    Pros - Excellent sound, Feature rich, high performance to price ratio
    Cons - Non-existent volume indicator, awkward shape (ifi micro product series in general) - Long and thin
    About Me

    I stumbled into the head-fi world when my itchy fingers picked up a Shure SE846 back in January’14. Since then, it has been a long journey, and I’m only just starting. Exploring the various IEMs and portable set-ups available, I’ve slowly learnt to appreciate good sounding gears at various price points, culminating in my decision to start writing reviews in order to contribute in my tiny way back to this community. I’m still looking to slowly develop a more consistent writing style as well. I’ll appreciate any feedback anyone has on any areas I could improve on!


    I have varying music taste, so I can listen to/ appreciate most genres of music too, from classicals to pop/rock and almost anything in between, and choose my listening genre at a particular time based on mood, although I’m still building up my music collection.


    Personally, I like my bass. It doesn’t have to be in huge, overwhelming quantities, but it has to be good, clean and deep base. I don’t like recessed mids, while I’m generally tolerant towards treble, and can appreciate both bright and rolled- off trebles.


    As with all reviews, this review is purely subjective, based on my own experience, gear and preference, so YMMV!



    The iFi iDSD Black Label here was kindly loaned to me for the purpose of this review, as part of their global tour. The unit I am currently reviewing is part of the Asia group. I will not be posting too many pictures of the iDSD BL as there have been many of much better quality that I can hope for in the reviews posted by other reviewers in the tour group.


    About the iDSD BL


    iFi is based in the UK, and they have an extensive line-up of products that are rather reasonably priced.


    The original iDSD was an exceptionally good transportable/portable DAC/AMP, and the latest version of the Micro iDSD improves a lot on it. As with the previous version, iFi has managed to pack a huge amount of power in a portable package with excellent battery, an extremely capable DAC that plays every format worth delving into and some. That and the fact that the original iDSD was developed with the community is yet another bonus.


    The iFi iDSD Black Label here is the latest iteration of the tried and tested iFi iDSD, and is priced slightly higher vs the original iDSD at $749 SGD in Stereo Electronics. It’s an incremental upgrade of the original iDSD, especially for the volume knob, which loses the original’s tendency to have imbalance at lower volumes.


    Ok, as with my most recent few review, I’ll start off with the most important aspect of any review...the sound!!!!





    Headphones Used

    Audio Technica ATH-R70x

    Sennheiser HD800

    64 Audio A12 CIEM


    Tracks Used
    Some of the tracks used for this review are:

    Storms Are On The Ocean

    Amber Rubarth

    Spanish Harlem

    Rebecca Pidgeon



    Drum Impro

    Dali CD

    Ignorance (Acoustic)


    Just A Fool (ft. Blake Shelton)

    Christina Aguilera

    Cheek to Cheek

    Lady Gaga / Tony Bennett



    See You Again (ft. Charlie Puth)

    Wiz Khalifa


    The iDSD BL has a signature that is pretty neutral with not much coloration except for a touch of warmth compared to the original, and seems to pair pretty well with headphones that have leans towards being bright (eg. HD800). It’s transparent with a drier (more analytical) signature, but is definitely more musical than the original. Imaging is excellent, with a wide, open soundstage coupled with good depth. This allows for its ability to pull out details to shine through. Dynamics too is excellent, never once feeling “flat” or smoothed out. It certainly isn’t laid back or smoothed over.


    On that note, for a portable device the BL powers the HD800 without struggling and still has enough juice left to spare.


    With the HD800, I used the Turbo mode with IEMatch turned off. Normal mode works well with the HD800 as well. Bass extends deep and vocals seem to hit a really sweet spot. The highs are extended without any sibilance. This results in an overall musical signature that draws me towards the much vaunted HD800. This is certainly one of my favourite portable devices when paired with the HD800. Whenever I feel that the bass is lacking (which isn’t often!), I’ll just flick the xBass switch, and ta-da, satisfaction!


