanced to me and very similar to what I'm used to hearing straight out of the Mojo. The Ps1000 sounds properly driven, the details that I'm used to hearing are all there, there is no added sibilance which is great because I've came across a couple of DACs and amps that didn't play well with the Ps1000. It does not sounds too analitical, has nice warmth and the mids sound proper, not thin. I do feel like it might not be as involving as the Mojo.
 
I decided to compare it against the Mojo since I feel like these two are direct competitors and are around the same price range. For my home setup I use the Mojo feeding my headphone amp so I was curious to see how the iDSD BL would compare.
 
Micro iDSD BL as a Dac vs Chord Mojo.
 
I connected both the Mojo and the BL to my laptop. Both are then hooked up to the Schiit SYS and then the Schiit SYS to my MAD Ead+ HD headphone amp. I listen with my Grado PS1000. All tracks were from the Tidal desktop app. All are lossless FLAC files and also lots of new "MASTER" files which are at 24/96kHz and a few files at 24/88kHz. In the Tidal settings I check "Force volume" and "Use Exclusive Mode" for both the Mojo and the BL. 
 
Switching between the two DACS is as easy as opening the settings in Tidal, picking either dac and the pressing down the button on the SYS. It is important to note that in this direct mode, the Mojo sounds a tad louder so I did compensate the volume on the amp when switching to the idsd BL. Volume matching was done by ear and I did as best as I could.
 
Setting on the Mojo itself: I held down both volume buttons when powering on to set the volume to a standard output level for typical line-out use.
 
Setting on the BL: I tried both from battery power mode and USB powered. Output switch set on "Direct".
 
What I hear with this setup going back and forth was that the BL sounds a bit more laid back than the Mojo. I felt that overall it fell a bit short in comparison. The Mojo simply feels like it has more PRESENCE. The ifi BL tends to have a softer sound. The bass hits a tad softer, vocals are a tiny bit further (also softer), the Mojo sounds like it has a blacker background, the music sounds like it has better attack and it sounds clearer than the BL. There was more enjoyment out of the Mojo since I caught myself more than few times bobbing my head, singing along and tapping my feet to the music when listening was switched to the Mojo.
 
Now for the sake of being a bit more thorough I'd thought I try this same setup but this time I switched the idsd BL Output switch to pre-amplifier instead of direct mode. I then proceded to get the volume on my amp as closely matched as possible between the Chord Mojo's "standard output level" and the volume wheel on the idsd BL to match it. Power mode on the idsd BL was on "normal" btw. 
 
What I now heard was a lot more closer than before, in fact I'm having a hell of a time trying to nitpick and find any differences between these two. I hesitate to say the Mojo is a tiny bit more nuanced than the BL, but I can't reliably tell a difference so I'll just leave it at that.
 
As a dac/amp vs Chord Mojo:
 
Same setup as above but without the Schiit SYS and my MAD Ear+ in the audio chain. Volume matching was by ear and once again I did as best I could with these two. Using the Grado PS1000 here's what I found:
 
I spent quite a bit of time comparing side by side really trying to pick at something to reliably point out but in all honesty I would not be able to tell these two apart in a blind test with my headphones. Any differences that might exist are so small that I don't feel comfortable even pointing out. Again this is my experience with a given set of headphones. One thing to note though, on extended listening sessions between the two, I noticed that I found the Mojo more engaging and musical. The iDSD BL while apparently not lacking any behind the Mojo still fell a bit short for me as far as listening pleasure goes.
 
Listening with XBass+ and 3D+:
 
I must say that I did enjoy both the 3D+ and XBass+ features. With the Ps1000 the 3D+ switch makes the treble more airy and expansive. Highs are boosted very tastefully with these headphones and I did find it useful in many tracks but not always. Both these features are well implemented and are good to have imo. I also had great success with the XBass+ and 3D+ on a pair of Ortofon eq-5 iems that I borrowed from a friend of mine. Again the 3D+ makes the treble sound airy and the sound stage more expansive and the bass boost did just that boosting the low end on this iem to a much more favorable level.
 
Electrical interference: 
 
One thing that I almost forgot to mention was that I found the iDSD BL did really well on my desk  right next to my cell phone and also my office phone. The reason I noticed this is because I always have to set my cellphone aside to a different location away from my gear and I also end up unplugging the office phone from the wall wart because of electrical interference.
 
Due to the short review period with the unit time did not permit me to further test the unit more in depth. I did try the unit as a DAC/pre-amp with my power amp and speakers and I can say that the couple of tracks I heard sounded very well in this setup. I also wanted to compare the amp section od the idsd BL versus my RSA Intruder but only manage to squeeze in a few tracks. I thought the idsd definitely held it's own but the intruder still has a more mature sound and is a step ahead of the amp in the idsd bl.
 
In conclusion: 
 
Well that about does it for my impressions of the Micro iDSD Black Label. In my opinion ifi have themselves a winner in this device and I would have no reservations recommending this to anyone who is in the market for a DAC/AMP combo in this price range and a bit beyond really, whether it be desktop, transportable or portable this thing is very good and certainly up there with the Chord Mojo on a short list of what to buy under $1000. Great bang for the buck!

Headphoneus Supremus
Pros: clarity, power, versatility, build quality
Cons: crowded front panel, questionable filters
It is with great pleasure that I can say that I have been selected to take part in the iFi Micro iDSD Black Label listening tour. My thanks to Lawrence from iFi for helping to organize the USA East leg of the tour. What this means, is that I have 1 week to listen to & evaluate the ifi Micro iDSD Black Label, which is a DAC utilizing a dual core Burr-Brown DSD512/PCM768/2xDXD chip and headphone amplifier. Although I am very grateful to be able to participate in this tour, I receive no compensation other than the joy of listening in the comfort of my own home, and the following review is my honest opinion. This is my 1st ever review of a DAC/amp, so please bear with me as I try to hit all the pertinent points.
 
 
I’ll start with a little about myself. I’m pushing 50 and have less than perfect hearing (50 is pushing back). I’ve been a music lover for as long as I can remember, and I learned to listen a little more critically during the few years I sold audio equipment (and the more I listen, the more I learn). My fascination/infatuation with headphones began about 4 years ago, and has only gotten stronger. I’ve only recently taken a more serious look at the hardware end of the audio equation, and I’m enjoying the journey. I've never had the opportunity to hear the original iDSD, so I'm particularly glad to spend some time with the Black Label. The majority of my listening was done listening to FLAC, WAV & various MP3s with my Shanling M2, Fiio x3 (1st gen.), Samsung Galaxy S7, or through my HP all in one PC as a source for the iDSD BL. My tastes are fairly eclectic, but my listening centered on classic rock, folk, jazz, classical and various genres of EDM.
 
 
First, let’s get a couple of ergonomic niggles out of the way. When using the iDSD BL as an amp only, the front panel gets awfully crowded, (especially if you’re using a ¼” to 1/8”) adapter making it difficult to adjust the volume or activate/deactivate the Xbass+ or 3D+. Perhaps changing these 2 filters to the right side would alleviate this issue, especially since I didn’t find myself using them a whole lot. Occasionally, I found the selectors on the bottom of the unit to change positions during normal movement of the unit from one place to another. In fact, at one point one of the plastic knobs fell off of the selector switch it was attached to (giving me a slight heart attack since I don’t own the unit)
IMG_0592.jpg
 
Fortunately I found and reattached it without further incident. A set of raised feet would likely prevent this from happening.  I also found the volume pot can use a bit more resistance. It was too easy to turn, and although I give kudos for the orange font on the bottom, a volume indicator line that’s not black on black would be much more useful (and greatly appreciated).
 
 
The iDSD BL came with a generous amount of accessories. There are 2 of the usual rubber bands for stacking, RCA cables for preamplifier use, a storage pouch, USB A to USB B cable, 3.5mm (male x male, for use with the line in) adapter, 3.5mm x 6.35mm adapter (the front panel has a ¼” headphone out only), an optical by RCA adapter, USB A (female to male) adapter, and a rubber mat. There’s really not much more I could say I’d like to see included.
 
 
There are so many things this little beast can do I feel a bit overwhelmed trying to cover it all. On the front panel from left to right, you have a ¼” headphone input jack, Xbass+ control (on/off), 3.5mm audio input jack,  “3D+” control (a filter said to create a larger soundstage, also on/off), and the volume control dial.
IMG_0566.jpg
 
The right side is bare, except a USB Type 'A' Female connection for charging other devices.
IMG_0568.jpg
 
Around the rear there is an “Intelligent In/Out SPDIF Digital Optical/Coax” connection that automatically configures to Coaxial or Optical use, a left & right female RCA output, and a USB Type 'A' male digital input.
IMG_0590.jpg
 
Moving along to the left side, there is one portion of the gain control (Eco/Normal/Turbo), a polarity switch (+/-) and filter control (Bit Perfect/Minimum Phase/Standard).
IMG_0591.jpg
 
On the bottom of the unit, there are markings to identify all the controls on the sides and back (orange on black is very legible, thank you!)
as well as the other portion of the gain control called IE Match (Off/High Sensitivity/Ultra Sensitivity) and control for the rear RCA outs (Preamplifier/Direct).As I said there is a lot the iDSD BL can do, and given I was only able to spend a week with it, I’ll concentrate on what I did use.
IMG_0574.jpg
 
There are five power output modes, Eco, Normal and Turbo, High Sensitivity, Ultra Sensitivity. Their website states that the micro iDSD BL is able to have the power and gain dialed-in to”perfectly suit all headphones”. In truth, everything from my 64 Audio U6 to my Sennheiser HD600, the ifi easily delivered whatever power was needed. It had copious amounts of power when called for, never needing to go over 11:00 on Normal gain with the HD600, and more often closer to 9:00. I am not the best judge of hiss due to persistent (and tenacious) tinnitus, however without music playing using my U6 on Eco gain, there was no discernible noise whatsoever (YMMV). Obviously, when using the High Sensitivity or Ultra Sensitivity settings, there would be even less noise. I’ll note that I’m not sure what “type” of amp the iDSD BL utilizes, but it never felt more than warm to the touch, even during heavy usage.
 
 
 I’m a firm believer that amplifiers for the most part (at least amps of the solid state variety) should be the proverbial “Wire with Gain” in that they shouldn’t impart much “color” onto the sound. That being said, in reality I think there is always some sonic coloration passed along when creating an audio chain and an amplifier is no different. I’ll admit that there is the possibility that I haven’t acquired the skill of breaking the sonic influence into bass/mids/treble/soundstage, but I believe that these influences are much more subtle than that. I would go so far as to call an amp full, thin, warm etc. but not much more, especially without having equipment to back up my claims. I find the amp section of the IDSD to fall on the warm side of neutral without sounding thick or muddy in any way. When comparing to other amps I have on hand, my ALO National or the RHA Dacamp1 (On loan for a listening tour, comparing amp only here) I find there to be more similarities than differences. Because they are all so close in fidelity, without volume matching, it’d be impossible to comment on detail retrieval and the like, but the overall impression I had was that they are all warm-ish amps: everything I played sounded full bodied and satisfying.
IMG_0560.jpg
 
If you’re using a PC and you want to use the iDSD BL as a DAC, you need to download the driver from their website ( http://ifi-audio.com/micro-idsd-ifi-xmos-firmware/ ). If you’re a MAC lover, it is supposed to be plug-n-play, I believe. Downloading and installing the appropriate driver was more of a challenge than I expected (IOS users, this is your cue to laugh). Every time I downloaded the driver to install, it would literally disappear after a few seconds. It was there, and then it wasn’t. To say I was perplexed would be an understatement. I assumed that there must be an explanation, so I read a bit online until I came across one post noting that you may have to turn off your anti-virus. How a driver could look like malware is beyond my computer knowledge, but someone figured it out, and I’m glad they did. I turned off my Norton, and we were back in business. Once the driver was downloaded, and the  ifi took over DAC duties, the synergy of the DAC/amp combo became readily apparent.
Since the front panel does get crowded once the line in is being used, I mostly opted to use it through the Coaxial input or as a DAC/amp. The coax from my Fiio or Shanling sounded terrific, with plenty of detail and space, definitely a step up from the line out IMO. The iDSD BL is unwieldy, but is indeed portable enough to move from room to room, or to take with you for listening while writing in a coffee shop or other stationary activity. This was quite welcome if I didn’t feel like being tied to my computer to listen, or wanted to continue my listening session elsewhere if it was getting noisy. The iDSD BL did pair easily to my Samsung Galaxy S7, and though there was no faulting the sound quality, it was awkward at best given the size difference. Again, if being used while stationary, it wouldn’t be a big issue, but it’s not really a portable solution.
IMG_other_0586.jpg
 
 I do think most people will opt to use this primarily as a DAC/amp, either on a desktop, or portably with a laptop. If I were to do a blind test, I would be very hard pressed indeed to distinguish between the coax & the USB, at least with my current sources, and I think that’s a very good thing since I enjoyed the iDSD BL so much either way. Again, without a proper A/B test I don’t feel confident enough to give a definitive answer as to which one is better, but I am inclined to say the DAC in the iDSD BL would be the superior choice. It definitely has a synergy with the amp section, and benefited from being fed higher bitrate files without being too unforgiving of MP3s. I could (and did) listen to this for hours, enjoying every minute.
 
 
Moving on to the filters, I’ll start by saying, I’m not a huge fan. When testing the polarity switch and filter control, I heard no appreciable difference at all, regardless of the position, so I left them in positive & Bit Perfect respectively. There is a possibility that they would have a greater effect on speakers if the DAC was used through the line out, but I never got the chance to test it that way. I don’t know if the Xbass+ and 3D+ switches are considered filters, but even though I didn’t use them much, I did hear an effect on the audio when using them. The Xbass+ seemed to have an effect primarily on the sub bass, whereas the 3D+ is intended to be a spatializer of sorts, to widen the perceived soundstage. I found the 3D+ to effect the treble mostly and added some “grain” up top. I mostly left these off, but did occasionally find them helpful when used together as a sort of loudness control, adding a bit of clarity for low level listening. My personal preference (and recommendation to RHA) would be for the iDSD BL to have an adjustable treble and bass control, +/- 5 or so, which seems to me would be a more universally useful tool.
 
 
Since fortune smiled upon me and I happened to have the RHA Dacamp L1 (also priced $549 USD) on hand at the same time, it seems only appropriate that I give my impressions of both.  Build quality between the two is about on par, with the RHA being just a tad more robust overall IMO. The RHA also has the smaller more portable form factor: it’s smaller in every dimension. The RHA has a balanced headphone output as well, but it’s a 4 pin mini XLR input, which seems to only be compatible with their own headphone the CL1 Ceramic (at least I don’t know of any other headphone using that connection). Furthermore, the benefits of using that connection was not readily apparent…it sounded just about the same when used single ended or balanced (reviewer Brooko did record measurements that seem to back this up). The RHA does have bass/treble controls (+9/-3 for both) and 3 gain levels, but the iDSD BL has 5 gain levels, Xbass+, 3D+ and a preamp output. They both can be used to charge a dying cellphone, have about the same battery life/charge time and have digital inputs (coaxial and optical for the ifi, optical for the RHA). I’d say all the bells and whistles come down to a matter of preference, and I’d give RHA a slight advantage being more portable. Ergonomically, there isn’t too much to complain about in either case. The biggest problem with the ifi is a somewhat crowded front panel, on the other hand the volume wheel RHA chose, while having better resistance than the ifi, is much harder to control…it steps up in volume more rapidly and is awkward to turn. Sound quality is where the rubber meets the road, as they say, and sonically I’d say it would be a matter of preference. Power output seems comparable overall, with the ifi being more versatile (at least 5 different gain levels). While I find both of these to be on the warm side, I’d say that the ifi is more on the analytical side of warm, while the RHA sounds a touch smoother. These are not night and day differences, and there was no clear sonic winner for me. I’d honestly be more than happy to have either of these in my audio chain. I lean slightly toward the ifi, simply because my DAPs utilize coaxial outputs and I could see myself using that often, but that could easily change with a DAP upgrade.
 
 
I am truly sorry to see the iDSD BL leave. In my opinion, except for some small niggles, ifi has done a great job with the iDSD BL. It’s well built, very versatile, has plenty of power on tap, and sounds fantastic. The price is a bit high, but you do get a lot for your money. My thanks again go to Lawrence and ifi. After spending a week with the iDSD, I can definitely recommend checking it out if you‘re in the market for a DAC/amp. It is definitely worth a listen.

iFi micro iDSD Black-Label - In-Depth Review
 
 

The iFi micro iDSD Black-Label is the improved version of the previous iFi micro iDSD. iFi has shared to us in detail, many of their design considerations during the development of the micro iDSD. Lot’s to learn from the post, therefore I think it is worth to post the link to the early discussion here:

http://www.head-fi.org/t/711217/idsd-micro-black-label-tour-details-page-147-release-info-page-153

I bought the iFi micro iDSD pre-ordered from Stereo Singapore in September 2014. Since then it has been one of my favorite portable DAC. I like the line output sound quality especially when paired with iFi micro iCan, but the headphone output of iFi micro iDSD requires some matching to sound best. My biggest complaint so far from the iFi micro iDSD is the quality of the iEMatch switch that often glitchy and causes loss of the right channel or severe channel imbalance. The volume pot of my iFi micro iDSD also has audible channel imbalance below 9:30’ position. Together with the glitchy iEMatch switch, it makes me difficult to use it for sensitive IEMs. I’m glad to say that I found the channel imbalance of the review unit of the iFi micro iDSD Black-Label has been greatly reduced, and practically I didn’t have any channel imbalance issue even at low volume setting. I hope this will be the case for all iFi micro iDSD Black-Label units. I also hope that the iEMatch switch durability has been improved on the Black-Label version.
 

 

 

Some of the improvements in the Black-Label version are some of the electronic components, power sections, clock system, and some other improvement on both digital and analog circuit sections, including the implementation of custom Op-Amp. There is no changes in the technical specifications and features from the previous iFi micro iDSD, so feature wise both the iFi micro iDSD and the Black-Label version are similar. The improvement is more on the sound quality. One might ask when there is an improvement in the sound quality, why it is not shown in the specification? The simple answer is, the measured specifications don't cover all aspects of the sound quality. Basic specifications such as FR, THD, and SNR are only a few aspects of the audio quality and quite often are not advertised in detail. THD for example, usually only advertised as average THD, but manufacturer usually doesn't give further detail like what is the distortion profile across the audio band, which type of distortion that is more dominant, etc. Therefore, usually, it is close to impossible to judge the sound quality of a DAC or Amplifier only by looking at the advertised specifications.

In summary, iFi micro iDSD Black-Label is an excellent sounding, feature rich DAC + headphone amplifier. It does require some knowledge to get the most out of it. Sound quality wise, it is on the neutral side with no obvious coloration. For those who are looking for warm, intimate, mellow type of sound signature, better look elsewhere. Transparency, clarity, speed, and detail retrieval are still the main characteristics of iFi micro iDSD Black-Label sound signature, similar to the iFi micro iDSD. And iFi has improved it further in a more musical manner on the Black-Label version. Besides some technical improvement from the previous iFi micro iDSD, the sound quality improvement that I observed on the Black-Label are transparency, dynamic, and instrument separation. The Black-Label is more transparent and realistic sounding than the already transparent sounding iFi micro iDSD. Not a night and day differences, but noticeable. And I’m glad to say that the increase in transparency and detail retrieval doesn’t make the iFi micro iDSD Black-Label sounding more analytical than the iFi micro iDSD. Subjectively, iFi micro iDSD Black-Label is actually sounding more musical to me. Even though not by much, I do prefer the iFi micro iDSD Black-Label sound quality than the iFi micro iDSD.
 

 

Pros:
  1. Feature rich with high performance to price ratio.
  2. Neutral sound quality with superb transparency, speed, and detail retrieval.
  3. Good multi-platforms compatibility with various operating systems.
  4. Isolated USB and analog ground with excellent USB EMI noise rejection.
  5. Various digital and analog filters to suit listening preference.
  6. A wide range of gain and headphone output power settings to suit various loads, from sensitive IEMs to demanding headphones.
  7. Useful and good sounding analog bass boost and stereo enhancement analog circuit.
  8. Good battery life.