    With my A12, I had to switch on IEMatch and change the power mode to Eco. With this settings I can safely set the volume knob to around 12 position, giving me room on both sides (+/-). Despite this, I can safely turn it to normal mode and keep the volume knob low to about the 9 position with no issues, which couldn’t be done with the older model. The BL does seem to sharpen the mids and treble of my A12, which I’d rate as being on the more laid-back side. This seems to result in giving the A12 more air up top, improving on its already commendable soundstage width, but more so on its sense of “height”.


    Compared to the original iDSD, there is some added warmth that makes for a more musical tilt of the original iDSD signature, which I liked but found to be somewhat dry and analytical. Treble on the BL is sparkling and a tad bright, but sounds natural and is certainly not piercing nor grating. This result in a device which pairs better with brighter sounding headphones, such as HD800, TH900, it is much better in taming the brighter/harsher treble of these headphones as compared to the original iDSD.

    Finish/Build Quality


    As described in the product name, this version of the iDSD is clad in matte black aluminium with orange lettering. Simply put, it’s extremely cool (black is my favourite color!). Its form factor does not differ one iota from the whole micro series, thus retaining what I personally feel is a more transportable form factor than a portable form factor.


    The switches are well labelled, as are all the connectivity options, including the USB port, and the various inputs and outputs. The volume knob is another area with an improvement over that in the older version, with less/no channel imbalance at lower volumes. Volume control is smooth and yet firm.


    My only gripes with the BL are the indicators. There isn’t one on the volume knob, which would have been a welcome addition, to make it easier for us to know the current volume. Not a deal breaker in my opinion though.


    Also, as with the original iDSD, the labels for the filters, polarity, power and IEMatch are placed on the bottom of the device. Unless you’ve pretty much remembered them, you’d be forced to pick up the device to change/check your settings, which may/may not be often depending on your usage.

    Packaging and Accessories
    iFi pulled out all the stops here, and leaves nothing to be desired. The iDSD BL includes the following accessories:

    1.     USB 3.0A female to USB3.0A male cable (1M)
    2.     USB 2.0A female to USB 2.0B female cable
    3.     USB 2.0A female to USB 2.0B female short adaptor
    4.     iFi’s standard purple RCA cables
    5.     Rubber bands
    6.     6.3mm to 3.5mm convertor
    7.     3.5mm to 3.5mm cable
    8.     Mini Toslink to Toslink adaptor
    9.     4 silicone feet
    10.     Silicone sheet
    o    Velvet Carrying Pouch



    1. The iDSD BL, as with the iDSD, comes with a myriad of features. I’ve listed them, as shown in iFi’s website on the BL:
    2. ·     The heart of the original iDSD, the dual-core Burr-Brown, is retained in the BL. It’s one of the last chipsets from Burr-Brown Japan (though it was introduced post-merger), and their ‘swansong’, and embodies all their converter technology and is unrivalled in terms of subjective.
    3. ·     Capable of true native playback of all music formats from MP3 all the way up to 512DSD/768PCM/2xDXD.
    4. ·     The latest iterations of 3D+ and XBass+ are appreciated technologies that further enhance the enjoyment of music. With a larger soundstage and deeper, tighter bass respectively, both are even more engaging and satisfying than ever.
    5. ·     iFi/AMR ‘OV’ series stands for ‘Operationsverstärker’ (German for Operational Amplifier). The ‘OV’ range IC’s use HCOFC copper lead-frames and 4N Gold bond-wire which are streets ahead of mainstream commercial chips that use inexpensive aluminum bond-wire, low-grade/low-cost copper in the lead-frames.
    6. ·     Os-Cons, originally from Sanyo (now taken over by Panasonic), have been around for a good while. Among the larger value capacitors useful in power supplies, they hold a special place. They have been used in AMR components up to the revered CD-77 Reference Class CD Processor.
    7. ·     Three power output modes, Eco, Normal and Turbo. If used in conjunction with the built-in iEMatch, the micro iDSD BL is able to have the power and gain dialed-in to perfectly suit all headphones from the super-sensitive Sennheiser IE-800 up to the hyper-hungry HiFiMan HE-6.
    8. ·     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.
    9. ·     From the very hungry HiFi Man HE-6 down to the Sennheiser IE-800, the micro iDSD Black Label is able to play hi-res out and about for 6 to 12 hours respectively. Even when not in use, it is able to charge an iPhone from 0% to 100% two times through its side USB charging port.

    IMO the original iDSD was one of the best portable DAC/Amp in its price range, punching way above its weight. The myriad of options only served to improve its value. Now that Chord has launched the Mojo, which is an excellent DAC/Amp, it is good to see that iFi has responded in kind with the BL. It is certainly something to listen out for, and is IMHO one of the best DAC/amp at its price point without even a shadow of a doubt!

    *I had to re-write it without the benefit of most of my notes which were inside, this review has been shortened to less than what I expected. Hope I didn’t miss out anything important. Lesson learnt L

      @Tobias89 Did adjusting the IEMatch settings do anything to change the sound of the A12 significantly? Hearing that the sound might be thicker or warmer than the Mojo kind of scares me. The mojo was already unlistenable on my ciems.

      @DigitalCitizen I had another listen to the BL at Stereo just now, and I take back what I said. I find it be slightly "thinner" and drier compared to the Mojo. That's on my A12. Sorry for the confusion :x
      Personally I didn't find the Mojo to be thick/lush, but to be pretty "neutral" and balanced, being not too lush yet not too clinical. The iDSD retains some of its predecessor's dry/clinical signature, but adds that touch of musicality.
      I didn't notice any major changes in the sound of my A12 regardless of the IEMatch settings.

    BLACK Background can pay my full attention on my music
    Written by monster2046
    Published Mar 14, 2017
    Pros - Good Sound, Affortable Price
    Cons - connectivity is not fit to eastern music lovers
    This is my pleasure that I will be the tester of ifi new product, idsd black lablel (let us be short as BL).
    As a newbie of headfi, I am whole heartly to try difference devices.  
    When I first read about the spec of the BL, I talk to myself that "woo......."  From technical perspective, the components are good and I reach to exited mode that I want to test the BL.
    The appearance is just as as the previous version, just changing the colour from silver to black. To me, I don't care on the appearance while I just focus on the sound is match with my preference or not.
    The device can support optical, usb  but unfortunately, my on hand dap (Paw Gold and DX 90) haven't optical out, the coxial in of BL can't match with DX90 coxial out.  The usb connection, is difference with mojo and vantam.  I just can test the amplifier function.  (iDSD primary design is for desktop connection)
    I think there are many reviews of Paw Gold and I don't explain anymore.  I just talk about my personal feel of Paw Gold line out to BL.  I listen my sound with using a pair of CIEM, Oriolus 2 only.  I set the power to normal.  
    My comment is very simple, just same as the colour of the device, BLACK.  I can't hear any noise from the BL.  The background is too dark and I just can pay my full attention to listen my music with no any interference.  
    The power is enough and driven my earphone give me a sense of "enrich, solid".  Even less than medium volume can drive my earphone.  To my sense of hearing, the vocal (especially female singer) is charming and attractive.  This is easily for me to imagine a lady ,standing on a stage, is singing a song for me.      
    When the Bass enhance button is on, the bass will be increase 3db (I guess).  As Oriolus 2 is a 4-driver hybrid earphone, this can give me a sense of warm surrounding me.
    However, 3D function is really bad to me.  Once open the function, I just feel that all sounds stick together and spoil all music that I am listening.

    This is a review for the micro iDSD Black Label edition, not the original micro iDSD

    I firstly want to thank Lawrance at iFi for letting me use the micro iDSD Black Label for a few months. I had originally requested the micro iDSD, but the timing of the request was right in line with the launch of the Black Label edition.

    This was a brand new unit, so I let it burn in for quite some time in case I receive any scrutiny about that. : p

    Most people don't know this, but the orange paint on the micro iDSD Black Label fluoresces under UV light. It makes for a cool photography subject, hahaha.




    I made an unboxing video to explain what goodies are included with the iDSD BL box, as well as a basic overview of the unit. Like most, if not all, iFi products, you will be equipped with all of the items you would ever need for the product inside of the box.