Cons:
  1. 1-2 seconds of silence at the beginning of playback (from a stop). This short period of silence causes the first 1-2 seconds of the song gets muted at the start. This can be quite annoying for some songs that start immediately at the 1st second. This is the only most annoying flaw of iFi micro iDSD Black-Label so far, but I believe it can be fixed by firmware update if iFi is willing to fix it, or probably by releasing a special driver only for PCM playback. I notice that the silence period is slightly longer on the iFi micro iDSD Black-Label compared to the iFi micro iDSD. Due to the short review time, I’ve only tested it with foobar v1.3.12 (WASAPI and DSD ASIO). Probably there is a way to shorten the silence from the setting, but I didn’t have enough time to play around with the setting or checked this symptom using other media player applications.​ This short period of silence at the beginning of playback is could be due to ‘pop’ issue described here:
          http://ifi-audio.com/audio_blog/pop-goes-dsd-why-does-this-happen/
  1. 1 LED indicator to indicate many operating conditions. It is not user-friendly to expect a user to memorize so many color codes from a single LED indicator.
  2. Volume level indicator is hard to see.

Suggestions for improvements:
  1. To shorten the start play silence.
  2. A more user-friendly LED indicator. Suggested 3 LEDs indicator as described at the end part of this review.
  3. White or silver volume level indicator for better visibility.
  4. Better design rubber feet with a stronger attachment to the metal case. It is preferable to have better rubber feet that have been fixed to the metal case from the factory.

Audio-Technica ATH-MSR7
Beyerdynamic T1
HiFiMan HE-6
Massdrop HD6xx
Sennheiser HD800

Brainwavz B200
DUNU DN-2000
 

 

Headphone Output Sound Signature:
Transparent with good detail and dynamic is probably the simplest way to describe iFi micro iDSD Black-Label sound signature. Generally, it sounds quite neutral with no obvious coloration. The iFi micro iDSD Black-Label is not a warm and mellow sounding type of DAC that tends to ‘beautify’ recording flaws. It is a bit on the dry and analytical side, but iFi has done it in a nice and musical way. It is still lean on the analytical side but it doesn’t sound thin. iFi micro iDSD Black-Label has excellent stereo imaging, spacious and holographic with good depth. The headphone output is powerful with lightning fast transient, always giving the impression that it can drive any IEMs and headphones with ease. iFi micro iDSD Black-Label might not be for those looking for smooth warm and polite sounding DAC, but I imagine that the Black-Label could easily be the sound engineer favorite portable DAC.

With the mentioned headphones and IEMs above, I prefer to match the iFi micro iDSD Black-Label with the less analytical sounding ones. Though pairing the iFi micro iDSD Black-Label with HD800 and T1 give and impressive transparent and holographic sonic presentation, but overall still rather too bright for my preference. The iFi micro iDSD Black-Label despite the small size also surprisingly able to drive the HiFiMan HE-6 quite well, but the pair also a bit too bright for me.
 

 
 
So the headphones and IEMs that I consider pairs well with iFi micro iDSD Black-Label are:

Audio-Technica ATH-R70x
Philips Fidelio X1
STAX SR-L300 + SRM-252S (Connected to Line Output)

AK T8iE Mk2
Brainwavz B200

Most surprising is how iFi micro iDSD Black-Label improves the sound quality of the new Brainwavz B200, dual BA drivers IEM. B200 usually sounds polite with soft treble with my Onkyo DP-X1, not so much excitement. But when driven from iFi micro iDSD Black-Label, the treble suddenly shines and sparkling nicely. B200 sounds more lively and exciting with iFi micro iDSD Black-Label. Quite a significant improvement. The Audio-Technica ATH-R70x and STAX SR-L300 + SRM-252S (Connected to Line Output) are also wonderful pairs with the iFi micro iDSD Black-Label.
 

 


Comparison to iFi micro iDSD Headphone Output
At the same volume level, the Black-Label sounds more powerful with greater dynamic and sense of driving power. Bass sounds slightly thicker, tighter, punchier, and has a better texture. I feel both bass and midrange texture and micro dynamic seems to be improved on the Black-Label, giving a slightly better perception of depth, transparency, and instruments separation. Treble is more or less the same, but on some recordings with sibilance, the sibilant sounds a tad more prominent on the older micro iDSD, and a tad less sharp on the Black-Label. Just a tad, basically the difference is quite small. The level of treble and treble sparkle are about the same, but with slightly different character. The sparkling character of the treble of iFi micro iDSD Black-Label is somehow sounding a tad more natural to my ears. In summary, the Black-Label sounds more transparent, bolder, and more energetic than the previous micro iDSD. The difference is audible but not a night and day kind of differences. What I mean is, that if we already have the micro iDSD, I think it is not necessary to sell it to get the Black-Label. But if I have to choose, I would definitely choose the Black-Label over the silver micro iDSD.
 

iFi micro iDSD Black-Label Line Output + iFi micro iCan
I remember that in past, ever mentioned in the forum that some suggested to iFi to tweak the headphone amplifier of the micro iDSD to be closer to the sound signature of the micro iCan. So is the headphone amplifier of the iFi micro iDSD Black-Label now sounds close to the micro iCan? Well not quite yet. The headphone output of iFi micro iDSD Black-Label sounds dryer than the iCan. In my opinion, the iFi micro iDSD Black-Label line output connected to micro iCan still sounds better. They do share some similarity, like the level of transparency, detail retrieval, and dynamic are probably about the same, but the micro iCan sounds slightly smoother and warmer that makes the micro iCan more friendly for analytical headphones like HD800 and T1. The micro iCan has slightly longer decay than the Black-Label headphone amplifier that makes it sounds less dry and more pleasing to my ears. I’m still hoping that one day I could have a new generation of micro iDSD with the headphone out sound quality that is similar to the micro iCan sound quality. So I don’t have to bring two units to enjoy the sound quality of the combination of micro iDSD + micro iCan. In the past, I’ve compared the line output sound quality of my micro iDSD to bigger and more expensive desktop DACs, and micro iDSD line output has been proven to exceed its price bracket. iFi micro iDSD Black-Label line output doesn’t disappoint and even improved it further on the transparency, detail, and instrument separation. Very impressive line output sound quality from such a small portable DAC. IMHO, iFi micro iDSD Black-Label is worth it even just for the DAC section alone.
 

 

 
 

Chord Mojo (Headphone Output Comparisons)
Listening to classical DSD tracks, Super Artists on Super Audio sampler vol.5 from Channel Classics Records, when using the analogy of medium and large concert hall, Chord Mojo sounds like we are listening to the concert in a medium size hall, with a tad better micro detail and impact. Listening to Chord Mojo is like sitting closer to the musical performance, more intimate presentation with a tad clearer micro detail and slightly better sense of micro-dynamic. iFi micro iDSD Black-Label, on the other hand, provides a more spacious sensation, like listening in a larger hall. Less intimate with a larger sense of space. iFi micro iDSD BL is also perceived as a tad smoother sounding than Mojo. The difference is not day and night, but quite easy to distinguish. Both performs admirably in their own ways. I do need more time for better comparison between Mojo and iFi micro iDSD Black-Label, but the most distinguishable difference is in the presentation, between the more intimate presentation of Mojo and the more holographic presentation of iFi micro iDSD Black-Label. Honestly, I can’t really tell which one is better. I guess it is not for better or worst but more about personal preference.

iFi micro iDSD Black-Label - In-Depth Review
 
 


iFi micro iDSD Black-Label is probably the most unique and feature rich DAC+Amp combo in its class. The Black-Label version is a proof of iFi main priority in their design philosophy, which is sound quality. The Black-Label version has similar features to the older version of micro iDSD, and all the effort and improvement is only to achieve one goal, better sound quality. And I think iFi has achieved it. Kudos to iFi!

nice!  I am still waiting on it.  I am near the end of the line for review.  I am also on the list to review the new Aune S6.  I am looking forward to that comparison!  
 
I am curious about the cutoff you are talking about on PCM material.  Is it on PCM only?  Correct?  Hmmm.  Let me get my iDSD Micro out and have a listen.  This is not something I recall experiencing with my PC.  I think if I did have that issue I would remember because I would find it extremely annoying.  That is still one of the maddening things about USB audio, and I am sure it drives these companies crazy...  especially with PC audio, since hardware configs are practically unlimited in possible combinations, it is probably impossible to get it perfect for everyone.  
 
I know over time these little glitches in the iFi software have improved immensely.  To the point where I felt the user experience was a good as one could expect considering all the functionality.  The software has come a long way, and I think that shows you both sides of the coin when your relatively small company has its own in house software and design team.

@MLGrado, Looking forward to your review!
The initial silence is short on my micro iDSD, but a bit longer on micro iDSD BL that starts to get me annoyed. Hope I could find the right setting with foobar to get rid of it.

Build and Finish: Surprisingly lengthy unit made out of machined aluminum. Decent weight with quality metal switches and knobs. The iDSD is well-finished, a quality product with no quality control issues. On the back of the unit, iFi Audio was thoughtful enough to place a detailed specs report for easy consultation.
 
Accessories: I’ve never seen a product come with this many accessories before. iFi Audio definitely wanted the consumer to have every single option available for the long haul.
The original packaging is also quite useful. It comes with a foam insert, that allows you to place the iDSD back in its original alignment. The box serves as a carrying case of sorts.
 
Comes with: 1x Velvet Pouch, 2x Detailed Instruction Cards, 1x 3.5mm Male to 3.5mm Male Adapter, 2x Silicone Bands, 1x 90° Male USB to Female USB Cable (Type A), 1x Female USB (Type A) to Female USB (Type B) Cable, 1x Purple RCA Cable, 4x Rubber Soles for Amp, 1x 3.5mm to 1/4th Adapter, 1x Jumper, 1x Short Female (Type A) to Female (Type B) Adapter, 1x Blue USB 3.0 Male (Type A) to Female (Type A) Cable
 
Technology and Design:
 
The Micro iDSD is easily the most technologically well-equipped product I’ve seen from a manufacturer. For the price, you’re getting so much to work with.
 
First off, supported playback includes just about everything under the sun. It’s definitely future-proof with Octa DSD 512, Double DXD 256, and PCM 768 playback.
 
Additionally, the iDSD can drive just about anything under the sun with 10V of power @ 16 ohm when “Turbo” mode is selected. This includes orthodynamic headphones such as the HIFIMAN HE-6.
The iDSD is designed around getting the cleanest signal from the amplifier/dac to your headphones. There’s a built-in iPurifier on the rear USB port, eliminating EMI interference on its way to the iDSD. For the DAC section, there’s an ultra-low jitter Femto clock--something I’ve never seen at this price range.

There are also three filter options (PCM, DSD, DXD), iEMatch for IEMs sensitivity matching, X-Bass, 3D Holographic Sound, and a power socket on the right side where you can utilized the iDSD to charge your portable devices. Yes, you can use the iDSD as a charger. iFi Audio has even included that as an option.
 
Included accessories are also a bonus. You have everything you could possibly need to get started.

 
Sound / Comparisons:
 
All listening was done on Eco or Normal Power Mode, - Polarity, Bit-Perfect Filter, iEMatch disabled, X-Bass and 3D Holographic disabled. I found this offered the most neutral and true flavor of the original recording. I won’t be commenting on the results of experimenting with these settings.
 
I found the iDSD a very interesting listen. Quite frankly, it’s as close as you can get to reference for the price of $499. However, I have a hard time giving it the ultimate nod for transparency and neutrality. Even with all its technology, at the heart of the iDSD is still the Burr-Brown DAC chip. This gives the iDSD a slightly warm tinge that’s most evident with neutral headphones like the Ether or the Audio Technica R70x. That’s not to say the iDSD is lacking in details. In fact, I would say the opposite is true. I had no trouble hearing all the subtle nuances in each track, and I didn’t hear any flaws smoothed over despite the warmer presentation.
 
For most people, the iDSD offers a clear improvement over lesser offerings and a window to musically accurate sound. Fundamentally speaking, the iDSD works well with just about every headphone on the market. It also always manages to sound just right; the soundstage is never too expansive and is often portrayed with a good sense of intimacy. But on tracks that require a medium to communicate an effective sense of space, the iDSD doesn’t disappoint either.
 
Bass is tight, well-rounded, with slightly above average dynamics and impact. On a headphone like the Ether, I looked to hear the sub-bass and excellent bass response. The iDSD did precisely that, without over-emphasizing and glossing over the bass details I’ve grown accustomed to.
 
Mids and vocals are fairly neutral, I didn’t feel as if the iDSD was particularly forward or distant. In my mind, the iDSD passed the realism test. Vocals sparkled when they should, crooned when called upon, and sounded pretty darn good overall.
 
The treble on the iDSD is slightly accentuated. Perhaps this has something to do with the house sound of iFi Audio, since the iDAC2 and other offerings I’ve tried have a similar presentation. The iDSD, fortunately, has the least coloration of all its brethren. The treble sounds quite lean juxtaposed against the full-bodied and warm bass thumping in the background. I’ll have to say I prefer this dry and slightly analytical treble personally. It makes Electronica and Rock music a pleasure to listen to, similar in the way Grados handle treble (but without the harshness).
 
The iDSD also excelled at imaging and transient speed. Fast and difficult recordings were played back without a hitch with perfect instrumental placement. It is this particular trait, coupled with an  “open” sound that allows the iDSD to be considered reference in my book.
 
While not as musical as the Mojo, or as dynamic as the Concero HP, the iDSD nonetheless holds its own as a contender for one of the better portable amps/dacs. It serves as an all-purpose and well-honed unit that offers so much possibilities in terms of playback and usage.
 
Clarity, cohesion, openness, and accuracy. The Micro iDSD has all of them in spades.
Conclusively, I highly recommend the iDSD for a long-term purchase that doesn’t disappoint.

Introductory word
 
They say that once you go black.... yeah. This is quite self-explanatory. And behold, black iFi Audio product emerged. I can only say - finally. Cheers to 'em English folks. Even though I enjoy iFi stuff, I had a pleasure to know said manufacturer's every device out there, silver color doesn't make me pleasantly anxious. Don't get me wrong, it looks OK. It fits where it needs to fit. Though I wondered if we'll see black puppies from iFi, that was my desire number one for a long, long time. And to know that BL version is supposedly better than stock iDSD is yet another reason to be happy. Improvements are usually good in our hobby. And if a company with very extensive know-how is able to further improve its circuitry here and there, the outcome surely is something to look forward to. So we looked forward, waited. And waited. And then waited some more.

My experience with iDSD Micro was very enjoyable overall. In order not to make this story longer than needed (it's long enough), let me just say that for the price, this was and still is IMO a very nice product to have. I believe that it defended itself over time, it held its ground firmly against numerous rivals. Several of my friends own one and are perfectly happy. Yes, they do AMR window shopping, but are happy nonetheless. When I used my iDSD Micro on the go with a laptop, its one feature stood out of the crowd, namely organics. With right tracks and right CIEMs/headphones, this deck had it. This lifelike, rich and musical approach I subjectively enjoy and pay attention to since literally forever.
 
_MG_3302.jpg
 
Original iDSD sound wasn't thin, dull, fuzzy or unpleasant in any way. For the money it was simply right. Chord Hugo elevated this experience to even greater extent, but for a completely different, much higher asking though. When my buddies asked me about a transportable DAC/amp combo they should buy, I suggested to go with iDSD Micro as a complete have-it-all package that'll cover most of their needs. If budget to spend was higher, Hugo was my pick. After many sources auditioned, my all time favorites up to $3'500 were iDSD Micro, Hugo and desktop AURALiC Vega in that logical order exactly, namely from the most affordable to the most pricey.
 
_MG_3290.jpg
 
Years have passed, iDSD is no longer with me and the same story is with Hugo. I'm a home stereo person of heavy calibre these days. But iDSD BL is something I noticed in an instant. One of my friends planned to grab one unit for his own needs anyway. Needless to say, I've exploited his kindness. In short, to evaluate iDSD BL's skills, ENIGMAcoustic Dharma D1000 and HiFiMAN HE-1000 V1 cans were very helpful in writing this piece. Apologies for not being able to compare said English deck to any competition as I currently don't own anything suitable for the job.
 
Functionality and stuff
 
Before we'll dive into the sound, a word about fit'n'finish and said product's functionality. iDSD BL is a typical iFi Audio device, nothing much can be said about it as there's been a lot of reviews out there already. That's hardly any surprise at all. In any case, black iDSD Micro looks dandy. Subjectively this color is great, much better than the original. Stealthy impressions, anyone? Yes, please. And the paint job itself is done nicely too, even all across the product's chassis. Orange writings do the trick nicely as well. Perhaps this is just me, but black&orange mix is something that IMO simply works. My only gripe is with our English deck's bottom. Some descriptions visible there are orange, whereas vast majority is black, therefore unreadable while looking directly at the product. This could have been done better. Therefore please iFi, put orange lettering everywhere. The product is durable, every part of its chassis is nicely finished and properly matched. Rubbery knobs look more decently than in the original, namely aren't wobbly at all, but my memory might not serve me well here. 3D and Xbass knobs feel solid and properly clicky. I can't remember how these functions were implemented in the first iDSD Micro. But their input is very audible.   
 
_MG_3305.jpg
   
As far as iDSD BL functionalities go, things are as good as they get for the price. This device can be used as an S/PDIF converter which I've exploited in home stereo with ease. FPGA based Audiobyte Hydra-X+ was audibly better in this task (greater resolution, even punchier and organic sound, a bit blacker background and wider imaging), but not by a lot. And Audiobyte's thing was sold for about $800 or so, these days it's in EOL state. Moving on, the ability to bypass iDSD BL's volume control is handy. Just for the sake of this review I've tried this product in standalone and heavy $$$ environment solely as a source and it handled itself in there nicely. Nowhere near my main DACs (LampizatOr Golden Gate, AMR DP-777). Yet to a point where the switch from said sources wasn't painful, which is more than surprising. Volume bypass will be probably very rarely exploited, but it's good that iDSD BL's signal path can be shortened when needed.
 
_MG_3293.jpg
 
iEMatch works as intended, we'll return to this topic down below, for now I can only write that it simply does the job with my Vision Ears VE5. I'm not a huge fan of filtering of any sort, therefore bit-perfect mode is my path with every source out there (LampizatOr excluded for obvious reasons, DSD upsampling is mandatory in this product's case). And during two weeks spent with iDSD BL I have to confess that I've used it as a power bank two times. Not much to say here, it charged my phone no questions asked and literally saved the day.
 
_MG_3295.jpg
 
Some people might be picky about iDSD BL's size and I understand this as its bulky. But once my mate shared it with me, I've always had it with while going to work, to a point where it became a habit. To have it developed in such short time counts for something. And once on the spot, iFi's deck worked with a laptop all day. Needless to say, I got attached to it as quickly as with the original iDSD Micro years back. And I got used to iDSD Bl's size, that's not an issue for me as I don't do smartphone + DAC/amp rubber-strapped on-the-go combos, that's not my thing. Functionality wise, iDSD BL covered all of my needs and in proper, predictable fashion. This kind of a package for this kind of dough I consider as a steal. YMMV, though. In the end, would I change anything in said machine's design/functionality? Orange writing aside, at the moment no, not really. Perhaps over longer time span I'd nitpick something, but not past my two weeks adventure. The loaner turned out to be a perfectly healthy deck. No hiccups, hisses or any other unpleasant surprises happened along the road. And dead silent too.
 
Sound
 
Let's move to sound quality. iDSD BL was used solely as a transportable integrated solution as this is its main function. My guess is that vast majority of you out there use that exactly and rarely anything else. Vision Ears VE5 came in as the first order of business. These are sensitive, midrange focused, bass light and wide sounding little devils. What they need is a bit more body and shove downstairs to sound properly. iDSD BL delivered just that and without any resolution loss. Also, this transportable deck doesn't sound sharp at all once burned-in. At least not with highly resolving VE5 CIEMs. These not only sounded clean and very informative, therefore as per usual (...and presumably to iEMatch tech inside iDSD BL), but also properly punchy, with spot-on texturing and imaging as wide as per usual. In short, I couldn't single out one particular element of this listening session that bothered me. Perhaps because of my subjective, not overly analytical and at times forgiving approach. When the overall experience is simply enjoyable for me, I'm not into pigeonholing. And that was the case with iDSD BL and VE5 combo. It was pleasant and highly synergistic, simple as that. Come to think of it, Lotoo PAW Gold provided me with even more lifelike experience a while back, yet for what iDSD BL is, it turned out great with said German CIEMs. A word about Xbass trickery is in order, though. With VE5 this works like a charm. In short, Xbass pumps up both the lowest and above departments in said CIEMs in a particularly great fashion, yet at no cost at all. I can't say the same thing with D1000, these cans subjectively don't need it. But VE5? Holy cow...    
 