    Design: 4/5
    One of the things that sets the micro iDSD Black Label apart from other DAC/amps is its design. Using the same chassis as the other micro line of products, the iDSD BL carries its unique shape and form factor. This is, however, why I docked a point from the Design score. Although the iDSD BL is portable, there is no way it would fit comfortably in a pocket. This is more of a transportable DAC/amp than a portable one, and that limits its functionality. On the other hand, since transportable DAC/amps are smaller than desktop-sized ones, it does have the benefit of being able to fit on a cramped desk more easily.

    If you want to use the micro iDSD BL as a truly portable DAC/amp, there is a battery inside of it that lasts 6-12 hours depending on usage. I almost exclusively used it as a USB-powered DAC/amp with my laptop though since that's how I would use it.

    With the idea of portability in mind, the use of a male USB A connector makes sense since you can just use a Lightning - female USB A adaptor, or an OTG cable for Android-based devices. However, since I consider this more of a transportable unit than a portable one, having the use of a male connector is an inconvenience if you want to use your own USB cables, or audiophile ones at that. iFi's own Mercury nor Gemini cables are compatible with the micro iDSD BL without the use of an adaptor.

    Outside of these issues, I think the design of the micro iDSD BL is pretty solid. From the outside, the whole chassis is utilized in terms of inputs/outputs/switches. The Black Label edition goes for a stealthy black-orange appearance and I like that very much. On the bottom of the unit, there is some print in a glossy black paint such that it's very discrete, yet available if you need to refer to it. One small complaint I have is the lack of a clear indicator of where the volume knob is at: there's only a very small, uncolored, dimple near the edge of the front part of the knob.

    The whole concept of the micro iDSD BL being the "Swiss Army knife of audio" is really exciting to see. It has so many inputs and outputs, gain and power output settings, and audio tweaks in general that it should satisfy anyone who likes to modify their systems' sound. The only set of options you won't see in this device are balanced inputs/outputs, but given the size of the chassis and the sheer amount of stuff crammed into the device, it is quite understandable. The combo S/PDIF/coaxial input/output port should be quite useful to many.

    Moving to the inside, the Black Label edition adds some improvements to the circuit that should be appreciated. Having femto-second global master timing clocks is not a trivial thing to be added in a sub-$1000 device, let alone sub $600. That to me is just mind-blowing. Upgraded components both in the digital and analog sections of the device are also welcome, in addition to the XBass+ and 3D+ additions, which I think are well-done. The XBass+ and 3D+ features are separate analog effects done on the headphone output, so it's not just a DSP effect.

    The design choice to use a hybrid R-2R/ΔΣ Burr Brown DAC chip is fascinating! Basically this DAC chip takes the 6 most significant bits of your PCM source file and does a digital-to-analog conversion process through a R-2R resistor ladder, true multi-bit, process. The remaining bits go through a typical Delta Sigma modulated pathway.

    The DAC chip also decodes DSD natively in a true 1-bit fashion that only involves a single low-pass filter.

    On top of all of this, the DAC is capable of playing back DSD512 (Octa-speed DSD) and 24/768 PCM. Not that there's any music in this format, but a 24/768-capable DAC is able to transfer DSD256 via the DSD over PCM protocol without any problems for Mac OS users.

    The use of 3 different filters for your music also allows the user to tune the device to their own liking and to experiment with the concept of filters. In my review video, I had mentioned that the filters seemed to be more like digital filters. This is only half-right. The filter switch acts as a digital filter selection during PCM playback. For DXD playback (which is actually still PCM), a fixed analog filter is used. Likewise for DSD playback, a selectable analog filter is used. This is a very unique set of features for filters that I have not seen in any other device in any other price range. Kudos to iFi for including this as a design feature!

    Furthermore, the inclusion of not one, but two gain systems allows the micro iDSD BL to have an incredible amount of versatility for use with headphones. Eco, Normal, and Turbo gain modes are kind of your standard low/medium/high gains respectively. However, the micro iDSD BL has an additional 2-stage gain stage meant to be used for sensitive headphones and in-ear monitors specifically: IEMatch. I think this design is simply brilliant, and more devices should have something like this, seriously.

    Quality: 4/5

    Since this category is really arbitrary, I will use this section to rate the micro iDSD's overall build quality and feel.