_MG_3307.jpg
    
Moving on, it was high time to use the main headphones - HE-1000. Their slightly mellow, wide and enjoyable character pushed all my buttons in an instant. These cans are the reason why I sold my Sennheisers HD 800 and never looked back. The distinctive difference between these two models is in company needs. 800s crave for a very specific amplification to sound good, usually times more expensive. Picture Bakoon HPA-21, Trilogy 933 and (poor version) old Phoenix amp by Audio-Gd. HE-1000 on the other hand will go with literally everything out there in more enjoyable fashion. Heck, I've had a blast with these and HiFiMAN's SuperMini DAP. It didn't drove 'em to their full potential, but the outcome was pleasant still. I expected nothing less from iDSD BL. In short and in above mentioned headphones' case, this deck provides what's needed.
 
_MG_3296.jpg
 
First of all, this transportable machine has lots of juice to handle HE-1000, which roughly translates to properly punchy attitude. Said cans can be a bit too mellow and watery (yet not boring!) at times, but with iDSD BL the sound is honestly feisty and engaging. Proper crack and shove is there, nicely rounded, generously textured and not overly contour or stiff. The gist is that their amazing soundstage is as wide and deep as usual, nothing is missing in there. The layering is grand too, one can peel off rows one by one with decently recorded tracks. And at this point it's worth to know that iDSD BLS as a package is slightly on the warmer side. Not cold, bluntly warm or plainly fuzzy and overly cozy in the process. It is simply spot-on in that regard, even though not being neutral in 100%. The density is there too, but not overbearing. HE-1000's bass never became boomy or unpleasant, but what it had instead is both proper control and great texturing. The midrange felt quite vivid and clear at the same time, the resolution was there too. To hear all 'em tasty details properly flavored, vibrant in the process and without any veiling at all is a fabulous experience in general.
 
_MG_3303.jpg
 
HE-1000's highs were decent too, without metallic tint, yet finely decayed, smooth and present. There was no need to either tighten their screw or make it a bit loose. Yet again, YMMV. But what stood out of the crowd is this 'organics' feature I've mentioned above. The gist is that iDSD BL and HE-1000 combo is tangible, vivid and with this lifelike tissue present all across the board. This in my book seals the deal as said feature is the one I'm subjectively after. It distinguishes good equipment from great one and said iFi's deck is able to pull this off. I could now dive into "I'd tweak this, I'd tweak that", but that'd be unnecessary nitpicking past HE-1000 experience. Let me simply state that the outcome was very involving and subjectively enjoyable as a whole. And at this point it was clear to me that iDSD BL doesn't fulfill the magnifying glass duties, it's focus is in texturing instead of sterile dissection. And that's always good for this audiophile.
 
_MG_3291.jpg
 
Next in line were Dharma D1000 cans. I'll allow myself to be somewhat shorter here, as HE-1000 was my main evaluation tool. The initial observation was that these headphones' rich, expansive and well-textured aspects behaved as per usual with iDSD BL. Said transportable piece allowed them to be what they are. Simple, ain't it? The bass was punchy, well-bodied and was of pleasant nature in general. It didn't sound distorted and with ENIGMAcoustics product that was the case once or twice. But the lowest extension wasn't there, it was hard to shake off the feeling that these cans put emphasis on upper bass region. Additionally, their tonal balance is usually shifted a bit towards downstairs department and this was heard as well. But because of SBESL driver, the FR is complete nonetheless, or at least it feels like it. These features make Dharma D1000 a rather unique performer, peculiar to say the least, yet pleasant overall. My point is that iDSD BL showed all that and of proper quality. Bass we've already covered, yet moving above things are tasty too. Grain-free, smooth and texturally rich vocals among other things simply work. I honestly hadn't had a viable reason to complain.
 
_MG_3306.jpg
 
Yes, HE-1000 gets this midrange job in even better and more organic way and price wise it should. But Dharmas represent somewhat similar, joy focused approach and iFi's product is perfectly capable of delivering it. Highs are one of American cans' trademarks. These are nicely extended, have proper body and are free from overbearing shininess. Some good words can be said about imaging as well. Everything is in order there, though in D1000 case it was heard, that iDSD BL tends to paint a picture somewhat shorter than usual. That wasn't the case with HE-1000 or VE5, on the contrary to this paragraph's main cans. The same story is with resolving power, it was slightly decreased with these and again, I had no reasons to be vocal about it during two other models' listening sessions. The gist is that the overall experience was of enjoyable sort. I got the impression that iDSD BL was able to show their character in a proper way. The outcome was less spectacular than with HE-1000, but that was somewhat expected. And Dharmas D1000 are strange.
 
Summary
 
 
 
I'll try to make this chapter as short as possible. iFi Audio iDSD BL is a great product to have. It's well-made, exceptionally versatile, quite convenient to use, has enough power to handle literally every set of cans out there and it's price-to-performance ratio is - in my humble opinion - off the charts. I can't tell, perhaps for iDSD BL's $549 asking, things can be different sound wise, to some of you even better. But what counts for me is that this English deck sounds really good and it sports that organic, tension-free and tangible approach, which I never have enough of. Hence if someone asks me what transportable and affordable device to buy, "Go for iDSD BL, you'll thank me later" is my answer.

New Head-Fier
Pros: Noticeably improved bass and smoother sound compared to the original.
Cons: Volume knob position is hard to see on the black edition. I prefer the look of the silver to the black.
First of all, thank you so much to Ifi-Audio for sending me a black edition to review for free! Really awesome of them to involve the audio community to such a degree.
 
I will keep this review relatively simple. I have the original silver Micro iDSD so it only makes sense to compare the two. I A/B tested the two units side by side while listening to some go-to tracks on my HifiMan HE-500 headphones. I had XBass enabled and 3D disabled for every track (just my personal preference). I did my best to volume match them by ear but I’m sure it was not perfect.
 
Tracks I used for testing:
 
Kurt Vile - Wheelhouse
Danny Brown - Get Hi
Neon indian - Local Joke (tons of sibilance on this terribly mastered track, so a good test)
Dirty projectors - About to Die
Dinosaur Jr. - Plans
Matthew Dear - Ahead of Myself
 
After listening (and re-listening) to these 6 tracks I found that I was hearing the same differences over and over again and so I felt comfortable sharing my fairly conclusive findings.
 
Results:
 
  1. These two units are different but not to a startling degree. They are still similar in overall sound.
  1. The clearest improvement to the Black unit is far and above the bass. The bass goes deeper and hits harder. This was apparent in every song. The added bass makes listening to the Black edition quite enjoyable. I will miss the added bass when going back to my original Micro iDSD!
  2. Time and time again I found the Black unit to be smoother than the original Micro iDSD. Sibilance is less noticeable on poorly mastered tracks and the overall presentation of the music is easier on the ears. The black edition sounds silky where the silver, by comparison, sounds more dry. The black sounds cleaner and has a sound signature that is a bit more immersive.
  3. The black edition has an improved soundstage, but only marginally so. It seems deeper and more realistic.
  4. Detail retrieval is basically identical between the two units. I found that I sometimes noticed details more readily on the Silver unit but that could be because it sounds slightly “brighter” than the black.
  5. When I briefly tried out the 3D setting, I found it to be much more enjoyable than on the original silver unit. I never use it on my old unit because it makes the sound too bright for my taste. The 3D enabled on the black edition colored the sound it a pleasant, perhaps more immersive way. I could definitely see myself using 3D on the black edition.
 
I think that the differences between the two units can be distilled to this:
 
The black edition is a marginal but not insignificant upgrade to the original. The bass is much improved and it sounds smoother overall.
 
That being said, would I upgrade to the black edition? Probably not. One reason I wouldn’t is I actually much prefer the look of the silver unit to the black edition. It looks more high-end in my opinion. One thing that quickly annoyed me about the black edition is the inability to see the position of the volume knob. Such is the trade-off with black-on-black design. A dark grey unit would be the best of both worlds, in my opinion.
 
I think if you are buying a Micro iDSD for the first time, shelling out the extra cash for the black edition is an absolute no-brainer. Do it. It’s an excellent sounding unit - Ifi-Audio moved the ball forward on this one and the original was (and is) fantastic so that is no small feat. Upgrading from the original to the black is a harder decision. I would personally be more inclined to upgrade to something that is a big jump in quality, not an iterative improvement.

iFi Micro iDSD BLACK LABEL
 
Packaging and Build Quality
 
The iDSD Black Label came packaged in a sturdy, well presented box. Most welcome were the plethora of accessories that it came with. Multiple different kinds of cables, connectors a storage bag and even rubber feet for the main unit. The lack of accessories is one complaint I've personally had with several other mid to high end audiophile amps/dacs, etc... iFi certainly didn't skimp in this area and I'm very happy they didn't. Also included was a small, but very well written instruction manual/guide.
 
I was pleasantly surprised at the size of the micro iDSD BL unit itself. I actually thought it'd be bigger, but the size to me is very spot on. I was also always a little weary of the long, rectangular form factor, but it turns out it's quite accommodating. This makes it especially handy if you had a small area/work-space and real estate was a premium. The unit feels very sturdy and has a good weight to it, but it's not excessively heavy for portable use. I must say, the black matte finish with the orange markings looks fantastic. The numerous switches located on every side of the unit (minus the top) are very well marked and have great mechanical and tactile feel. I only had a few issues with the physical build of the micro iDSD BL. My biggest was with the placement of the sole LED indicator. It's placed towards the top/rear of the unit on a bevel and if placed to the left of you, is impossible to see. Placement towards the front of the unit, possibly right above the volume pot would be far more effective. It would also be nice if the LED, or perhaps a secondary one, would display if you are using USB Power or Battery Power. I also felt that the volume knob should have used some of the orange paint to mark the position indicator.
 
Features and Sound Quality
 
One thing for certain about the micro iDSD Black Label is it certainly isn't lacking in features. This is one very versatile piece of kit. I utilized most of the features that I would normally have if I owned this unit. That means I didn't didn't use the IEM matching as I only use full size headphones. I also didn't utilize the smart charging feature, but that's certainly a great feature if you plan on taking this unit on the go.
 
I mostly used used the Black Label with several PC's via USB. The software download was super easy and installation was a breeze. Using Foobar I went through pretty much every format the micro iDSD could handle. With the exception of DSD/DXD, everything played exceptional. The sample rate change delay was slightly longer than some units I've used, but nothing too excessive. Back to the DSD/DXD playback, I initially had a few playback issues, but they were quickly remedied by increasing the buffer size. DSD all the way up to 256 and DXD played very well after that. I also used the Black Label as a portable unit with my iBasso DX80 as a transport via digital-coax and was very pleased by the results. I didn't run down the battery completely during my testing. However, the listed playtimes even in Turbo Mode, are more than acceptable.
 
During my time with the Black Label, I used a variety of different full sized headphones with the unit. Everything I threw at it was easily powered from the HE-1000 to the HD650. I found myself mostly using the Normal and Turbo power mode depending on the headphone, although the ECO setting was nice to have especially if you wanted to get longer battery usage. The XBass Plus setting was solid as far as bass booster's go. Most of the headphones I used with the Black Label didn't really need it, but I quite enjoyed it when using my stock HD800. The 3D Matrix Plus feature was interesting, but I overall found myself not using it much. It seemed very dependent on the source material and the headphone used. On some headphones I felt it added far too much treble and on headphones with great soundstage/imaging it sometimes sounded strange. However, I did quite enjoy it with my TH900's.
 
As I mentioned earlier, the micro iDSD Black Label did a great job powering all the headphones I threw at it. I also felt the sound quality the Black Label delivered was solid. Just straight out with base settings, the Black Label delivers a fairly neutral sound. I own a Chord Mojo and decided to do some A/Bing of the two with my DX80 feeding both as a transport via Digital Coax. I consider the Mojo to be an exceptional piece of hardware and feel it delivers far above it's price class. When comparing the Black Label to the Mojo, I felt it fell behind in a few areas. Most notable soundstage, instrument separation and detail retrieval were lacking. The Black Label also felt slightly warmer than the Mojo. All this aside, the iDSD sill sounded very good and I honestly prefer many of it's aesthetics over the Mojo.
 
Final Thoughts
 
Overall the iFi micro iDSD Black Label is a fantastic portable amp/dac, especially at its price point. This is a great all-in-one unit that can be used in a multitude of ways and is able to play pretty much any format out there. I’d easily recommend it to someone who’s looking at similar priced/featured portable amp/dac units.

Pros: Sound improvements across-the-board vs. the original (silver) iDSD; greatly improved headphone sound
Cons: Hard to see volume level on volume knob (minor)
I was fortunate to be part of the iDSD BL Tour (US).  Below are my findings of a direct comparison versus the existing iDSD (silver) which I own.
 
 
IMG_20170105_184441.jpg
 
 
 
 
A couple introductory notes on my review (skip this if you just want the conclusions, though it provides useful context):
  • The set-up (pictured) is my work-at-home rig; I listen to the iDSD on a desktop set-up, rarely as a portable rig.
  • I also listen through JBL LSR305 active monitors a lot as I need to be on/off the phone for work and switching headphones to phone and back again all day is a pain. The 305s are surprisingly good for low cash.
  • I tried the setup comparison between iDSD and iDSD BL (called BL going forward) with all listed headphones but keeping the rest of the rig (iFi USB purifier, cables, iUSB) constant. As the picture shows, I had both iDSD and BL side-by-side so I could just move cables in seconds to compare specific passages, not just whole songs.
  • I did some tweaking with all kinds of settings, just for comparison, but I don't play around with these in 'real' listening – I find most of the knobs and switches useful for dialing in a good combination with whatever particular headphones I am using, then I leave them alone. However, I do appreciate the flexibility these different settings provide for personal customization.
  • For two days I listened solely to the BL. I find plugging in a new component can appear to make it sound 'better' at first mainly because it is different. I wanted to “get to know” the BL before doing any comparison.
  • Bottom line: during those two initial days, I enjoyed the heck out of the BL. It's a more immersive experience than the iDSD.
 
Summary:
  • iDSD BL > original iDSD (possibly '>>', though I hate hyperbole, especially my own)
  • BL's black color is classier than iDSD silver.....but I'm not a fan of silver, so YMMV.
  • BL has better dynamics, air, soundstage depth, and bass control.
  • BL has a fuller, more refined presentation; iDSD seems a little thin in comparison.
  • BL seems considerably more powerful.....even though the specs for both seem the same. I had to turn the volume down ¼ to 1/8 on the BL dial to achieve similar volume with the iDSD. Start low with your initial settings, fellow tour members – you could be in for a loud surprise. 
  • I think BL's 3D and xBass are better, but the difference was subtle to my ears. They may be better on the BL, but the major difference was the overall sound improvement. That seemed to dominate any differences I could hear in the 3D/XBass comparison.....but that's just me.
  • BL had me just listening/enjoying for days without any nagging critical audiophile thoughts; I can't achieve quite the same level of immersion with the iDSD.
  • The better/more revealing your headphones are, the more pronounced the difference should be.
  • One (minor) suggested improvement: it would be good if there was an orange line on the volume control notch. It is hard to see the volume level on the BL, easier on the silver iDSD.
  • Sennheiser Momentum Over-Ears recommended only for cell phone/mobile use. :)) Now I understand what people mean when people say they are bass-heavy. Bass didn't seem so pronounced using my anemic cell phone. I'll keep using them when on-the-go.....not at home.
  • I don't like in-ear 'phones pretty much at all. Not comfortable to my ears, and I've tried more than a few. Not going to pony up for custom IEMs.
 
By the end of my “tour time”, I lost interest in comparing the two and just wanted to maximize my time with the BL. The devil on my shoulder kept suggesting, “Hey Dave, just slap a coat of black paint on your iDSD and send that along to the next reviewer. I doubt anyone would notice.”
ANSWER: Yes – yes they would.
 
Job very well done, iFi. The BL is is an evolutionary improvement in most ways over the iDSD. Anyone still using an iDSD (like me), don't run it over with a truck – not that this would hurt the iDSD in any way. The iDSD is still a fine performer and I am quite happy with mine. However, the BL is noticeably better and well worth the audition, even if you are considering more expensive gear.

New Head-Fier
Pros: True hifi gear - Quality for monney - Powerfull enough output to drive power amps
Cons: none
The unit arrived in perfect condition, packaged in the  usual iFi nice boxing.
 
- The IDSD was powered through the  iUSB2 unit and an Uptone power supply
I don't use headphnes, so my judgement is only valid for the RCA output.
We connected it on two different hifi systems :
1 - Krell / Vecteur Alpha / with and without the  Audio Research Preamp. USB cables is  Absolute Creation and  Howland for the RCA and speakers
2 - A large Acoustat  44 electrostatic system, amplified with Electrocompanie mono amps, with and without a modified Perreaux SM3 preamp.
Audio files are all non compressed, mainly Classical and Jazz (P.Herreweghe/Beethoven/9th - Harnoncourt/Haydn/7th words of Christ/Teldec - McGegan/Arias for Mantegnana- Ahmal Jamal/Live concert ...)

Immediate comparison between the  Standard and Black label unit show indiscutable improvements/
- Voice are more natural, I would say more transpare,t, but without loss of impact and presence.
- Bass seems to extend deeper, lighter, but this extension comes without any negative artifact, at the  opposite of an 'Hifi' sound. There is more music there.
- The unit is more dynamic than the  standard IDSD, an loses the  slightly 'warm' sound of the  former.
Longer listening session shows that the Black label is more regarding toward the system on which it is connected than the  older one. It may reveal some defects of the others components, such as harshness or 'bummy bass.
In some cases the addition of the preamp added some warmth, but removed some neutrality and tones reality.
I clearly prefer this new unit. It is more of my taste : closer to the reality of dynamics, voices humanity and quick low response.

Once again, AMR/iFi gives the opportunity to put one foot in the 'tru living music' for many audio enthousiasts. Thanks !
I don't see any concurrence below 2000e to beat the  IDSD, and even more the  Black label. A true bargain.

INTRODUCTION:
 
When I decided to sell my Chord Mojo the iDSD was one of the units that got put on my list to research more.  If you have a box to check, the spec sheet of the iDSD BL probably does it.  Super High PCM sample rates, check, DSD, check, absurd wattage output, check, optical, USB, coax and analog inputs, check.  On top of that iFi follows some great design and build practices, high quality material and parts are standard on every iFi product I've seen to date.  
 
With my past AMP/DAC being truly portable with the Mojo and my current AMP/DAC Schiit Jotunheim) being more a standard desktop solution I found the iDSD BL to fall somewhere in between.  With a price for the BL at $549.00 and the Mojo ($529.00) coming in slightly lower and the Jotunheim ($499.00) coming in even lower than that the iDSD BL has some stiff competition to compete against in the eyes of this reviewer. 
 

 
DISCLAIMER:
 
I received the BL as part of a Head-Fi loaner tour.  It went on to the next person when I was finished with my review.   I have no connection to ifi other than this loaner tour.
 

 
HARDWARE AND SPECIFICATIONS:

Packaging & Accessories:
The BL comes in a nice box with a sleeve on the outside that has the graphics.  The inner box is like a iPhone box and there are two smaller boxes below the iDSD to hold the accessories.  There are a ton of accessories.  USB 3.0, RCA, Optical mini adapter, 6.35 to 3.5mm TRS adapter, a bag, non skid silicone mat, two silicone bands and two adapters to go type A to type B usb.  If you plan on using USB your going to need a lot of these cables and adapters as the USB input is a Type A male connector, not the typical USB type B (printer cable) you see on a lot of DACs.
 
Specifications:
http://ifi-audio.com/portfolio-view/micro-idsd-bl/
 
One of the things I see repeated about the BLs specs is its 4 watt power output.  Yes, it can do 4 watts, however that output is only into a 16 ohm load and it's likely only for a fraction of  a second.  Notice that the continuous power output figures are much lower and not at 16 ohm.  Furthermore if you look at the continuous power output (which is a more real measurement of what the amp can do) they rate it at 64 ohms and its 1560 mW.   Or wait, is it 1000 mW into 64 ohm continuous output, they are both listed on the page I linked.  
 
I'm not saying the BL isn’t capable of powering most of the headphones out there, however, I think iFi should concentrate on providing solid ( and not conflicting ) values for output instead of some values for marketing to throw around.  Additionally, those power values are given using turbo mode, yet for some reason the dynamic range measurement is done in ECO mode.  Something tells me figures aren’t so pretty when measured in Turbo mode.

I find the BL design to be a bit odd.  Is it portable or more of a desktop solution?  It's small-ish and can run off battery which would lead a lot of people to believe that it's portable product.  However, it only has a 6.35 mm headphone output, which is normally found on full-size cans.   I don’t see a lot of people rocking full size cans on the go.  Also, with the exception of the apple CCK you're going to need some type of speciality cable to hook up your your Android phone or a DAP.  The USB input is a male port and won’t work with the common cables I see being used with phones and DAPs.   Yes, optical and coax are available to mobile users, however, your aren’t going to listen to anything over 192khz and DSD is out of the question.  Additionally, all the cables they give you are for full size applications.  
 
I was pretty excited to see the 5V 1.5A port on the side of the BL  Thoughts of Volumio running on my Raspberry Pi feeding the BL while I move around the house were flying around my head.  That is until I clicked on the BL and noticed that the power to that USB port is cut when the BL is powered on.  I thought this would be nice for mobile users until I really thought about it, if my phone is dying/dead and I want to listen to music I need to charge it via a USB port.  The power port on the side of the BL is not a USB input only power.   OK, so someone with a DAP with plenty of power could listen to that while they charge their phone on the go.  Nope, useless there to, don’t forget once you power the BL on that port goes dead.  Not to mention with the BL connected to a DAP and your phone there is a mess of wires and quite a bit of bulk, not really portable.  I really don’t get how someone would use this port.  There are battery boost packs the size of my thumb that can charge my iPhone 6s a couple of times, Id much rather keep that in my bag than the BL.  
 
oNnUNod_OdbJdl-9A6C1Za1NuJ3WdDXbKFIhOe9fPdK_PrlRky5w5CUIS0kdUXnHOB5U0HrfIC7MSQULSd2UO-bWkCAiZ4OXB0aatiBInUyRVPvAggHqNKke97-pv8JsFrCKqkEv
 
OK, so the BL is more of a desktop solution.  This makes sense given the 6.35mm headphone jack and the RCA outputs (variable and fixed output available).   Then why have it use a battery, why try to make it small and powered off of USB?  If it's meant to be a desktop solution, provide a traditional power input and increase the footprint a bit, give use a bigger volume knob.  
 
I kind of get the feeling that the BL is like a swiss army knife, yes it's great when you can pull that toothpick out of your knife, or save the day with your bottle opener or some other trick tool.  To have all that stuff you're making sacrifices in size or design somewhere else and most of the time all you really want is a good knife.  
 
Build:
 
The BL and all the accessories it comes with actually are very nicely built.  The chassis feels very solid and all the ports, knobs and switches feel solid.  The black coating on the BL should hold up, if feel like I see this coating on a lot of products and it holds up well.  Overall, the BL has very good build quality and is what you would expect at this price point.  
 

 
USING THE BL:
 
The BL has three power levels, Eco/Normal/Turbo.  I kept the BL in ECO most of the time with my Ether Cs. .  Only when I needed a bit of a boost on a track with a low recording level did I use normal.  The turbo made the volume knob a bit touchy as the power increases very quickly.  With my HD6XX I used either normal at the very top of the range or turbo at the very bottom.  Small volume adjustments in Turbo with the HD6XX were much easier.
 
I used the BL via USB with two Linux variants; Mint and Arch Linux (volumio) and both times was plug and play.  Connecting the BL to my iPhone 6s via a CCK worked also and the CCK plug fits into the male USB port on the BL nicely without the need for any other cables.  On Windows (7 and 10) a driver is required.  I hate having to install drivers (this is a windows problem not a iFi problem) but iFi does make it easy, single file, click and it's installed.  It's also just a single item in your programs. (unlike Chord which left 3 or 4 programs to uninstall)
 
The battery.  It lasts a long time, I really didn’t use it in a portable situation during my review.  However, I did have it connected via optical and wondered how it would fare without its USB power source.  It lasted over night without going dead even though I left it powered on.  The one issue I have is that it cannot run straight off the USB power source, it has to get some juice in the battery if left totally dead before you can listen again.  This was one of the reasons I sold my Mojo, I guess I'm bad at remembering to plug it in at the end of a listening session. Also, if I am constantly going to have something plugged in why not just have a desktop solution with a real power source.  By the time I unplugged the optical and USB it was just as easy to unplug my Jot power cable and the USB to move them.  
 

 
HOW DOES IT SOUND:
 
First off I would like to cover some of the ‘sound enhancement’ features and switches of the BL.  
 
3D+: Maybe this didn’t pair well with my headphones or just isn’t my cup of tea but I found this ruined whatever song it was applied to.  I think the same effect could be gained with some bad EQ adjustments.  The output from the BL becomes harsh and I could never leave it on for more than a short stint.  
 
Xbass+: A bass head may like this feature.  If you like the sound signature of your headphones and just sometimes just want a bit of a bass boost this isn’t going to be your cup of tea.  There is a large boost in the bass and while it remains clean and I never heard distortion from it, it's just too much.  Some of their other products have multiple stages of this bass enhancer but the BL does not, it's on or off.  A dial or multiple stages is needed here.
 
The rest of the review is done with these two items in the off position.
 
Filter: Switching between bit perfect, minimum phase and standard resulted in no difference for me.

Overall Impressions:
 
My initial impression of the BL when I first plugged it in was that there was way too much energy in the high end frequencies.  Songs like The Chain from Fleetwood Mac would have an over emphasis on the tambourine and cymbals which became a bit distracting.  As I normally do with a review, I spent a few days listening to only the BL, let my ears become accustomed to it and get to know the sound signature.  Over this period the high end emphasis became less apparent but would still be noticeable during some songs.
 
I spent quite a bit of time listening to the BL, trying different genres and going through my normal review playlist.  I found the BL to be extremely competent and it drove my Ethers (low impedence) and HD6XX (high impedence) with ease.  I never found it running out of steam trying to reproduce low frequencies and it pulled a the detail out of my recordings that I was used to.
 
After a few days I started doing some A/B testing with my Jot.  If you look at my other reviews I generally go through specific recordings and note the differences between a known (my Jot in this case) and the review sample.  I ended up finding that I was writing the same thing over and over again so I figured I would just provide it once and save some bandwidth.
 
From a technical perspective I could be happy with the BL or the Jot.  They both power my cans with lots of room to spare and other than the BLs high end issue I noted above they are on par with how they reproduce the music.  Here and there I would think one was pulling a bit more detail than the other but without a switch box to rapidly switch it's really hard to say reliably that one is better than the other.  
 
Overall, it will come as no surprise that I prefer the high end reproduction of the Jot.  For bass and mids I really like the Jot better too.  The BL has plenty of authority and control for the low frequencies but I just prefer the Jot.  I found guitars coming out a bit warmer from the Jot, and it should be, an acoustic guitar really isn’t a cold instrument.  We are starting to split hairs here though.  
 
I think the biggest difference I noticed between the BL and Jot is I could sit back and listen to the Jot.  With the BL I was always in review mode, not really enjoying the music.  When doing my A/B tests I often end up getting off task and just listen to the music with a review sample.  That never happened with the BL, I was always listening to it and not the music or just sitting back and enjoying myself.
 

 
CONCLUSION:
 
I think the BL is a great example of what is possible today in audio.  A device that can easily be transported, plays basically every format and bit rate available, and can power anything from IEMs to super high impedance over ear headphones.  The BL provides a ton of options and flexibility, it can be used as a DAC and pre-amp for your speakers and has a wide variety of input options.  The construction is top notch and all the ports and materials are top notch.
 
Furthermore, with the exception of the high end reproduction on certain songs I think it's very good sonically too.   However,  I never really enjoyed the BL, I never got lost in the music with it, I never ended up halfway through an album wondering how I got there.  I wish I could give a characteristic or specification to express this better but I'm failing at finding a way to express it in more objective terms.
 
Finally, would I recommend the BL to someone?  With the exception of someone who has very power hungry cans and wants a transportable (not portable) solution; I would say no.  If you want a very competent portable player the BL isn’t it, it's not portable, I would only put it in the transportable category.  You really can’t stuff it in a pants/coat pocket with your DAP.  If someone doesn’t have the need for portability there are a ton of full-size and even transportable (within a house) solutions that come in at a lower price than the BL and are just as competent sonically.
 
This review is a bit short on details of the sonics of the BL but I found it really hard to spend a ton of time reviewing a product and trying to communicate every last detail about the sound when I really don’t think people should buy it.  As I said earlier in the review I feel like the BL is the swiss army knife of the Head-fi world; if you're in the market for a DAC/AMP figure out what you really need and get a ‘knife’ that does what you really need and leave the gimmicks behind.

@MLGrado I never said they compromised for cost or that it isn't a sonically good amp/dac.  Its compromised in function.  Its to big to be truly portable (ala the Chord Mojo) and while trying to keep the size down you have to compromise for things like standard connectors and on a desktop amp I like a nice big volume knob.  Furthermore the fact you NEED their cables/adapters to use the BL is just odd to me.

Hey man long review and covered a lot. though to critize it for being a bad battery charge or average dac is very hard and I have heard other stuff at higher price ponts that sound s*it that are raved about here. at end it may not be oyour sound but guess you tried the power and imatch settings to get things rite for your hphones. the cable is for droid and apple phone - they all have female a sockets. they dont make you buy their cables bro

Thanks for your insight, @silvrr. I own the original iDSD Micro and have to say I agree with most of your findings, save for the high-end being particularly pronounced (I paired mine with DT880s, for poop's sake!). I admit I was somewhat tempted to upgrade when I heard there was a new release, but the orange-on-black aesthetic and minimal improvements don't really do much for me; might just get a Jotunheim and relegate the iDSD to DAC service. Hope you're too discouraged by the negative feedback, critical reviews are almost always poorly received for some reason :p
 
I'm on Android and ordinary micro USB/TypeC to USB-OTG cables work well enough when I'm running music out of my mobile. The supplied blue one is good enough for regular desktop use. Not quite sure you necessarily have to use iFi's own stuff, though some would argue the SQ is superior that way.

And hey, I find the power-bank functionality useful! Saves me having to carry an extra gadget to and from school/work. You wouldn't believe the number of times the iDSD saved my ass when I was stranded with a dying phone, haha.

[size=17.03px]Intro[/size]

We have the iFi’s latest sorcery in our hands!
We all know iFi. For those who don’t know, iFi is a renowned audio company. They specialize in all sorts of devices, DACs, Pre-amps, Amps, Signal Purifiers, Signal Enhancers etc… They have this crazy habit of supplying you with everything you’ll ever need while using their products.. On a side note, they are a customer-oriented company. A rare thing nowadays.
 

Box Contents | Accessories

iDSD comes with a well designed, elegant cardboard packaging. You can find everything about the Black Label on the box. Specs, features, technologies…
 
Accessories are very rich. iFi thought of everything although we’d appreciate an micro usb OTG cable! Anyway, I must congratulate iFi for thinking and including the accessories like no company ever does. The only difference in the accessories between regular iDSD is the improved USB3.0 cable. It looks more durable now!
 
 
 
 
 
 
 
Inside the box;
  1. 1x Blue male USB to female USB cable (1 meter) to connect iDSD to a PC.
  2. 1x Male 3.5mm to male 3.5mm (15 cm) interconnect cable to use iDSD as an amplifier.
  3. 1x Purple male RCA to RCA cable. (50 cm)
  4. 1x Female USB Type B to Female USB Type A converter “cable” to connect iDSD to a PC with a audiophile grade USB Type B cable.
  5. 1x Female USB Type B to Female USB Type A converter “dongle” to connect iDSD to a PC with a audiophile grade USB Type B cable.
  6. 1x iFi branded, velvety carrying pouch.
  7. 2x Silicone bands to attach iDSD to a phone.
  8. 1x Silicone piece that protects your phone when you attach your phone to iDSD.
  9. 1x Female 3.5mm to male 6.3mm connector.

[size=17.03px]Design | Build[/size]
The device itself is big but not so heavy. If you are carrying a phone that is bigger than 5.2”, pairing it with iDSD won’t be a problem because they are almost the same size but does not have the same thickness. Its thickness is four times bigger compared to my phone. (LG V20)
Most of the people consider iFi products as transportable, not portable but when you include it in your daily rig and get used to it, it does not cause major problems to you while carrying. Black Label’s finish is truly mesmerizing. I am not a big fan of orange but I must say that black/orange combo worked for this device. It’s fully aluminum and does not have any loose part which makes it very durable. All sockets are gold plated. Its side and bottom switches feel like good quality rubber, Xbass and 3D switches are metal. Please look at my night shots, BL looks utterly amazing.

Improvements
MG_3972-1024x640.jpg

iFi re-designed some parts of iDSD to create the Black Label. Changes are shown below:
  1. re-designed output stabilisation
  2. OV2627 op-amps upgraded analogue section
  3. Panasonic OSCON capacitors loaded power supply
  4. OV2028 op-amps loaded DAC power supply
  5. DAC voltage decoupling based on audio-grade ECPU film capacitors
  6. GMT® Femto precision clock system power supply upgraded
  7. 3D and XBass Switches re-designed
 

 

 

 

Sound Signature | Sound Quality | Resolution

Following changes above granted a certain warmth to iDSD BL.
Increased note thickness resulted in bolder mid presentation. This alteration contributed to female vocal tonality to be more realistic. Plus, added emotion increased the perception of holographic staging. Surprisingly enough, added warmth did not influenced iDSD’s airy presentation dramatically. Same goes for the treble extension. It’s not in anyway crippled or hindered by the new changes of iDSD BL. In short, Black Label sounds more organic and musical compared to regular iDSD. I personally, always wanted my regular iDSD to sound fuller, more natural.. Well, I definitely got what I wanted!
Resolution is pretty much the same, however 3D switch do improve the perceived detail and texture little bit, which contributes to resolution by a small margin.
Black Label’s bass is little bit rounder, tighter. With XBass on, the difference is HUGE. I’ll talk more about it later!
Side note, iDSD BL is a lot more forgiving than the Original iDSD.
 

Hiss | Volume Knob

If you remember our previous iDSD(Silver) review, we implied Android and Windows not being all the same about sound. While using iDSD(Silver), portable devices tend to have a darker background whereas iDSD BL sounds fantastic on everything. USB or Battery Power, Android or Windows.
Regular iDSD was doing some channel imbalance between volumes 0-30%. It wasn’t a big problem because of the gain modes and iEMatch wouldn’t let you to listen below 50%. Actually it wasn’t a problem at all. It was just a fact. The exact fact remains same with iDSD Black Label. We hoped that they fixed this slight discomfort but I guess it’s related to analog attenuator they’re using. Anyways, the problem persists but like I said this is not a game changer or an unfortunate loss.
20161222_024018.jpg

Soundstage | Separation

iDSD has a wide soundstage. Not very tall, but wide. iDSD BL’s separation is a little better than the regular iDSD but still it is the weakest point of iDSD compared to more expensive systems. (LPG, Hugo etc.) I’m not saying that the separation is bad, I’m just saying everything iDSD gives is beyond its price range, except its separation. Its separation has nothing special but it is surely good for the asking price.
20161222_023140.jpg

XBass+ & 3D+

iFi really did fix the switches, the change is NOT subtle anymore.
Let’s talk about the “XBass”. It will be the new favourite of bassheads. iFi really outdid themselves on this one because this switch boosts the low end A LOT. I don’t have the required equipment to measure it but I can say that it acts like a 8-9db bass boost. It’s much much better than the Original iDSD’s bass boost which was very subtle.
Now, the 3D+ switch. Well to be honest I did quite a lot experiment on this switch and I am quite sure that it narrows the soundstage and increases perception of depth when used with IEMs. It is quite different with near-field monitors though. It organizes the stage resulting in more precise and holographic staging. I wouldn’t use it with all IEMs though.
20161222_024559.jpg

 

Driveability | ECO – NORMAL – TURBO | Usability

iDSD is a beast in this subject and that’s probably why it has so many fans. It can literally drive anything. In ECO mode, sensitive monitors, in Normal Mode, standard headphones and in Turbo Mode it can drive most power hungry cans.
  1. Turbo mode 10.0V/4,000 mW @ 16 Ohm
  2. Normal mode 5.5V/1,900 mW @ 16 Ohm
  3. Eco mode 2.0V/250 mW @ 16 Ohm
According our tests, it takes 12 hours to drain iDSD in ECO setting while Battery Mode is activated. On USB Power setting, the battery won’t drain itself whether it’s in ECO or Normal setting. I’ve also tested it in Turbo setting. It approximately takes 6-7 hours to drain its battery.
 

 

Digital Filters | Analogue Filters | Polarity

When it comes to digital filters iDSD has, such as Standard, Minimum Phase, Bit-Perfect, I wasn’t able to hear a noticable difference. If I heard it, I’m not even sure it’s not placebo. The way I understand it, when you’re listening DSD, digitals filters turn into analogue ones.
When it comes to analog filters such as Standard Range, Extended and Extreme, I was able to hear clear differences and I liked what I heard. When you’re listening to DSD, these analogue filters get activated. Also iDSD has a polarity switch. Like the digital filters I wasn’t able to hear much difference.
 

 

Built-in iPurifier

iFi integrated an iPurifier technology onto the PCB of the BL. Right off the bat, I didn’t think that it’d benefit me all that much. Boy was I wrong.. I recently bought a pair of JBL LSR305 for mixing purposes. Using LSR305s with my gaming desktop rig + Dragonfly v1.5 caused crazy amount of buzzing, hissing and RF. God, all that interference… I couldn’t stand it. I’ve been searching for a cure and then iFi sent the iDSD to me. Of course I instantly remembered the integrated iPurifier, I gave it a shot and the LSRs were DEAD SILENT. Truly amazing. All that interference from my GTX 1070, power supply and unshielded motherboard was gone as soon as I plug the BL in. I love you iPurifier. I truly do.
 

 

iEMatch

iEMatch is a passive attenuator that increases output impedance of the 6.3mm out a little. iFi doesn’t have a detailed explanation about how much it changes the output impedance but I assume Off <1 Ohm, High Sensitivity ~ 2 Ohm, Ultra Sensitivity ~ 3 Ohm.
You may ask, “What output impedance affects?”. The general use of this that iFi thought was eliminating the hiss of very sensitive monitors. But it does much more. Output impedance changes the frequency response of an IEM or a headphone. There is a basic calculation for that. If the impedance of the headphone/IEM is at least 8-10 times bigger than the amplifier’s output impedance, it won’t change the sound. If it’s less than that, you may need to greet with a colored sound which may be nice or sometimes unpleasant. I really love the idea of having this switch on a device and it does its work very well.
 

 

[size=17.03px]Male USB A | RCA Out (Direct/Pre-Amplifier) | SPDIF IN/OUT[/size]

Having a male USB A 2.0 connector for the digital connection was a great idea. When you’re going to connect the device to a phone, all you need is an OTG cable and you’re good to go.
iDSD also has a RCA output section. You have two different choices for that. Direct or Pre-Amplifier. Direct, as the name indicates, directly gives the DAC’s reference sound. Pre-Amplifier’s sound is more colored compared to Direct mode. It is warmer. Volume knob, XBass and 3D works with it. 3D that comes from RCA outs are different than 3Ds you’re using for headphones. They have a different circuit iFi says. 3D that comes from Pre-amplified RCAs are called “3D for Speakers”.
Also Direct or Pre-Amplifier, RCA’s are working simultaneously with the headphone output.