    The only reason why I docked a point from this category is that the switches don't feel very robust minus the metal flip switches for the XBass+ and 3D+ settings. The rest of the switches are rather cheap-feeling since they're just plastic and they don't have a lot of resistance. I didn't add the silicone feet to this unit since I am not the owner of it, so I mostly just placed the micro iDSD BL on the silicone mat instead.

    I don't mind having buttons or switches on the bottom of a unit as long as they don't accidentally get activated. Unfortunately most of the switches on the micro iDSD BL tend to get moved easily, and this adds to the problem of having this unit in a pocket for portable use.

    For everything else around the device, things seem to be of top-notch quality. The chassis feels diamond-solid [better than rock-solid] and super robust, the paint seems to be of high quality and I don't see it chipping off in the long-run, the inputs/outputs feel solid and not flimsy or loose, and the volume knob is silky smooth to use (actually it's pretty addicting to turn since it feels smooth but it has a very, very, very nice sense of resistance; seriously, try it out!).

    Audio Quality: 4.5/5

    I'll start by mentioning the amplifier section. I am personally not a huge advocate for amp matching with headphones. If it gets loud enough, that's usually good enough for me since I listen to music at fairly low volume levels.

    With this in mind, I think the amplifier section of the micro iDSD BL is great. It can drive my Etymotic ER4SR and OPPO PM-3 with ease, specifically in Eco/Ultra-Sensitivity settings. Again, if it gets loud enough, it's good enough for me; there is absolutely no reason for me to use higher gain settings for these headphones. The background is dead silent without any traces of hiss at all. Only when I turn off the IEMatch and turn the volume all the way up on Normal gain do I start to hear background hiss. However, at this point, you wouldn't be using such sensitive headphones from the get-go.

    I did get the chance to hear the micro iDSD BL with a Sennheiser HD800. I just used Normal gain mode and it drove them just fine like a typical solid state amplifier without any issues. I'm still not a huge fan of the HD800 myself, but at least the micro iDSD BL can do a comprable job at driving it.

    I have no idea when anyone would ever use the Turbo gain mode on the micro iDSD BL. Perhaps to be able to drive the infamous HiFiMAN HE-6, or maybe even the AKG K1000? I didn't get the chance to use the micro iDSD BL with such insensitive headphones unfortunately. Those headphones aren't easy to come by in the first place, but it's, again, good to know that the micro iDSD BL has a gain mode for them: 4 watts of power into a 16-ohm load is not a trivial thing to do in a battery-powered audiophile-targeted device.

    XBass+ and 3D+
    Briefly mentioning the XBass+ and 3D+ switches, I actually really liked them. Unlike some devices, the micro iDSD BL uses discrete circuit pathways for these two settings, which are also all analogue and not digital (AKA not DSP).

    The XBass+ might not be for everyone since it's a pretty substantial boost, but I liked it because it was in the lower-/mid-bass area and it didn't affect the upper-bass/lower-midrange a whole lot. This is my preferred way to do a bass boost since it stays more true to being a bass boost.

    The 3D+ switch is essentially a crossfeed effect, but again, it is all analog. I typically don't like using crossfeed since it sounds weird to me, but the micro iDSD BL seems to do it more justice than not. I should give a warning that it does seem to make recordings brighter-sounding, so if you have a bright music, it might be too much. That being said, enabling the 3D+ switch sounds like it angles the music 30˚ inward from the horizontal, kind of like speakers pointed at your head. Neato!

    Now on to the DAC portion of the micro iDSD BL. I think this is where the sound aspect gets interesting. I spent most of my time listening to the micro iDSD BL as a DAC with the STAX SRS-2170 system.