I’ve also had the pleasure of testing the SPDIF input, Toslink. I felt a little difference between USB input. Between digital audio transmission methods, the change is always subtle like this was for me. Toslink has slightly smoother but less detailed presentation than USB but in a very subtle way.
20161222_024305.jpg

Installation | Updating iDSD | Smart Power

When it comes to DACs, installation time and progress matters very much. With a Mac OS, IOS, Android or Linux, iDSD is just a plug-and-play toy. There is no installation. If it is a portable device, to make it work in the Battery Power Mode, you switch iDSD on, then you make the USB connection, if it is a non-portable device, you plug iDSD in and switch it on. That’s it. Cannot be simpler.
If it is Windows, there is a 2-3 minute driver installation progress. Download from iFi’s website, install and you’re good to go.
Unlike most of the DAC or DAC/Amp brands on the market, people of iFi are busy with developing new stuff. There are many software versions of iDSD BL Micro. Currently, they are on version 5.2. They do care about your device and continue developing it with softwares. Version 5.2 has a playback delay problem. iFi pointed out that it was related to Sleep Mode. To solve this issue, they published 5.2B. 5.2B doesn’t switch to the sleep mode. They are calling it “the portable version” but I like to call it “the life-saver version”.
iDSD has a Smart Power feature. If your phone battery is about to be drained you can use iDSD as a power bank. iDSD has 4800mah battery that can be used for that purpose which is more than enough for your phone or your tablet. It gives 5V / 1.5A which is quite standard. This feature is another plus if you ask me.

Quick Comparisons

vs. Lotoo Paw Gold ($2000)
LPG has a better resolution, separation, deeper soundstage and it is easier to carry around. iDSD has a wider soundstage.
Tonality-wise, LPG has a sharper imaging and a punchier sound because of its energetic upper mid region, iDSD is warmer because of its midbass and mid forward presentation.
 
vs. Chord Mojo ($599)
Mojo is warmer, it has a narrower stage and it is more intimate. iDSD BL has a more balanced sound compared to Mojo. Resulting in better detail revealment. They are both very musical. BL has superior resolution and soundstage. I’d personally go with BL. (Device size is real though, you may need to evaluate that matter in your mind first)
 
vs. Audioquest Dragonfly Red ($200)
Audioquest have a similar sound signature. It’s not as detailed as iDSD. iDSD have better PRaT and handles complicated passages more successfully. iDSD has more natural timbre.
Red sounds kind of thin, especially with classical music. iDSD has more bass weight.
 
vs. Audioquest Dragonfly Black v1.5 ($100)
Dragonfly Black has a lot less treble extension.Technicality-wise iDSD has a better resolution, detail, separation and soundstage. When used without a Jitterbug, Dragonfly is more likely to hiss.
 

Summary

iDSD BL is the definition of bang for the buck in every way. More or less expensive, there aren’t many options other than Mojo. Furthermore, iFi is a concerning company, they care about you, also they care about their product, iDSD’s resolution is very good and it can literally drive anything. It has tons of features and I think iDSD BL is the real deal.
If you are looking for a DAC/AMP between 350-750$ this is your safest bet. Go get one!

I am seriously considering one but i am afraid of the channel imbalance at the lower side of the pot because i do plan to use some sensitive IEMs with it too. so far i have seen people say it's not an issue at all to very apparent...which is really not helping :D. What would you say about that?

100+ Head-Fier
Pros: Lots of inputs and outputs, great features, delightful sound quality
Cons: Ridiculous USB type-A input, excessive size/weight for portable use, too many switches in too many places, loud POP! on power-up/power-off
First, I'd like to thank Lawrence and the folks at iFi Audio for lending me a micro iDSD Black Label DAC for a week so that I could experience it firsthand. If you're reading this review, I'm assuming you fall into one of three categories:
 
  1. you have an iFi DAC and you're wondering if the micro iDSD Black Label is a worthwhile upgrade
  2. you're in the market for a transportable DAC and are curious about iFi's new flagship product
  3. you've followed a link to this page but otherwise, have no idea what this thing is about
 
iFi Audio is a brand that requires little introduction here on Head-Fi, but in case you missed the massive crowd design topics in this forum that are associated with the micro iDSD, I'll provide a brief introduction. iFi Audio is a subsidiary of AMR (Abbingdon Music Research), which is one of the UK's largest manufacturers of high-end audio systems. AMR is famous for their Series 77 and Series 777 products, including the highly regarded DP-777 reference class DAC with NOS tubes. For the performance it provides, this 25.4 lb monster is a great value even at its lofty $5K USD price. The problem? Well, apart from cost, it's not very portable!
 
In the US, the assembly of gear that renders sound into a room is commonly referred to as a "stereo", even if many more than two channels are enabled. The term, "high-fidelity" is an adjective that describes the quality of a stereo. In the UK, the reverse is true; the term "hi-fi" is a noun, not an adjective, and "stereo" indicates the number of channels supported by the hi-fi. You go to your UK friend's house to listen to their "hi-fi", not their "stereo."
 
The name "iFi", then, is a personalized version of "hi-fi". Like that certain American company that is keen to put the letter "i" in front of lots of nicely packaged products, "iDAC", "iDSD" and similar names indicate that these are personal entertainment products with trickle-down technology from AMR. Think of iFi Audio as the "personal hi-fi" (or "i-fi") arm of AMR.
 
Ignoring their Pro and Retro lines for a moment, iFi Audio's components come in two sizes: "nano" and "micro". These sizes share the same six-sided cross-sectional dimensions of roughly 2 1/2" wide by 1" tall, differing only in length--3 3/8" for the nanos vs. 6 1/8" for the micros. While too thick to fit unobtrusively into a pocket, these are seriously small components compared to what you'll typically find in a desktop or rack audio system.
 
micro_nano_BL.jpg
 
 
I think of iFi Audio as a one-stop shop for computer audio. In addition to five native DSD-capable USB DACs plus a USB to S/PDIF interface, their product line has the greatest depth and breadth in USB power and signal clean-up devices on the planet...by a huge margin. Their emphasis on purifying the power that is fed to the DAC is particularly telling--it indicates that iFi Audio has a deep understanding of how and why clean power is important to computer audio, and that understanding drives their product design and product enhancements. The most recent product to benefit from this understanding is the new micro iDSD BL.
 
BL_Box.jpg
 
Those familiar with the original micro iDSD DAC/amp will find nothing new in terms of function and features with the Black Label model. All of the switches, toggles, inputs and outputs have been duplicated in the new product. The micro iDSD DACs come nicely packaged with a black velvet pull string bag, USB type B to A adapters, USB extension cables, RCA cables, a short 1/8" TRS patch cable, a TOSLINK S/PDIF optical coupler, a gold 1/4" to 1/8" TRS adapter, and elastic bands to strap the DAC to a smartphone or portable player. My original micro iDSD kit also included a set of stick-on rubber feet and a pair of thick plastic spacers to keep the DAC and whatever it is strapped to from scratching each other. I have found the rubber feet to be handy on my micro iDSD to keep it from marring the table or sliding around, but the rubber feet and the black velvet bag are somewhat mutually exclusive, so I can see why iFi dropped them from the BL's packaging. They are easy enough to find at your local hardware store if you want them.
 
You might never know it by just glancing at the iDSD BL, but it sports three digital inputs (USB, TOSLINK and COAX S/PDIF), one analog input (1/8" TRS), one digital output (COAX S/PDIF), and two analog outputs (1/4" TRS and RCA, fixed or variable), plus a USB charging port. That's a crazy amount of I/O for such a small device! Think of the iDSD BL as the personal audio equivalent of one of those big, fat pocket knives with a dozen or two different tools. I actually tested all of these inputs and outputs, and they all work as advertised. What's interesting is that the COAX S/PDIF output functions even with the DAC switched off. As expected, there's no signal on the COAX S/PDIF output with PCM material at sampling rates above 192kHz or with DSD. The only thing missing is conversion of the analog input signal to digital on the USB and COAX S/PDIF outputs. :)
 
BL_Inputs.jpg
 
The combination of Power Mode and iEMatch® switches provide, in theory, nine different gain settings; however, iEMatch® is likely intended to be used with Power Mode set to "Eco", so effectively, there are five different gain settings. These are important because both versions of the micro iDSD have volume tracking issues at settings below 9 o'clock. Used together, these switches should enable just about any headphones to operate comfortably at close to the optimal 3 o'clock volume setting.
 
The sound can be tailored using the X-Bass®, 3D Holographic Sound®, Filter, and Phase switches. I always felt that the effect of the 3D switch was a little too heavy-handed on the original micro iDSD; however, it seems to be more pleasing on the iDSD BL, making it usable even without the X-Bass switch enabled for most music. My understanding is that these switches have a different effect on the RCA line outputs when the preamplifier mode is engaged, providing enhanced stereo separation in the bass. I did not test this for reasons that I'll explain later. Like all of iFi's other DSD-capable DACs, the behavior of the filter switch depends on input format. Normal and minimum phase are digital oversampling filter settings with different cut-off frequencies, and bit-perfect is a non-oversampling setting with no digital filter. The same positions affect the cut-off frequency of the analog filter for DSD. The phase switch is a nice addition, however, although I'm somewhat sensitive to absolute phase in my loudspeaker + room system, I've never been able to identify a difference by inverting phase while listening with headphones.
 
The light on top of the DAC changes color to indicate the source format. I wish that the micro iDSD models used a color scheme that's more similar to the nano iDSD and micro iDAC2. On the latter, green indicates a CD/DAT sampling frequency while any other color indicates high-rez. This is a useful distinction that's lost with the micro iDSD models which illuminate green for anything at or below 96kHz.
 
A more significant point against the micro iDSD models relative to their less advanced siblings is the loud POP! that is emitted from both the headphone and RCA outputs when the device is switched on and sometimes when it's switched off and goes in/out of standby mode. I was disappointed when I discovered this issue with the original micro iDSD and even more disappointed to find that it has not been corrected in the iDSD BL. Not only is this POP! somewhat painful if you switch on the DAC while wearing efficient headphones, it precludes the DAC from directly driving power amplifiers and powered monitors. It can be a problem even if great care is taken to ensure that the external amplifiers are always off or muted during DAC power transitions because going into or waking up from standby can also cause an output surge. While not expensive, at the ~$500 USD price-point, I expect an audio product to be more well-behaved. This is why I did not test the preamplifier feature on the iDSD DACs.
 
My final gripe with the crowd designed micro iDSD concerns the USB type-A input. Oh my gosh is this irritating! The idea is that the DAC will be directly connected to a smartphone or tablet by way of an OTG or camera connection kit cable, making the combination a tidy digital transport+DAC+amp combo for music on-the-go. Even though the type-A input eliminates the need for a short USB cable, this is an awkward and un-pocketable contraption. What's worse, we now have a ~$500 DAC that is incompatible with standard audiophile USB cables like iFi's own Mercury and Gemini, even though the DAC is sufficiently resolving to benefit from using them. We're left using a low-quality adapter or springing for the type-A iPurifier2 (which I did not have on hand for this review) to connect the micro iDSDs to a PC, which for a DAC this size and weight is likely the more common use case. Frustrating! A type-A input would almost make sense on the smaller nano iDSD models, but, in my opinion, it has no place on the micro iDSD. Okay...end of rant!
 
Moving on from form, features, functionality, and my personal gripes to what you're probably more interested in...how the iDSD BL sounds. In a word, "lively". The BL departs slightly from the signature iFi Audio "house sound", which I would describe as erring on the warm side of neutral. Compared to previous iFi DACs, mid-bass on the BL has a little more punch, and vocals soar with a more open, forward midrange. Highs are, in particular, more extended, airy and pure than the iDAC2.
 
loft_wide.jpg
 
This new DAC is fast. I mean, crazy fast sounding--if that's even an audio descriptor. Listening to acoustic guitar, you get the sense that the DAC is tracking each string and the associated harmonics with tremendous speed and accuracy. No details are lost. Attacks emerge from the soundstage like a flash of lightening, and decays extend like rolling thunder into a deep black background. The more forward balance of the BL brings alluring presence to vocals but also to strings, snare drums, and brass instruments. The sound is energetic, punchy, and engaging both in the big rig and with headphones.
 
Switching back to the original micro iDSD, I noted that the presentation is more laid-back and euphoric while still maintaining excellent detail. Soundstage width, depth, and height seem to be slightly greater with the original iDSD while the BL's soundstage is tighter and has a tiny bit more focus. The iDAC2 fits somewhere in the middle with a big, enveloping soundstage and lovely midrange bloom. It falls short relative to the BL only in its treble presentation, which by direct comparison, sounds slightly colored and rolled-off (both DACs using the minimum phase filter setting) vs. BL's pure, airy highs. This difference is most noticeable in acoustic jazz cymbals and hi-hat.
 
micro_iDSD_BL_Orig.jpg
 
 
Others have covered in detail what iFi has changed internally to bring about these sonic improvements, so I won't repeat them here except to say that the new Panasonic OS-CON capacitors should receive much of the credit. They are probably also responsible for the longer than normal burn-in time associated with the micro iDSD BL--this thing should finally settle in sonically after about 400-500 hours of playback.
 
All three of these "micro" sized DSD capable DACs from iFi Audio sound terrific, especially considering their relatively low $350 - $550 USD price range. While there's not a huge difference in sound among them, each clearly has its own personality. If you delight in excavating every last micro detail from your music and listening sessions, the new BL is going to be your favorite by a mile. You might prefer the original iDSD if you prefer to just kick back and veg to soothing music with an enveloping soundstage while occasionally digging on details buried in the mix. If you don't require the portable features, the iDAC2 is incredibly resolving and punchy without being fatiguing.
 
Your choice among these three may come down to system synergy as well. Listening to the BL with Grado RS2e headphones was an intense experience that could easily become overstimulating and even fatiguing depending on music choice and listening duration. However, the more laid-back Sennheiser HD600s were a delightful match to the BL's liveliness. In the big rig, if your system's balance tends towards forward or analytical, you may find the BL's intensity to be exhausting (perhaps addressable by inserting iFi's micro iTube between the DAC and your amplifier). However, the BL will add a little extra snap to systems with a more relaxed presentation. My big rig system employs room treatments and digital room correction, so the presentation is among the most neutral I have ever heard. As such, I never found the lively, energetic nature of the BL to be fatiguing, and I missed the beautiful, extended treble when I switched back to my beloved iDAC2.
 
If you own the original micro iDSD, is there enough difference to justify the upgrade? It really depends on your listening priorities and associated equipment. If you have a dedicated audio PC with high-quality media player (JRiver, AMARRA, Audirvana, etc.) and Sennheiser HD600 or better headphones, you'll definitely appreciate the improvements in presence, detail, and speed offered by the BL. If you're mostly driving the DAC with a smartphone and using IEMs, the differences may not be as apparent or easy to appreciate. The BL is a pretty big step up in sound quality and power from the nano iDSD models, but keep in mind that it's also much larger, heavier, and less portable.
 
The Chord Mojo is now the same price as the micro iDSD BL, so you might be wondering how to choose between these two. I happened to have one on hand for this review, so I did some quick listening comparisons. The difference in sound is nearly as great as the difference in size! Considering form factor alone, the Mojo is the way to go if portable audio is a priority for you. It's small, dense, and ergonomic. It has a pair of headphone jacks for sharing music with a friend without a splitter. While I don't love the mini-USB input, at least it's possible to find both OTG and audiophile grade USB cables with mini-USB plugs, including some from Audioquest. The Mojo's sound is even more laid-back, "British", and warm than the original micro iDSD, so the contrast in presentation between the Mojo and the BL is quite stark. Carefully consider your choice of headphones and associated gear before choosing one over the other. Both are beautifully detailed in their own way, but the BL presents a blacker background with greater dynamic contrast and is my pick between the two for best value for money.

While I do miss some of the benefits of the BL in my system, I'm eagerly looking forward to seeing if iFi will give the iDAC2 the Black Label treatment. If so, that could be a very exciting sounding DAC that will be a welcome addition to an already extremely impressive lineup.

Fair question...I picked that up during a conversation with Mr. Zero Fidelity himself, Sean Fowler.

I never noticed the pop on power up with my iDSD Micro Silver.  I did notice it with the Black Label.  It isn't that unusual.. I think it indicates lack of a muting relay that would add cost/complexity and is one more item in the signal chain that isn't absolutely necessary.  
 
Via my Audeze LCD-X headphones, which, for Audeze, are high sensitivity with very easy to drive low impedance, the thunk was merely just an annoyance.  Not anywhere near loud enough for me to be worried about any possible damage to downstream components. 
 
It may be more inconvenience, but if it truly worries you, keeping your headphones unplugged until after power on is a workable solution.  I will also note this only happens via the headphone output.  No such thunks on the RCA outputs (at least not in fixed mode)
 
I agree about the increased presence and air.  It is especially welcomed (being done in a quite tasteful amount) in the upper mid lower treble.  Everything has just a bit more life and sparkle.  But I still would not go so far as to characterize the BL as bright.  Actually, as we move on up into the treble the sound is very smooth, sweet, and grain free.  No hint of listener fatigue. 
 
Back in 2014 I had a discussion with Thorsten Loesch about the USB type A input.  My concern at the time was possible compromise in fidelity when using the Gemini cable.  The extra cable or adapter seemed to be a potential weak spot where any gains achieved via separation of the power and data feeds could be lost.  Thorsten didn't seem to think the difference would be significant, and I am guessing their lab measurements showed little actual difference.  But that is just a guess.  For me the biggest issue I have is the clunkyness of the heavy aluminum termination on the Gemini cable combined with the added length and weight of the iPurifier 2 and/or the required adapter.  All of those combined together plus gravity puts quite a downward strain on the connector.

I still contend that the loud POP effectively renders the preamplifier output function of these micro iDSD DACs useless for those who otherwise might consider connecting them directly to powered monitors or poweramps. Disappointing also since the much less costly iFi nano iDSD DACs do not seem to have this issue. Obviously, iFi knows how to build a device that does not emit a huge "POP" upon power-up or wake-up from sleep, but they didn't bother for their flagship micro iDSD models. Like the type A input, I'll continue to complain loudly until I feel that I've been heard.  :)
 
As I said, how the BL sounds really depends on the system in which it operates. With the Grado RS2e headphones, it sounds bright (trust me), but it was delightful with the Sennheiser HD600's and totally fine in my Legacy Audio FOCUS SE based big rig.
 
 
Your note about the conversation with Thorsten is helpful; however, the adapter is still appalling. I agree with you on the weight issue as well. Again, going with a type A (or micro USB) input almost makes sense with the ultra-portable nano iDSD products. I personally think it was a terrible choice on the larger, heavier micro iDSD models. This is the sort of thing that sometimes happens when something is designed by committee, sadly.

You can expected the improvement in power supply to provide a clean and good support to the DAC circuit.
A Black outlook let it looks cool and much high class than the original silver color.
 
Thank you IFI for let me be one the BL tour in Hong Kong. My BL was totally new in box . I opened it from the box and hear its sound from zero run in .
 
Talk back my setup with the BL.
My setup was a transportable headfi setup. A DX50mod with coxial out to BL . A Venture 4 core Coxial cable was connected between DX50 and BL.
The BL as DAC with direct mod , RCA out to my DIY AMP , A 8 core pure silver RCA cable was connected between BL and AMP.
The IEM I used was IE800 with Earmod , 8 core pure silver cable used.

20161229_114425_HDR.jpg
 
 
BL provided lots of solution for me such as PC with USB connect to BL , DX50 coxial out to BL and use BL own phoneout for my IE800 , and my transportable setup , DX50 > BL > AMP > IE800.
 
BL support DSD with its USB but cannot support DSD with coxial input. I have try some players with coxial out but BL cannot playback the DSD with coxial in.
 
BL has powerful AMP inside, even IE800 can drive well and muscial . the bass+ and 3D+ effectted with more bass and better sound stage.
 
I used BL as DAC for my AMP. It was a musical DAC , Warm sound with good punch. Its same style with the old IDSD. Since my BL was new in box , the sound with tight, the dynmic range, Treble extend and Bass punch was not as good as the old one.
The old IDSD was demo at shop , maybe the run-in time not enough let BL as good as the old one. The good news run-in was improve. The BL at last when I return , it was better than before but still not as good as the old one. But I believe the BL will better than the old model as new BL change lots of capacity as they need run in as well.

Even with the somewhat-inefficient Beyer T1.2s, the amp in the iDSD is overkill.  I still run the iDSD on eco mode with the T1.2s.  I'd say unless you're looking for a portable unit that can power the HE-6, you'll never use all the power that the iDSD can output.  Headphones now are becoming more and more efficient every day.  The ability to do DSD is nice though, and something I definitely miss with the Dragonfly.

@jsplice You must have more sensitive ears than me, or have a much lower preferred listening level. I listen at about 78dB and the iDSD BL needs to be in Normal mode to drive my HD600 adequately. The Beyerdynamic T1s are more demanding than the HD600, so I have to wonder if you are actually driving them fully. I'd turn the BL to at least Normal (I wasn't a fan of Turbo as noise shot up)--but if your listening level is really low you might get channel imbalance--and see what the headphones sound like.

@glassmonkey I haven't measured the db level after I've set my listening level, so I can't say where I'm at there.  I've also never used the iDSD with the HD600 so can't make that comparison.  Yea, I've got the channel imbalance thing before when having the volume set low in normal mode.  That's the main reason I've kept it in eco.  Also, the Elear are so efficient that there's no way in hell I can use normal mode with them.  Even on eco mode with the Elear, I can't really get the volume past 10 o clock.  I will probably end up keeping my Dragonfly Red instead of the iDSD if I stick with my Elear and get rid of the T1.2.  If you have super efficient headphones, the amp in the iDSD is just overkill IMO.

MOT: Double Helix Cables
Pros: Abundant power, stellar DSD performance, wide-ranging features to customize the sound
Cons: Stretch-limo dimensions (narrow and long), 6.3mm output only, unusual USB input
First off, I want to thank Tim @ Kitsune Hifi who sold me on iFi gear and gave me good advice on improving the digital end of my system (between the transport and the DAC), which was sorely lacking.  However, the iDSD BL could probably stand in for my home system, and at times makes me forget I even have a giant, overcomplicated rig.  
 
Pre-disclaimer: I never write reviews and this will be a quick early one - some first impressions and my gut instincts on it - don't expect anything hyper-analytical, just some macro level stuff.  
 
First impressions:
This thing is long and narrow, while it's not for pocket use, it's not going to take up much room on the desktop, just place it judiciously.  It still takes up less area than a Chord Hugo, while clocking in at 1/5 the price.  It is made of hefty aluminum and the switches and knobs feel solid.  It has some heft to it, and the internal photos show a menacingly dense set of boards and exotic parts.  iFi does their own totally custom opamps, the digital clocking comes courtesy of their AMR ultra high end brand, and there are some badass caps and resistors in there for sure.  It's based off the new TI DSD DAC chips, of which it has two.  While you're going to have to make some adjustments to your hookups if you have all balanced stuff, it's well worth it.  
 
Features: 
The bass boost and crossfeed 3D toggles are subtle and don't seem to detract from the experience.  Not annoying me is a good sign, I left them on at most times, especially with the Utopia which can always use a little help to max out its bass capabilities.  The three different filters toggled on the side will take some experimentation and vary in their function for different filetypes so you can have hours of entertainment working out how they stack up.  With three different gain settings, I found that the Utopias do not need the high gain level - the Black Label seems not to flinch at really any of my mountain of headphones, even the hard to handle LCD4.  There are further IEM modes that can be activated to really dial things back and impedance match so it was able to play nice with my various CIEM.
 
Sound:
The iDSD has a male, recessed USB-A in the back panel; the included USB 3.0 cable has a cable mount female on it that slots into the recess.  I'm not going to think too hard about what iFi was going for here, nor am I going to agonize over the best way to hook everything up; copious adapters are included to make sure all avenues are covered.  I just plugged it into my Holo Audio Titanis USB Turbo to further clean up the Macbook's USB output, plugged in my Utopia, and that was what I spent the most time with.  I was really floored flipping through my DSD library (which has been dormant due to my use of the Yggdrasil, but is about to change with the impending arrival of the Holo Spring KTE Edition DAC, which will go head to head in my audio lab rig) as I think even on my home setup I've been missing out on some really insane little details using the Utopia - and this setup is by no means burned in or hooked up to an external amp.  I'm basing this all on about 4 hours listening tonight and on-off listening in the past week.  Loads of power and dynamics, ultra tight bass, and minimal fatigue.  I'm honestly laughing in horror at what i've spent on a gaggle of other portable dac/amps and DAPs.  They're all going to be spending a lot of time on the shelf.  If thieves showed up for the rest of my rig, I wouldn't even be that put out, so long as I had the Utopia or the Z1Rs and the iDSDBL.  The big thing is the dead silent background due to how well implemented the digital end of things is; pair that with the well-above-average power output and the relative efficiency of the Utopias, and they feel like they are being pushed hard even on medium gain.  This little dac/amp gets out of the way and lets the Utopia do their thing, while playing nice with literally every file format, even ones for which there are no files yet (DSD512 lol).  DSD256 classical is just fearsome, I don't even know what to say there, except it's a new level of delicate, nuanced clarity.  The free Mozart violin concerto on 2l.no should be a must have in everyone's test rig, with amazing transitions between the most quiet tiny bits towards the periphery of the soundstage exploding into the full orchestra, and each instrument placed laser-like in the headstage.  At this point in my audiophile career I have a ridiculously short attention span, so the fact that this new toy is not in a drawer somewhere yet is a testament to its value to me.  It's a keeper and at $550 should be on everybody's desk.

Verdict: 
Give it a try - in the very least you can feed your favorite amp with it, use it as a preamp, and everything in between.  iFi does not mess around and this is a disruptive product that has a no-holds-barred assault of technology and synergy to let it perform as it's doing right now.  Once I use it for months I might find something to whine about, but for now, it's a no brainer.  The real reason I'm using it is that it doesn't fatigue me with the Utopia, which is no mean feat.  With the wrong amp and dac, they have ludicrous clarity but will drive you nuts with that little bit of extra edge and attack and shrillness.  The only solution is a really good source and source material, and with some good DSD & hires files and the iDSD Black Label, you're all set.  

Disclaimer: I paid retail price for any gear I've bought from Kitsune.  It's worth it to get an extra helping hand on what stuff to try next.  If I really wanted to, I could try to fish around for show samples direct from manufacturers to save a few bucks, not the case here.

Christmas Dacamp with all the trimmings

Introduction

 
I have been lucky enough to be part of a very special tour.  iFi has given me the chance to look at their heavily updated iDSD. They have called it the Black Label Edition. I’m part of a review tour. As reviewers on headfi, we are bound by only 2 things really; we must post a review and we must keep the unit for the length of time specified by the company. iFi gave me 7 days to find out as much as I can about this dacamp. This is the result. Hope you like it. If you don’t I’m sorry. I did my best in the time I had here. I try my hardest to put myself in the shoes of a prospective buyer and I know iFi any other company only want to know what I think about their products. Not what they think. I don’t get paid for this and I’ve done quite a few reviews this year, both on here and on earphonia.com. This doesn’t make my opinion more valid than anyone else’s. It simply shows I’m in this for the long run. 
IMG_20161222_114115160_HDR2.jpg
 
My association with the iDSD is rather short. I used this when I met up with my good friend @glassmonkey on a weekend’s mini meet back last year. I threw a number of headphones at the old model ; the Sennheiser HD800, HiFiMan HE6, Mr Speakers Alpha Dogs were amongst some of my less sensitive headphones. All were powered admirably by the iDSD.  Fast forward to December 2016 and we now have an elegant black number to spend a week with. Micah(aka @glassmonkey) passed it to me last week (it’s a small world isn’t it?) and I have set it off on it’s way with a tearful wave. This is the iDSD but not as we know it. Many things have been changed from the standard model. iFi have moved on since then. Micah has written plenty on the components that have been changed. Suffice it to say, iFi has done more than just a spray job on it. More customisable power but less extreme 3D and bass switching are the order of the day. 
 

Features

 
So what is the BL model and what can the iDSD do? And are these the features you are craving from your source? Or this is overkill for you? When one reads through various threads the impression I get is that there can never be enough spec. Each person has found some aspect of the hifi world that appeals to them, be it DSD or balanced, mp3 or flac. The industry is changing all the time , not necessarily for the better. Many of the changes are to keep up with the changing digital formats available. 200 Gb memory cards are being filled to the rafters with music. These can even fit in some phones, so manufacturers are being forced to get OTG as standard on their units.
IMG_20161222_114041235_HDR2.jpg
 
The iDSD is a Dacamp. It can be fed music from a laptop with it’s high quality USB cable. It can also be fed an optical in signal and output a digital signal through optical. OTG is supported, so phones can output to the Black Label. I was able to use Android Marshmallow natively through Deezer and YouTube aswell as the usual USB Audio Player,  Onkyo Player and Hiby Music Player. All the weird and wonderful formats I had on my Macbook were easily taken care of by the iFi.  The iDSD also accepts analogue signals. The 3.5mm jack by the 6.3mm input, is not as I initially thought for IEMs. To my embarrassment I was informed it was for audio sources without digital out connections to be used on the iDSD. In this way the iDSD will act as an amplifier. The iDSD also can be used as a preamp or direct line out, to form part of a full sized HiFi. The F6 power amplifier I have did not cope with the amount of juice the BL was trying to put into it, so I used the preamp which worked suitable well. The Direct Mode will only be using the DAC part of the iDSD. The preamp uses both. There is a smart charge facility on the side of the unit. This allows for your phone perhaps to get some emergency power once it’s been OTG’d to death. I’m presuming many of you  know this already; even larger newer phones don’t last more than a couple of hours playing OTG out to an external device. The iDSD will easily outlast your phone so should be able to keep it going until you can get to a proper power source. Of course you won’t be using the iDSD as a source by this time and the phone will be all but redundant while it’s trying to achieve more charge. 
IMG_20161222_114102031_HDR2.jpg
 
Within the analogue and digital in realm we have been given a wide range of choices. There are 3 sensitivity switches on the underside of the unit for IEMs. A minijack converter is provided to plug in your earphones to the output. I found the highest sensitivity setting on all the IEMs I tried to be too quiet even with the volume switched to max. The lowest setting was really loud. Wow! There is enormous scope for getting the right balance of loudness setting within those 3 settings. The settings on the side are for full sized. The highest setting was too quiet even for my 32 Ohm AT W1000Z closed cans. The middle setting was perfectly ok for these. The HE6 needed the lowest one but not to the maximum volume.  With the headphones all dialled in for volume, you must then concentrate on the Digital Filter. This is a 3 way switch for Bit Perfect Minimum Phase and Standard. Standard is the most tweaked filter and is designed towards a DSD file. I settled on the standard filter as I felt it added some good punch to the music without making it harsh. All is not over yet. You must decide whether you want more bass in your life. There is just such a switch for this. Maybe your vinyl rips need a touch of extra or your orchestra is not sounding full enough? The bass has an on off setting. The 3D switch will widen the image of your soundstage considerably. Such features are available through various software. For those who will wish to change between filters on various tracks, this as a hardware feature, could be extremely useful.
 

Build

 
With the iDSD comes many bits and bobs.

The packaging is beautiful. The unpacking of the unit was a sensual pleasure. There are things which impressed. A variety of non standard looking cables and stars and bags fell gently out of 2 shiny white boxes neatly tucked into their respective columns hidden under the belly of the iDSD itself.  
Top left - an analogue cable 3.5mm. Coming downwards a USB converter for OTG. The purple cable is twin RCAs for line out to a full size amp. 2 thick rubber straps to tie your phone or DAP up to the BL. The white shiny card above is a spacer to keep the iDSD from being scratched or rubbed by the thing it’s attached to. The blue USB cable is a thick high quality one. An optical adapter, detailed manual and USB adapter complete things. Other than one really nice extra. 
 
IMG_20161222_1136287082.jpg
 
 
A black velvet carry pouch. Very nice indeed. 
A sizeable number of accessories. For OTG the cables provided here won’t do the trick. There would be far too much cabling once even a tiny micro usb is daisychained on. Chord supplied one tiny usb cable for the Mojo in comparison. RHA also make sure they have lots and lots of goodies in their DL1 Dacamp box. I used the Mojo OTG cable from their accessory pack with the iFi which created a great little stack for out and about. I would have liked to have seen a dedicated optical cable with the bundle. Adapters are very easy to lose. 
There has been some discussion about the volume control on the iDSD. The original volume control was slated by a vociferous minority for being unbalanced at low volume settings. The volume has not been changed on the BL version.

It still has issues with unbalanced sound at low volume. It’s therefore extremely important to get the switching sensitivity correct to alleviate this problem. This problem does not exist on either the RHA DL1IMG_20161129_113738013_HDR.jpg
 
or the Mojo.

Sound Quality

 
I have a semi professional analogue to digital converter, the ART Phono Preamp Plus. It’s ability to rip vinyl without electronic interference in the background recording is the reason I bought it. I soon discovered it had many other benefits. I can hook up any line out source, in this case , the iDSD, and record the output straight into the ART and then onto the MacBook digitally. It’s merely a case of picking a track , plugging the device into the back of the ART and pressing record on Audacity.  Only the source is changed. switching is instant.

Once a volume match is attained, my Chord Mojo can then be compared side by side, over and over again, using the same track, same input, same volume. This testing was done by me on day one. They are freely available for anyone who wishes to listen for themselves. There is no load going into the 2 devices. The analogue stage and the quality of the preamp mean that the sound quality is not as good as you would get from plugging your headphones straight into either device. It will give you a flavour of any differences between the Chord Mojo and the iDSD Black Label. In my opinion the differences are there. Please PM me if you wish to be sent a link to them. They are of a DSD recording so should be pretty good quality. I invite you therefore to listen for yourself as to what you might think of the sound quality of the iDSD BL. If you wish to do that I would encourage you not to read any further. STOP NOW!

PM me and I will send you the link. Make your own conclusion, listen as much as you can stand, then come back here and see if you agree with me. I really hope some of you do. I am not the authority here, nor are my ears. We all must decide for ourselves using the information out there whether any audio product will suit our needs and improve on what we have. Only the individual can decide that, ideally with an audition. This is the closest I can give anyone to that experience. You are welcome!
Now it is time for the spoiler, my own opinion of the iDSD sound quality , specifically against 2 devices.  Device one, from memory. The iDSD v the RHA DL1 dacamp.IMG_20161129_113658868_HDR.jpg
 
The iDSD is a clear winner against the DL1. I found the RHA to be too shrill in the upper regions and too bloated in the lower regions. This with one notable exception; the CL1 Ceramic IEM in balanced mode  was superb through it. The iDSD v the Mojo; that you can hear for yourself. You can take my opinion with a pinch of salt. For what it’s worth, I did like the iDSD a great deal. The standard filter and mid setting on with the bass and 3D switch off sounded powerful and punchy. It sounded a little thin and slightly recessed in the mid section and less strained in the treble regions than the Mojo.mojorha4.jpg
 
The bass and subbass lacked some of the impact of the Mojo. Although the Mojo was probably slightly more rolled back in the higher FR the iDSD seemed like it was being pushed slightly harder. I have had the Chord Mojo since October 2015. 
 
Clearly it will take quite some beating. I haven’t yet found a portable device that I preferred the sound to. These differences in SQ are not huge differences. I am subtly trying to defend my views on the differences between the 2 if you are unable to hear them. I am merely stating that buying a different pair of headphones would give you a much more obvious set of differences than changing between the iDSD or Mojo. 
 

Conclusion

 
The iDSD BL offers an awful lot of options for the money. It costs more money for the Chord Mojo. The Mojo is a simple device with few options. It can output 2 headphones simultaneously whereas the BL  only has the one. It has arguably better sound quality than the iDSD but the differences are small. It fits a standard 5” smartphone or DAP considerably better than the Mojo without it’s adapter, although for the same money the Mojo has an accessory pack which sorts this problem out.  All choices in the audio world are complicated. If I had my opinion as to which device I would spend my money on, then I would choose sound quality before all else.

In this regard I would put the iDSD a close second to the Chord Mojo. But, my dear reader, have a listen to the track which I have painstakingly prepared for you. Click here You may have an entirely different take on the matter

@gunwale  the differences to me are quite clear but I have cheated a little by listening many many times with everything from $20 IEMs to AKG K1000s. If you aren't noticing the differences then I don't think you need to spend so much money on stuff like this. The money might be better invested in different headphones as they are much easier to pick up the differences on. It's a blessing for you that you are not hearing the differences, or perhaps, imagining the differences.....

New Head-Fier
Pros: Smooth delivery of orgasmic sound. Powerful enough to drive a planar, whilst gentle enough for sensitive IEM.
Cons: xBass+ can get a tad bit too heavy.
I will be comparing both the iDSD and the iDSD Black Label (called BL for short) with the XBass turned on as default as that is what I am used to listen. Each unit will be given a rating and at the end, the highest score wins. For a consistent result, I will be using my Hifiman HE-560 and 64 Audio U10 UIEM with Effect Audio Ares cable. I will not be swapping too many gears in order to not create too many variations. An ABX tester will be used so I can switch between the unit easily. All songs are ripped as AIFF from cd's. I will leave my thoughts on the stack integration and other headphones at the end. Do note that with your gear YMMV.
 
  • Counting Crows - Big Yellow Taxi
    1. Immediately, with the harder and punchier bass of the iDSD BL, I thought this song had a clear winner. Vocals were thicker, more musical, and by the mid of the song, I was tapping my feet and bobbing my head. Further switching between the 2 units made me realise that although the bass on the iDSD was not as punchy, the guitar strum just before the chorus sent chills down my spine thanks to its brighter treble. A thing to note is that while the HE560 liked the bass boost, but the low end got a bit too boomy for the U10 IEM.
    2. iDSD - 4/5 | iDSD BL - 4/5
  • Eagles - Life in the fast lane
    1. My gripes previously was that the bass is too light on the track with the iDSD. Now though, the iDSD BL presents a harder bass kicks in the opening, overall enhacing the imaging and musicality of the song. XBass and 3D is an appropriate option to use as it carries the song up to another level - closer to the live experience.
    2. iDSD - 3/5 | iDSD BL - 5/5
  • Norah Jones - Crazy
    1. The iDSD BL brought Norah Jones directly to my room. The darker Black Label makes her voice sound as smooth as honey. Her voice just tickled my ears bringing me to a huge grin. The notes from the double bass and piano was well rounded and punchy which added some depth to the sound.
    2. iDSD - 4/5 | iDSD BL - 5/5
  • Babyface - Change the World (w Eric Clapton)
    1. The leaner iDSD takes the cake here due to the airy presentation. It brings out the details in the choir, hi hats, the electric piano and the bongo. I had to turn off the XBass on the BL as it was covering the detail in the song passage. Marks to the brighter iDSD.
    2. iDSD - 5/5 | iDSD BL - 3/5
  • Joe Hisaishi - My Neighbour Totoro Opening theme
    1. Again the airier iDSD beats the iDSD BL in this song. You can hear every instrument clearly thanks once again to the more neutral presentation. I tried adding in the 3D setting, while better, it could not sound as clear as the iDSD.
    2. iDSD - 5/5 | iDSD BL - 3/5
  • The Blue Hearts - Linda Linda (J Punk Rock)
    1. the iDSD can make the treble slightly splashy but more detailed. The iDSD BL controls the song better but could be duller in presentation.
    2. iDSD - 4/5 | iDSD BL - 5/5 
  • Aerosmith (ft Carrie Underwood) - Can't stop loving you.
    1. The brighter iDSD emphasises the guitar strums but it can get a bit fatiguing if you are sensitive to high frequencies. the iDSD BL tames the highs and adds more depth to the song. However, Carrie Underwood's voice seem to be very slightly muffled due to the darker sound signature. the iDSD projects her voice and overall instruments better.
    2. iDSD - 4/5 | iDSD BL - 4/5
  • Scars - James Bay
    1. The iDSD projects James Bay's voice better, but lacks the depth that the iDSD BL provides. The bass kicks can get slightly boomy with the xbass turned on. The level of detail for both units remain excellent however.
    2. iDSD - 5/5 | iDSD - 5/5
  • AC/DC - Hard Times
    1. iDSD BL has got this song in its grip. The darker signature gives depth and really brings out the hard rock genre of this song. Hi-hats are well controlled but still remaining detailed. That Gibson electric guitar just sounds so rich with the iDSD BL.
    2. iDSD - 4/5 | iDSD BL - 5/5
  • Macklemore & Ryan Lewis - Downtown (feat. Nally)
    1. I love this song due to the quirky nature, and more importantly a mixture of a lot of instruments and styles. The iDSD BL sent a massively (good) deep bass into my head thanks to the xBass boost (Although with the bass can get too messy with the U10). It is a toss between the 2 as the iDSD has more detail and sounds more forward. But in the end I had to give it to the iDSD BL for making me enjoy the song tremendously.
    2. iDSD - 4/5 | iDSD BL - 5/5

Final thoughts between the iDSD and iDSD Black Label.
I would call this unit a more matured iDSD with minor refinements that makes it great. I rated the Black Label 44/50 (compared to 42/50 for the iDSD). With my gear, the Black Label is darker overall with a slightly higher low end, and very ever so slightly recessed treble. Although I reckon that they may have added a touch too much boost to the XBass+. It would be nice if it came with a 2 step selector like on the iCan. Compared to the iDSD, the iDSD is a little more airy and detailed, but somewhat sterile and boring. The 3D+ setting is better implemented but I do not use them most of the time. Toggling it on certain songs (unplguged/live) can certainly complement the song, but use it wisely. All that said, if you are looking for an all-in-one solution, you cannot go wrong with both. The iDSD BL would be more polite to most songs, and also able to satisfy your inner bass-head, but could be too much for cans like the Beyerdynamic DT770, Fostex TH900 and Shure SE846.
 