    I firstly want to make it clear that most of my listening sessions were done with the Standard digital filter. These filters could arguably affect how people perceive the sound. Between the three digital filters, the Standard one sounded the best to me. Here's a summary of how I felt between the filters, although I must stress that the differences are pretty subtle and not everyone may hear them:
    • Standard: The least harsh-sounding filter to my ears, with a larger sense of space, but at the cost of a limited ability to image
    • Minimum-Phase: Harsher-sounding to me compared to the Standard filter, and has a reduced soundstage, but better imaging (having more space between instruments)
    • Bit-Perfect: I really couldn't hear a difference between this filter and the other ones

    Playing PCM files in this manner, I noticed that the micro iDSD BL kind of has a "Goldilocks" sound compared to other DACs I'm used to hearing. The ESS-based DACS typically have a bright and more detailed sound ("SABRE SOUNDTM"). On the other end, AKM-based DACs tend to sound really warm. Perhaps it's due to iFi's use of the hybrid Burr Brown chip, but I find the micro iDSD BL to sound a bit warm as a whole while having a somewhat detailed sound: it's a blend of both the AKM and ESS DAC chips' sound.

    Perhaps it's due to the Global Master Timing of the micro iDSD BL's femto clocks, as I've found to be the case for other femto clock-carrying DACs, but I really marveled how well the micro iDSD BL can image. It didn't have the largest-sounding soundstage that I've heard in a DAC, but being able to determine where an instrument is within the soundstage and how clear that instrument is from another is more important for how I listen to music.

    Playing DSD, I really like how the micro iDSD BL sounds. Smooth is the best way to describe it. Again, the Burr Brown chip that the micro iDSD BL uses has a true DSD playback loop in that a 1-bit digital-to-analog conversion is done with a single low-pass filter. The filter switch in the case of DSD only changed the volume to my ears, so there's not really much to say about those.

    I liked the sound of the micro iDSD BL's DSD playback so much that I used software to upsample my music to DSD256 throughout most of my listening tests. One of the original reasons why I wanted to hear the micro iDSD in the first place was because I was interested in iFi's "Octa Speed" capability. In OS X, you can only play DSD music through the DSD over PCM (DoP) protocol in which the DSD source is disguised as a PCM file so the computer can transfer it to the DAC to be decoded as DSD (note that this is NOT a conversion process). Therefore, playing back DSD256 music...
    DSD256 data rate = 2 channels * 1 bit * 44.1 kHz * 256 = 22.5792 Mbps

    Equivalent PCM data rate = 2 channels * 16 bits * 44.1 kHz * 16 = 22.5792 Mbps (AKA 16-bit/705.6 kHz)
    requires a DAC capable of reading a 16-bit/705.6 kHz signal. Obviously the micro iDSD BL can accept a 32-bit/768 kHz signal, so this is probably one of the only DACs that can play back DSD256 music on OS X! Unfortunately in Windows 10, I couldn't get the DSD512 stream to work properly as it kept stuttering for me.

    Upsampling even CD-quality files seemed to make them sound smoother to my ears. Daft Punk's "Derezzed" song is one of my favorite test tracks to use for bass and brightness. When I talked to the iFi folks at CanJam at RMAF last year, they mentioned that they liked "Derezzed" too, but it can be pretty harsh-sounding at times, in which I agree and that's why I use it as a test track. I asked them about their "Octa-Speed" feature since there's probably like 5 music tracks in the world that are recorded in DSD512 and they mentioned that upsampling "Derezzed" to higher DSD rates actually helped reduce its harsh sound. This is exactly what I heard when upsampling any music track to DSD256: things just become less harsh overall and the sound seems to become smoother and more pleasing to the ears because of this.

    One theory I have for this phenomenon is due to the nature of DSD decoding. All of the songs' original frequency content is still retained, but higher rate DSD sampling rates have higher signal to noise ratios. This in combination with the Burr Brown's true DSD pathway might benefit the digital-to-analog conversion process.

    Value: 5/5

    If you couldn't tell by this review, I really, really, really like the micro iDSD BL, and especially for the price. Considering all of the features this device has, combined with all of the included accessories, and its overall sonic performance, I think this device could be double the price and I would still recommend it. Seriously, this is one beast of a device.

    Outside of the largish/portablish design, the kind of annoying male USB A connector, and the somewhat flimsy-feeling plastic switches, I'd whole heartily give the micro iDSD BL two thumbs up. I still can't believe iFi is only setting this at a $549 USD MSRP. That's just mind-boggling.

    Thank you for taking the time to read/peruse through this review! : )

      Thank you! I tried to change the buffer settings a bit, but I couldn't find one that worked out for my computer.

      Thank you for the kind words!
      You firstly need the appropriate media player. Audirvana+ or JRiver Media Center support the upsampling feature. In A+, open the preferences, go to the Audio Filters tab, click on the DSD button and set the option to DSD256. In JRMC, go to the options, Audio tab, Settings section, DSP & output format, check the Output Format tab, click on the Output Format tab, and select 4xDSD in DoP format from the drop down menu under Output Encoding.

      I tried Audirvana+ for a while, but I was not happy with its library import and management features. I am in fact about to give JRiver a try, so I will definitely follow your advice and see how it pans out.
      Thank you!

    Super versatile, great functionality, great SQ

    Pros - Wide range of format supported, multiple I/O to choose from, a power bank i guess?
    Cons - Black on black lettering on the back, $ (as always)


    Special thanks to iFi Audio and local distributor for setting u[ this review tour of iFi Audio micro iDSD. First off we will be going into the looks of the BL, and then into SQ from RCA out and then the HO, and finally the software side of them.


    I'll just shove a couple of pictures in your face and not write a lot.
    20170306_211427.jpg 20170306_211454.jpg 20170306_211508.jpg 20170306_211521.jpg 20170306_211536.jpg 20170306_211553.jpg
    As the pictures show, there is quite a lot of I/o to go with and on the 5th picture is actually a USB power output  aka charger to external devices.


    20170301_214846.jpg 20170306_211641.jpg
    My setup will be using the iFi BL sourcing from PC - iFi iUSB, and on the second picture you can see a supplied OTG female to a printer connector female cable, which is a totally weird way to use them, but then USB OTG cable becomes a useful tool to use, readily available. The speaker used is Alesis Elevate 5.
    Secondary setup is similar but on the headphone jack with HD650.

    Alesis Elevate 5

    On the RCA out to the speaker, the BL can serve as a pre-out, which enables the usage of X-Bass + and the 3D+. On music these both are hell of a weird thing to use as on the 3D ON, it makes the music sound so thin but wide, studio albums get totally out of shape by using this. So, i switched to the cleaner direct output, which disables amplification on the BL and it sounds so much better. 
    Bass power isn't exactly the strongest, but it gets the job done cleanly. On Metallica's newest album "Hardwired", it gives the thump and pace up so the whole momentum is in tempo.The bass drum stumps are clearly heard and bass guitars doing the magic . I am digging this setup on metal genre, totally not bad at all.
    Mid vocals are very clear but not overly forward. Pronunciations can be heard and spelled out clearly. James Hetfield doesn't have the best of English, and that I can hear lol. 
    Treble is clear and crispy, not overpowering the other portions of the music, and just stays together with the percussion. Different cymbals type can be differentiated clearly.
    Soundstage I couldnt comment much, maybe due to the properties of my speakers. What I heard is not very wide soundstage, and so I couldn't tell whether it is the limit of the BL or my speakers.


    In order to use the headphone out, I had to mute the RCA while having it connected, since both can output AT THE SAME TIME!! Tha'ts one weird feature, or maybe a flaw? I don't have a clue.
    On the HD650 connected, the Trebles are set even clearer maybe because of the closer proximity of the drivers to my ears, but the quality of it still maintains, with every different cymbal notes differentiable.
    Bass thump on the HD650 is much stronger, and gets even more with the X-Bass on. Bass goes on full force but with so much control on it that I can set this up with the X-Bass on as a "compensation / correction" for some songs with weaker bass. Definitely worth considering enabling this on certain situations only, as not everything needs so much bass on it.
    Vocals are slightly weaker on the headphone out, and guitars + drums can slightly drown out the main vocalist, but there are some other factors which are to be considered. The metal genre might have a characteristics of such, where emphasis is more on the guitars and vocals are secondary only.
    For soundstage test, I enabled the 3D+ and tested Nightwish. All I can say is 3D+ is not suitable for music at all. Placements of instruments get disrupted and becomes unbalanced. With the 3D+ off, it has better balance and becomes less artificial. One scene I tried which I find totally digging the 3D+ is movies!! I used Jungle Book to try the 3D+ and boy I enjoyed the movie that I get emotional and goosebumps all over. I think 3D+ has found it's place in my books, movies~ oh yeah~~


    As like other iDSD, installation of their special driver is neccesary, and in Foobar2000, ASIO has to be selected, to avoid interruptions from Win Mixer. I haven't tried OTG mode, but it should work straight off the bat without much hitch.
    2017-03-06_21-48-58.jpg 2nd.jpg stream.jpg
    In the second image, under USB streaming mode, there are multiple selections, shown in 3rd picture. Asio buffer size is also selectable from 64 samples up to 8192 samples.