Things that I would like to see on future revisions
2-step Bass toggle (found in the iCan), USB to Lightning cable for instant connection for iDevices.

Great review and comparisons. I've got the iDSD micro and the BL on the way. Looking forward to A/B-ing them. Do you mind briefly commenting on how the BL performs against the Mojo?

I felt the Mojo is a very good performer for its size. Price talk will be subjective, but for me yes it is reasonable. Solid aluminium body and very very nice pebble-like material for buttons. The Mojo has a lively sound. Bass is tight and punchy, vocals crisp and highs are nicely placed. If i remember correctly, the Mojo outperforms the iDSD (non BL) very slightly by having a more organic tone. the iDSD sounded more sterile and digital. Having said that i reckon the BL is as good and better value (due to the different connectivity and control options) than the Mojo. If you would like an all-in-1 portable dac, no doubt the Mojo will win due to its size and capability. However if you would like a desktop setup, my money is with the iDSD BL.

Thank you for the reply, good information to have for future reference. The iDSD BL will join my desktop setup so size is no worry. Saying that, I do take my iDSD micro for portable use too...Thank you again for the review and reply.

100+ Head-Fier
Pros: Desktop class sound, DAC/amp very versatile for a wide range of iem/hp pairings, neutral and resolving yet engaging sound signature that pairs easily
Cons: Only (trans)portable, not quite convenient to use with DAPs, 3D switch a bit too close to volume knob may cause accidents
For the purposes of this review I will refer to the iDSD Micro Black Label as the BL
Thanks and appreciation goes out to iFi Audio for organizing this tour – it is a privilege to be given this opportunity to review the BL. This unit will be returned after 1 week to be passed on to the next reviewer in the tour.
 
 20161219_111832_HDR.jpg
 
Preamble:
This is my second official review on Head-Fi, so I would gladly welcome any suggestions for improvement, or tips on what I could include so that it would be more helpful for other Head-Fi’ers in evaluating gear for purchase. I thought a bit about how to structure this review because I generally find it challenging to review DACs as compared to headphones or earphones. This is because it is not as easy to generalize a DAC’s characteristics and sonic qualities as compared to a headphone (or earphone), and they might sound slightly different with various pairings. I think that the most useful way to pin down a DAC’s sonic performance is to compare how it performs with different headphones and also comparing it with other DACs.
 
I value timbre and tonality, then resolution and soundstaging (depth and realism over plain width). My listening preferences tend toward neutral but slightly dark, and I appreciate good low-end extension, texture and slam. I’m a vocal lover so the midrange is very important to me – mids need to have clarity but retain a level of musicality so that it is engaging and not sound congested or too analytical/hollow. I’m highly sensitive to treble, and harsh/uneven/forward treble can fatigue me easily. However, I appreciate high quality treble e.g. tonal correctness vis-à-vis real instruments as I know them (cymbal/violin tones) without any glare or peaks. High quality gear tends to tick most of these boxes easily.
 
Packaging and Accessories:
The BL comes in a standard white box, and includes –
1)   felt pouch for the BL
2)   female USB A to female USB B cable
3)   3.5mm to 3.5mm adaptor
4)   rubber pad (presumably for putting under the BL on a tabletop)
5)   USB A male to USB B male adaptor
6)   Two black rubber bands (for stacking the BL)
7)   3.5mm to 6.35mm jack
8)   Standard manual that explains the jacks and switches that can be found on the BL
 
Design and Build:
The BL is solidly built, and beautifully finished. I personally love the metallic black finish, and aesthetically I prefer it to its predecessor in silver. It is a compact design, and at times I still wonder how iFi has packed all that functionality into its chassis. I wouldn’t exactly call it portable but it is definitely transportable, especially if you are one who usually carries a small bag around e.g. a messenger or backpack (like I do). The volume knob allows you to do very fine adjustments, which can be very useful, and is quite smooth but retains enough traction for accuracy and to avoid accidental volume changes. The only gripe I have about the layout here is that when toggling the 3D switch I have the tendency of accidentally pushing the volume knob as well, because of my fat thumbs. People who have leaner digits or greater finger dexterity should have no worries though.
 
The XBass and 3D switches feel sturdy and have a nice tactile feel when flipped. There are switches at the bottom of the BL, one for toggling between using it as DAC/Amp and as DAC only, and IEMatch, for toggling in use with highly sensitive earphones. There are 3 other switches at the side of the BL, one for power mode, one for polarity and the last for sound filters. I find that the 3.5mm input jack and the 6.35mm output jack is well placed for portable use, because that means that you can stack and still place the BL in an upright position in your back with those jacks facing up, allowing for fairly convenient volume manipulation on-the-go.

Sound:
Well here comes the most important part. I am running Audirvana+ on a 2011 Macbook Air 13”. Settings on the BL are usually on ‘Normal’ mode with IEMatch off unless specified.
 
The first setup sees the Sony A15 as DAC, with line out into the BL, paired with the Aurisonics Rockets. The second setup uses the Onkyo DP-X1 as transport, feeding the BL with USB into the HD650. Then, comparisons 1 and 2 pit the BL against the Concero HD, which is a widely praised DAC and my desktop driver, albeit with less functionality than the BL but priced higher ($549 for the BL and $850 for the Concero HD), through the HE400S and the HD650. In the comparisons I usually kept the bass and 3D switches off in order to give a fairer comparison, and added comments about their selective use.
 
Comparison 3 tries to pin down the performance of the BL in driving custom monitors (BA drivers), in contrast to my usual DAP, the Onkyo DP-X1.
 
 
Sony A15 (Line Out) > BL > Aurisonics Rockets (and HD650)

20161219_164506_HDR.jpg
 
I remembered that I had the line out jack for the A15, and added this setup because I considered that this is actually a transportable option. Besides, iFi does provide 2 black bands for those who might want to stack the BL with their DAPs. It may not be convenient for many but the sound quality may change your mind. This is desktop quality sound, available on-the-go.
 
I volume-matched the A15 with and without the BL as accurately as I could, and I loved what I heard. Even with the XBass and 3D switches off, the audible difference is already significant. Comparing ‘Don’t Know Why’ by Norah Jones with and without the BL, there are immediate gains in air, space, and imaging, with greater vocal presence and resolution. Norah Jones’ voice is more focused; instrument placement increase in definition and clarity, and soundstage also gains some width and air.
 
With the XBass toggled on, the midbass is pleasantly elevated to give a little more slam, decay and texture. By texture I mean that the bass can be ‘felt’ more – a little bit more tactile. The caveat is that not everyone might like this difference, because it may be a little too much north of neutral for some. Without also toggling the 3D switch on, the presentation turns a little dark.
 
I loved the presentation with both the XBass and 3D switches turned on. The 3D switch re-balances the tonality of only the XBass switch by giving the music a treble lift. But that is an understatement. In this setup the 3D switch seems to provide a more ‘open’ sounding presentation. Vocals become a bit more forward and engaging without losing transparency. The soundstage increases in height, fills up the imaginary area somewhere above your forehead, along with a tad more width. The presentation also gains a lot more air and instruments have more breathing room and are nicely separated. The treble moves from the sonic background to a place where it suddenly has a little more sparkle and clarity.
 
The result? Greater immersion into the music with excellent resolution, transparency, and musicality. Switching back to the A15 alone causes the music to sound compressed and somewhat claustrophobic. Given that the A15 has a small footprint, I would actually seriously consider this portable stack as a serious rig that gives you desktop class performance that you can actually carry around in a messenger bag.
 
(I tried this stack with the HD650 just for kicks, of course with power mode on “Normal” and IEMatch “Off”. Turning the XBass on put the thump into the low end of the HD650s, however, it might not always be tasteful depending on track and preference. In many cases it changes the HD650s bass from being heard to being felt, working well as a result. I also toggle the 3D effect on simultaneously, and for most tracks, again, most noticeably makes the stage taller and more immersive, and adds air in the vocals and slightly more instrument definition. Imaging improves, together with a greater sense of realism. Even on a track with heavy cymbal work, tonality is never compromised, and with the HD650 the presentation still maintains its coherence and cohesiveness. However, as I note later (heads up), I suspect that more treble oriented cans might not synergize tonally as well with this pairing. I am really enjoying how a (trans)portable stack can drive HD650s properly.)
 
 
Onkyo DP-X1 > BL > HD650
 
The HD650s are the stuff of legend, and are well known for their audio quality. In fact, Massdrop recently ran a drop in collaboration with Sennheiser for the HD6XX, which basically replicates the sound signature of the HD650s. The HD650s are known to be slightly dark with a musical and lush midrange presentation, with the ability to scale up with better sources and amps.
 
As tracks are playing I experimented with the BL’s power settings. I found that the “Turbo” drove the HD650s better than in “Normal” mode, but with the drawback of not having much volume control headroom – in between being too soft with channel imbalance or too loud for any listening comfort. In comparison to “Normal”, I found “Turbo” to provide slightly better control in the bass, and midrange notes were very slightly thicker. However, I ended up doing most of the listening in “Normal” mode for the reasons stated above.
 
Compared to my memory of the non-Black Label iDSD Micro, generally the BL improves on its predecessor by providing a tighter grip on the bass, retaining midrange accuracy but having somewhat thicker notes lending itself to a more ‘musical’/engaging vocal presentation, for lack of a more appropriate term. Treble reproduction is remarkably accurate without giving in to any harshness or glare (perfect for someone like me), and maintains clarity without erring on the side of being clinical. Extension on both ends is very good, and detailing and resolution is top of its class in this price range.
 
The pairing with the HD650 is a fine combination, and makes for a pleasurable listening experience. Because the HD650 is slightly dark, it pairs well with the BL’s neutrality and clarity to provide immersion into the music. The BL’s 3D switch, again, gives tracks a slight treble lift (and more), and also required tuning down the volume knob a notch when applied. However, the net gains seem more track dependent than with the Rockets (on some tracks it worked wonders for soundstage and imaging, but on others recessed/thinned out the mids and did weird things to the imaging – became too diffuse), I would say that the 3D function/crossfeed is generally very well implemented, and worked well for most tracks that have decent mixing and mastering. I would imagine that with neutral or more treble oriented headphones or earphones this boost may not work as well, and might even in fact cause an overemphasis on treble reproduction.
 
 
Comparison 1:
BL > Lyr > HE400S
Concero HD > Lyr > HE400S
 
My HE400S is grill modded and Focus A pad swapped, which helps improve its inherent staging qualities and bass extension. The comparison is done with the switches on the BL off, and set to “Preamplifier” mode. To be honest, when I first swapped out the Concero for the BL on the HE400S, I was a little shocked at its performance –the tonality was quite similar, and technically it is pretty close. In fact it was so close I was hard pressed to tell the difference at first listen, and it was only after critical listening that I managed to sieve out some small differences. This speaks volumes of what iFi has managed to achieve with the BL, when you get a DAC that competes easily with higher priced DACs in the sub $1k category.
 
The Concero HD gets the edge for macrodynamics – bass slams a little harder and the presentation is slightly more energetic. The Concero HD low-end extension also reaches just a step lower than the BL. However, the BL’s bass is hardly far behind, albeit comparatively quicker and faintly lighter.
Midrange/vocal resolution and clarity is top notch on both DACs, and I cannot pick them apart. For vocal-centric music both DACs present a highly immersive performance, drawing you into the music. Cymbal work comparatively sounds very slightly tizzier/hotter on the BL, but I’m really nit picking here, and so the Concero gets the nod for a slightly more natural treble timbre. The Concero HD also seems to extend a hair more than the BL but my ears are not as good with treble extension so take this last comment with a pinch of salt.
Staging is a touch wider on the Concero, but seems a touch deeper on the BL. Imaging and separation brings both DACs neck to neck.
I suspect that this result has also got to do with the pairing of the headphone’s sonic qualities, and in this case, the pairing of the Concero HD and the HE400S is more synergistic for my preferences. I conclude that this is a very impressive showing by the BL as DAC.
 
 
Comparison 2:
BL > Lyr > HD650
Concero HD > Lyr > HD650
 
Results are mostly similar to the HE400S, however, an interesting point of deviation worth noting is that I prefer the treble tonally on the BL with the HD650 over the Concero HD. This leads me to conclude that it has to do with DAC/headphone pairing when it comes to tonality. It also squares with what I have learnt in my personal audio journey, that synergy between your gear is the most important thing – getting the most expensive gear is not as important, because upstream gear may not play nice tonally with your current gear.
 
 
Comparison 3:
Onkyo DP-X1 > Legend Omega (Balanced)
Onkyo DP-X1 (line out) > BL > Legend Omega
 
Well, what can I say – naturally as a compact desktop level DAC/Amp offering the BL in SE trounces the Onkyo in balanced, even though the Onkyo does put up very decent competition, and performance is close.
 
Power mode is on “Eco” and IEMatch is at “Ultra Sensitivity” – that leaves ample room for the volume pot, even though comfortable listening levels for me hover at around the 9 to 11 o’clock markings on the knob.
 
With Norah Jones through the BL, her voice is slightly more focused with a bit more resolution and clarity. Imaging also gains a little more precision and definition, with some added air in the presentation. Because the Legend Omega is slightly dark in presentation, using the XBass on added too much bloom and decay to the bass for my liking. However, the 3D switch provided pleasing results. The treble gains precision and detail, and with the lift in treble the presentation also gains some air. Again, soundstage most noticeably gains height and a sense of “openness” (similarly, height and a smidgen more width). Notes are a little cleaner and more defined. However, the only thing I noticed is that the mids, although with some improved resolution, seemed to have taken a small step back in presence and is relatively less engaging than just with the Onkyo’s balanced out. On further listening I suspect my mind may be playing tricks on me as it adjusts to a larger stage presented through CIEMs. Somehow in my audio experiences midrange quality and soundstage spaciousness seem inversely proportional most of the time (i.e. the thicker and realistic the midrange, the smaller the stage; the thinner and hollower the midrange, the larger the stage). Of course this is a generalized observation based on the select gear that I’ve had the opportunity to listen to.
 
With only the 3D switch on now, on Coldplay’s “Birds” track, through the BL, bass reaches down low, and has great attack and impact. If I can summarise the sound, two words I would use are ‘control’ and ‘precision’. I hear a lot of detail in individual instrumental and vocal spaces. The increased soundstage height from the 3D switch really helps with the spatial presentation and definition. Bass is well defined and fairly tight without being too analytical. Midrange is clear without losing much musicality, and the treble sits harmoniously with the rest of the spectrum without sacrificing any detail or sparkle. Tonality is pretty spot-on here, and with the detail retrieval and spatial qualities it’s one heck of a listening experience.
 
The 3D switch is really beneficial on most classical tracks because of the increased presence of the HF spectrum and the improvements in air and staging. Most of the time it helps immerse one in the music and allows you to zoom in on any single instrument and passage. The balanced out on the Onkyo alone presents treble in a softer manner, and instruments are not so defined. If I may invoke a visual analogy, its akin to switch from 4k (BL) to 1080p (balanced out). This difference may prove starker (read: more audibly discernible) when applied to classical music than genres like pop, because of the number of instruments at play. I would also add that the BL has better microdynamics e.g. small volume changes in different sections are slightly more audible than just using the balanced out. The BL also hits slightly harder, so in terms of macrodynamics it also has the slight edge. The BL’s ability to render clarity and retrieve detail without losing musicality really allows the listener a fine experience over the Onkyo’s balanced out alone. Here the BL is definitely the better performer, especially so for classical music lovers.
 
Conclusion:
 
The iDSD Micro BL is truly a formidable device with a fantastic DAC and a ton of functionality, suited to the most sensitive of in ear monitors to the most inefficient and demanding of headphones. Its strengths lie in its neutral yet cohesive and very musical tonality, presentation of space and ability to resolve fine detail. Together with the capability of toggling the presentation with the XBass and 3D switches it is incredibly versatile, presenting the listener with a range of options for pairing with different headphones/earphones with varied sound signatures. I personally really dig the 3D switch, and I feel that it is very well implemented. It works wonders with darker sounding headphones with improvements in air and soundstaging (and sounds superb with the HD650). I suspect its effect varies primarily because it is track dependent (and headphone dependent).
 
For audiophiles who do not mind the inconvenience of stacking, I would highly recommend the iDSD Micro BL as a (trans)portable option, paired with a DAP like the Sony A15 it will yield wonderful sonic results. As a DAC/Amp desktop solution for someone looking to enter the world of hi-fi I cannot more heartily recommend it. At $550 I think it has tremendous price to performance value (albeit a little steep if one is only starting out, but worth it), its DAC section easily competing with more expensive DACs in under the $1k range. Its functionality and small footprint is an added bonus. Bravo, iFi Audio, for a most excellent product!

Headphoneus Supremus
Pros: Incredibly clear sound, multitude of sound options, build quality, TURBO power! Good value.
Cons: TRANSportability, 3D not the best on some genre/songs, switches can too easily move
Oh my gawd this amp is incredible. If this is what moving upscale is, then I am in. I am beyond smitten. I am thrown face-first-headlong over the cliff. Enjoying the massive jet plane drop like never before. Traveling at warp 57, my Tennmak Pro’s have NEVER sounded this good…I await the crash to the ground. This would be a godsend, as it would be the final ecstasy to my full body experience.  I cannot breathe, yanked from my body it is as I hurtle towards that ultimate death…. Which would be welcomed as it would free me from this overwhelming envelopment of sound. A veritable cacophony of senses….Can we have more than five?! You are damn right we can…hitting the 3-D on Coldplays White Shadows, I give myself up. I give in to the sensory overload, which it provides. An out-and-out pummeling of sensory trance. I cannot bring myself to move past this. I don’t WANT to move past this. I want to curl up in that fetal position holding the Black Label close as I approach the end. Willingly, I protect the iDSD, so that it will survive and I won’t. It MUST survive, so that others can experience what I am. It’s as if I am David Bowie’s Lazarus….he willingly gave in to the cancer in the end, knowing he had produced such a masterpiece, giving to us, so that we may enjoy. Fighting like heck to the end, he rebelliously threw Black Star at us, so we would remember how damn good he was. A magical genius who told cancer what it could do…going out on HIS terms, to the dreaded disease…so that we would survive. This is what I must do so others may experience this primitive core explosion. This is a sense of not dread, but Paradise. Absolute Paradise. I give myself up so that you may survive.
 
 

 
More background:
 
Watching the Australian Open tennis tournament the year they used Coldplay’s Paradise as the go-to song, I watched some tennis. Some extraordinary tennis. Australia was facing record heat during the tourney. The players didn’t care. They competed, some to the full 3 or five sets, as the gender determined. There were some matches that went well beyond the normal 6-4 fifth set. The crowning jewels were the semi-finals and the finals, culminated by the Men’s final, which paired Rafael Nadal & Novak Djokovic (https://en.wikipedia.org/wiki/2012_Australian_Open_%E2%80%93_Men%27s_Singles) in the longest match of the Australian Open history…in the heat…It was beyond spellbinding. I’ll admit I’m not the biggest tennis fan (my better half the wife unit is though, so I watched) but this whole tourney has me. Like the Black Label. The two mega-stars threw guts and sweat and heart and determination and every other superlative I can think of in my feeble mind at each other. Neither would break. There were breaks where the two would cross paths going to their respective benches, and they would low five each other. They knew what the match meant to the other and they would not yield. Eventually after 5 hours and 53 minutes (ALMOST SIX HOURS!), Nadal yielded. It was an instant classic (a term thrown around in this social media drooling-drivel-day), and some regard it as at minimum a top ten contestant for best final ever…A match which culminated in the dignitaries speaking for FAR too long…to the point that one of the Open Marshalls sought out two chairs and bottles of water for the champions (both in my mind) and he received more applause than any of the speakers…that’s how tired the two were. They could barely move…You might ask, what this has to do with the ifi…and you would be correct to shout that comment at me.

THIS was a tennis match!
 
I fully believe after a short 45 minutes of listening that this device was crafted from the grit, the sweat, the blood, the Australian clay which those two idols of tennis competed on and gave up to that day. Shorn from the ground Nadal & Djokovic strode, the iDSD micro BL is a masterpiece. Simply smacks in the face to its competitors like Bowie to cancer. A full forehand volley driven of 125mph at its opponent head. A volley of such force that you must react or be laid out. Luckily for all of us, I do react and stop just short of the bottom. I thankfully come to my wits and stop; landing gently thanks to the parachute offered by the ifi iDSD micro Black Label. I cannot wait for more impressions.
 
I haven’t even brought out the big guns yet…
 
I am extremely grateful to the folks at ifi for the inclusion of me on the world tour. I have never done a tour such as this, but drawing from my experience on another recent tour, I will do my best to convey my likes, dislikes, quirks and joys. This review will be as open as I can. The tour unit will then be sent to the next lucky victim. My hope is that I can get the parachute packed for them…

Initial Impressions:
 
I have no experience with units of this magnitude, let alone price. My closest ownership is the Schiit Magni2, which I also use regularly. A comparison not really meant (or is it?), but one I will do (I didn’t). There is much difference, besides price.
 
From my unboxing, I was rather startled as to just what to expect when I first saw the BL. I was very happy whenst the lid opened. A very black rectagonal cigar-shaped box greeted me. This unit is not small. It is meant for not only desktop use, but also TRANSportability. This would be the piece with which all of your other portable gear sits upon. An excellent foundation with which to start. Through all of the knobs, toggles, connectors, and switches; a small green light illuminates to show that “Yes, I am working, now begone and listen fore I smash your head.”
 
From those multitudes of connecting options, I floundered for a good ten minutes trying to decipher where to hook my iPhone 6+…a simple start, and I completely bottled it. Eventually I was able to determine (stupid, I am) that the simple 3.5mm to 3.5mm right angle cable, which I raved about in the unboxing was the tool of choice. Until know, I did not let on what a dolt I was…
 
DSC_0034.jpgDSC_0035.jpg
 
 
 
 
Daunting though the size might be, the controls are logically laid out, and easy of function. Industrially-efficient is what I would describe. All switches, toggles, plug-ins, and cord/cable outlets are pretty much where they should be. No real surprise, and the red labels on the black aluminum body allows for fairly quick identification when needed of the three-way switches on the side. And those three-way switches are of light action. So be careful, especially when moving from the “normal” to the “turbo” setting on the amp. Yikes! As one becomes familiar with the switches, the red labels would simply be the back up. My one qualm is the toggles. I was worried in my opening about the “fragility” of them; how they might handle their location. I will say that due to the connections of the headphones in the ¼” jack and the 3.5mm input jack the two are protected. My worries seem unfounded at this point. What is bothersome from the toggles is quickly reaching them, as needed. I can see one wanting to toggle off and on the X-bass or the 3D between songs. This is where there can be a bother. But since they are toggles, a light flick either way takes care of that. No harm done.

Red lettering makes for a somewhat easier read
 
 
At a retail price of $549, this is not cheap for entry-level people. This is a definite step up. And it should be. With the reputation behind ifi’s other successful products such as the first generation micro iDSD as well as the micro and Pro iCan’s, it only makes sense to make an “improved” mid-fi with which to anchor the line up. Reading up on the old micro iDSD reviews it was very well received, called everything from “The Overachiever” by @ClieOS to a “True Swiss Army Knife” by @peter123, and the “New Wave of British Invasion” says @twister6 was in full swing.  With a reputation for tailoring amps to quite specific IEM’s or headphones, my hope is that this is more Swiss Army Knife as opposed to specialist. Initial impressions bely this thought.
 
With a size slightly longer than a 6+ (YES, it IS!), stacking could be accomplished. I’m not sure how portable or practical that would be, but it can be done! It would dominate smaller DAP’s such as my Fiio x3ii, but such is life. As stated, many will simply use the BL with their desktops or laptops, so the size will not hinder.

Some have said that with the new black color, they could not see the function terminology such as “turbo” and “DSD,” on the back. That just doesn’t bother me. This isn’t about what the unit says, it is about the sound. And my initial impressions were darn good if’n you couldn’t figure that out…
 
Included with the BL is a Crown Royal-like suede pouch in which you would carry the unit and the necessary cables for the day. Functional, and no frills it does the job, albeit a tad small and snug. An assortment of cables and connectors is included in the box, such is the variety of ways one can connect the unit. Boasting such technological advances as:
 
• DAC digital signal and digital power sections upgraded
• AMR Global Master Timing® femto-precision clock system upgraded for ‘super low’ phase-noise/jitter
• Analogue signal and power sections revised
• 3D+® performance-tuned / XBass+® performance-tuned
• Latest Output stabilisation network offers less distortion
 
The BL comes quite well equipped…as it should.

All of which mean the unit should be better. From initial third-party experiences, I can say the results are positive. I have no personal expertise with the old. With the addition of the “Headamp” Turbo setting, one can enhance the bass settings another notch beyond the normal. If that is not enough, then the XBass adds that final “11” to the mix. Think Spinal Tap, with the power to back it up.

Once my initial WOW settled down, I thoroughly listened to see if the above-mentioned settings were simply an “enhancement” of the sound. My old ears did their best…

Detail:
 
DAY ONE:
My listening was broken up into an odd assorted way, to some maybe. I spent a thorough day solely with the Tennmak Pro’s on my iPhone 6+ and the BL. What a joyous, pleasurable day it was! If my opening description wasn’t enough, then I will simply add that the BL brought out the best of the Pro’s. Solid, full, warm sound emanated from the Pro like I had never heard. Rich mids, solid but slightly boomy bass (sometimes) and a treble of sufficient quality came through so that temporarily I forgot that this was a $21 IEM playing through a $550 amp.
 
This would be a case where the better source definitely enhances the lower priced item. Sometimes faults come through when using a “cleaner” power source, as if the deficiencies are laid bare-naked in the snow. Not a pleasant option or vision (please don’t ask…), but in this case the Pro doesn’t MIND being put bare, in fact it enjoys the frolic and gladly rewards with that warm sound I mentioned. Kind of like dancing through the snow with a nice mug of hot cocoa, laced with Bailey’s for good taste. Darn, that sounds really good right now…
 
DAY TWO:
I followed that day with a single day using the Nova in the same set up. OK, this makes more sense…an IEM in the same category as the amp. What a wonderful combo this is! Open more “airy” and brighter than simply through the iPhone. Detail oriented I heard things, which were hard to come by using my other amps. With some of my other setups, I would “hear” the sound, but it was sometimes fleeting, such as when I worked as a Biologist studying birds… If a new bird came along on my survey, I would separate out the new sounds from the ones I had already identified. It was not that I didn’t hear the finer tones in my normal set; but with the BL, it wasn’t as if this was a new sound.  There was no mistake…that tone, which might have been the fleeting sound of a far off bird on my surveys was DEFINITELY there. The birds/sound presenting themselves to me in a nice orderly fashion. No hiding, but not boisterousness either. Just a neat progression of sound. Harken back to a full procession coming in front of you…or the birds presenting me with easy identification without needling or disorder. Just presented for my listening indulgence. Enhanced bass with the switch on paid dividends to the Nova, adding that little extra I craved from them before. Now, I am in no way dissatisfied with the Nova, but the bass switch added the right amount for my taste. EQing would get me near the same thing, but toggling the bass on is a simple way to enhance for my taste.
 
With the 3D toggle switched on, there is a definite jump in mids and a slight treble bump. In conversation with a fellow Head-fier, we discussed whether this was a placebo effect from the gain of mid/treble tones or if it was real. I do not have the equipment to gauge the truth (others are as we speak), if one can define the truth that way. My seat of the pants explanation (and reading about the crossover system involved) is that there is a shift fore and aft in my cranial matter in regards to the soundstage. Switching back and forth, or playing a song fully then repeat I can “sense” added depth in the anterior/posterior relationship of my cranial mush. Call it a bodybuilding “loudness” switch.  Some have stated that the effect on the micro/micro BL is not as effective as other units, but it works quite well for me. I could sense a larger soundstage, but not enough to make the instrumentation feel separated by a distance. I left the switch toggled on for the whole time; except times I wanted an “unencumbered” sound with which to listen.
 
I find it quite marvelous that technologies such as the XBass and 3D can fit into a unit this size. My-oh-my how sound times have changed!
 
Some have stated they wished for a bigger boost in the XBass toggle. I would disagree. I think there is enough of a bump at 6dB to satisfy most. I like the push added to the overall sound. A quick jolt of bass for those IEM’s which might be bass-shy. If I want more, then I will EQ my source.
 
DAY THREE:
Switching to my Fostex T40RP Mk3’s, I pushed the BL to the Turbo setting. I still had to push the volume pot to about halfway for a good listening level for me. And it was quite the stunning combination. Going through my iPhone 6+ with a newly acquired Lightning camera kit attachment, I was able to use the Digital SPDIF port, bypassing the DAC of the 6+, and fully using the BL. Holy buckets, what a difference! And yes, one would expect that going from a Smartphone to a dedicated DAC/DAP; but still the revelation was astounding. Rich of sound, full of body, slightly warmer than when run with my other setups, the Fostex have not sounded this good. I would call them a slightly “dry” sounding can OOTB, but one with which I like very much. EQing can take care of my personal tastes with the T40, but using the BL, there was no need. With 3D and XBass toggled on, I sat back and fully felt Dire Straits Down to the Waterline. Knopfler’s guitar rifts are a masterpiece to be enjoyed using good equipment, and I had found my listening of choice, whether it be from my x3ii or 6+, it was purely a marvel. Clean, clear, crisp, with the full sound one would expect from an amp of this caliber. It did not disappoint. And a volume, which satisfied me to the fullest. I cannot imagine pushing the pot higher, for fear of hearing damage.
 
DAY FOUR-SEVEN:
Running all set ups through my MacBook Pro, 6+ and x3ii; I tried all set ups, but fell back to the listings below. If I didn’t like the set up, I quit using it within about 15 min. My time was too short to audition something which was not that pleasant.

Stacking with the Fiio x3ii
 
 
 
 
Summary of Sound Prefs (no particular order):
 
iPhone 6+-->Lightning Camera kit-->ifi BL-->Tennmak Pro:
 
Just a thoroughly satisfying sound. A Marvel of todays technological advances from a cheap IEM to a moderately priced mid-fi amp; this was my favorite go-to sound for day to day. This would be my set if I had only one, which would travel.  twenty one pilots Hometown was my first listen, and my main song no matter what I test. I follow this up with Coldplay’s White Shadow or A Sky Full of Stars. The three songs hit a full gamut of sounds, which I can use to gain that initial sound, which I liked so much. That initial push of “what can this unit do.” From the keyboard, which nears distortion to the very forward sound of the Coldplay songs, this is a good judge. There is no hiding; and the “grouping” did not disappoint. 
 
iPhone 6+-->Lightning Camera kit-->ifi BL-->Campfire Nova:
 
My favorite setup for the majority of the music I auditioned. Bowie’s Lazarus is haunting enough under normal listening; but with this grouping, I could VERY easily imagine myself holed up hugging the wall in his hospital “suite.” Trying darn hard not to be noticed, lest I get thrown in the Institution myself, I would listen to his beautiful voice; and it would sound identical to this match, getting drawn in with his dilemma, his final push before death calls his name. This set brings me closer to his music than I have with anything else. And I am grateful. A nice slightly warm sound, which does not intrude, not wanting to draw attention to itself much the way if I were hunkering in Bowie’s hospital room. Sipping single malt, this would be my unwind unit in the evening.
 
iPhone 6+-->3.5mm to 3.5mm cable-->ifi BL-->Tennmak Pro:
 
This was the set with which I wrote my opening. As you can tell, it was sufficiently “adequate” that I was able to eagerly anticipate the “better quality” hook ups with gleeful, slack-jawed-joy. I was in listening bliss. I was so taken aback by that initial listen, that I wrote the opening on the spot. Such an honor it was, that I replayed Coldplay, twentyonepilots, David Bowie, and Lyle Lovett for three straight hours. Such was the joy, that I lost track of time and it was 0200 the following morn before I realized. Not that I cared, not one iota because of the delight I had experienced. Easy setup and with the length of the 3.5mm cord, easy to transport. This was the closest set up to actually SHOUT at me. Grab me by my shoulders, screaming WAKE THE HECK UP AND LISTEN!!!
 
iPhone 6+-->3.5mm to 3.5mm-->ifi BL-->CA Nova:
 
I spent the whole of the second day running this way. And I was not disappointed. I ran the same songs, over and over, with the same results. A more full sound, rounded out by the fore/aft added depth of the 3D, the Novas ran well. While not as good as the SPDIF/Lightning setup, a thoroughly enjoyable sound encased me, to the point where my co-worker was essentially right next to me before I heard or SAW her. A trance worthy of an Ouija board I was in…My second audition of the BL was a complete success, and it was during this day that @nmatheis convinced me to purchase the Lightning camera kit and I would not be dissatisfied (which I wasn’t!). Just more “Wow” moments all around…
 
Fiio x3ii-->3.5mm to 3.5mm-->ifi BL-->Tennmak Pro
 
Since the Fiio is a definite step up from the iPhone, I spent the next two days thoroughly auditioning my music with the x3ii as the source. This was probably the least used system, but not because it was the “worst.” I simply wanted to spend more time with the Nova inserted here. That said, I loved how the x3ii brought a cleaner sound to the table than Amazon Music, or Tuneshell (which has since failed me and I have deleted the app for reasons I will not state here). Yes, of course it was of higher quality music than the other, but I wanted to make sure I tested the arrangement in my best possible light. My best units if you will. While the quality was better, I did not enjoy this system as much as through my 6+. I know, I know, that doesn’t make much sense, but I felt the music I had was a bit flat. Even running through the “Line Out” from the Fiio it just wasn’t full enough for me. The warm Tennmak’s and XBass could not make me happy with my recordings the same way the 6+ did. I’m not sure I can explain it any better than I just wasn’t happy with this. Would it work? You bet, it wouldn’t be my first or second choice, though.
 
Fiio x3ii-->3.5mm to 3.5mm-->ifi BL-->CA Nova:
 
If I absolutely had to choose one set up, this would be it. The Novas warmer sound could compensate for the colder-more analytic sound of the Fiio. I think I stated in my review video, how with this set the two (BL & Nova) could overcome the cold nature of the x3ii, and it did. This set up would (and did) need the most EQing to be completely satisfactory of listening pleasure. I guess I have come full circle then; I used to EQ, and then swung HARD the other way. Now I am back to EQing. At least with this grouping I am. And that’s ok in my book. I hate to keep using the same bloody commentary regarding “slightly warm and full,” but…since I already stated that this would be my one go to set up, I really do not think I need to describe it any better. Using the line out on the x3ii, I was quite OK with letting the BL dictate and run the sound program. It was kind of like having a simple DJ with me who could only do three things well (XBass, 3D, Eco/Normal/Turbo) and that was quite all right. More than adequate, this was a DJ I could afford.
 
Fiio x3ii-->3.5mm to 3.5mm-->ifi BL-->Fostex T40RP Mk3
 
What a superb way to bring out the best in these hard to drive cans. Turbo was more than suitable to drive these “near-mid-fi” closed cans. I opted for the T40 because I wanted the better of the bass units, and the closed back, for privacy. These do not disappoint, but the amps I have, short of the Schiit Magni2 & Fiio A3 (almost) cannot really do them the justice which I heard through the BL. I have talked about a “veil being lifted” in previous reviews, but I think that would be an insult to the Fostex. Call it having the necessary “passing power” to cruise by the slower vehicles in the mountains. While the Schiit is sufficient, it doesn’t compete with the BL. Kind of like a BMW 3-series with four passengers and full luggage… The A3 would be the equivalent of a Prius…It would get me there, and in quite fine manner; just not like having a Ferrari F455 with which to do the job, and in not so near a hurry. There was no worry for power using the BL. I barely went over ½ on the volume with the BL/Fostex. Anything more, and I was ricking hearing loss in my mind. I really don’t want to lose more…

Conclusion remarks:
 
So there you pretty much have it. My time was far too short for my listening WANTS. I found myself craving just one more day knowing it wouldn’t happen. I think that is the highest compliment I can pay to this delightful unit. If a unit (especially a loaned/tour unit) can have my mind begging for just one more day, by the SECOND DAY; then I am enamored. I am taken. I am engaged to the listening for the short time available to me. Liken this to a long distance relationship where you will meet for a week, knowing that each day draws closer to the separation. The leaving, which will tug, no yank at you over the increasing distance which WILL happen. You keep thinking, “I really should be focused on the moment, lest it is lost.” But you obsess over the time ticking down, ever closer to the farewell. But during that time, you force yourself to envelop the moment, devour that time together, devoting full attention to your time together. Even though that damn clock is ticking ever louder in the back of your mind; you scream silently to it, "SHUT THE F-UP! I’M NOT DONE HERE,” as you surrender yourself, your time and your ears to the listening; knowing you must. Otherwise the task is lost. And not only do I not want that, I desperately do not. It would be a disservice to your relationship, your short but oh-so-sweet time together.
 
You really must give in to the relationship to fully understand what is going on, otherwise the time is wasted, as is the relationship. Hopefully I have not wasted that time on this wonderful relationship, courting a future together, which I would willingly, GLADLY give in to again. And again. Lover's In Japan, from Coldplay's excellent Prospekt's March album is a very fitting end to this review. The timing could not be better...
 
Is it perfect? Heck no. Does it have a few quirks? Yes, size to me is the main drawback. It is almost too big to be commonly portable, but workable. I would definitely keep this in a desktop situation, though if  “forced” to; it is too good not to use… And the 3D is not for everyone. It can artificially inflate the sound stage fore/aft as well as the mids becoming overly bright. It sounded good on some tracks, not good on others. So a simple toggle of the switch changes that. But the positives FAR outweigh the negatives. Three amp settings with which to choose from, as well as the XBass switch and the excellent sound from the digital out highlight those positives. Fine-tuning of IEM’s through the sensitivity settings is another quick way to tailor the listening. A nice touch.
 
I really want to thank Lawance and Jared for this relationship. This time together with the WELL more than fine ifi iDSD Micro Black Label was all I could ask, albeit too short for my lusting listening pleasures... It really is a fine unit, which I would gladly spend more time with, and my hard earned dollars upon. That is about the highest praise I can give. Go listen, it will be worth it.