    Final thought

    On the appearance side, hoped they have changed the black on black text, and then the outlook will be just nice. Other that that, I have no problems or nags with this product at all. It can be used on battery power, charging devices too , and be sounding awesome while at it. What more can you demand for in format support? DSD, DXD and all common formats are there ready to be used. Really wished I could keep the unit but then it's a Lucid dream haha, oh well.

    iFi Micro iDSD BL: Once you go black, you never go back
    Written by proedros
    Published Mar 6, 2017
    Pros - Very Musical and resolving Sound , Versatility (can be used with both ciems and full phones), Great Bass/Treble Boost, Amazing Build Quality
    Cons - More transportable than portable, no availability for Balanced use/Balanced Cables, difficulty to see volume knob level may irritate some
    Before submitting my thoughts on the IDSD Micro Black Label (to be called BL from now on), I would like to thank the folks at Ifi Audio for organizing this EU Demo Tour and giving us the opportunity to listen to BL . Initiatives like that help both companies to expand their clientelle and customers to try something out before buying and i hope that these events happen more often, especially for such quality products like the BL.

    Ok , on with the review then. 

    First , some tech specs/stuff , which many reviewers before me have included in their amazing reviews, so i have decided to put as hidden text (click to read)

    iFi Audio Micro iDSD Black Label has:
    re-designed output stabilisation
    OV2627 op-amps upgraded analogue section
    Panasonic OSCON capacitors loaded power supply
    OV2028 op-amps loaded DAC power supply
    DAC voltage decoupling based on audio-grade ECPU film capacitors
    GMT® Femto precision clock system power supply upgraded
    iFi Audio Micro iDSD Black Label is:
    a tweaked to the roof original Micro iDSD
    a satin black version (with silk orange writings) of original Micro iDSD
    sonically much better version of original Micro iDSD
    loaded with latest 3D+® and XBass+® tech, superior over ones in original Micro iDSD
    10% higher price of $549 (ex-tax) / Euro599 (incl VAT)
    superior to original Micro iDSD
    Dual Burr-Brown DAC chips developed by Burr-Brown Japan before the TI acquisition, custom tweaked 
    to play all the way up to unicorn formats: OctaDSD (512DSD—there aren’t even any recordings that 
    I know of) to PCM768 (I don’t know if recordings exist for this standard)
    3 output modes: eco, normal and turbo and the iEMatch feature allowing headphones from 
    ultra-sensitive custom in-ear flagships to insensitive masses of metallic HiFiMan HE-6 glory
    Intelligent In/Out SPDIF Digital Optical/coax allows using the iDSD BL to feed your Sonos, or 
    plugging in your DAP when you feel the need to make up for it’s inadequacies
    Battery power for loads of time, with smart charging for your devices when you aren’t blasting 
    your aural cavities with wonders, delights, and delectable morsels of audio fayre (iFi advertise 
    6-12 hours battery playback, depending on how hungry your headphones are)
    iDSD BL comes with more in its box than any of the other’s I’ve opened. Here are the full contents:
    Micro iDSD BL
    1 metre USB 3.0A female to USB3.0A male cable
    USB 2.0A female to USB 2.0B female cable (for using whatever USB cable you like without straining the USB jack)
    USB 2.0A female to USB 2.0B female short adaptor (for using whatever USB cable you like)
    iFi’s standard purple RCA cables
    Heavy duty rubber bands for stacking your source on top of the iDSD BL
    6.3mm to 3.5mm convertor
    Short 3.5mm to 3.5mm cable
    Mini Toslink to Toslink adaptor
    4 iFi branded silicone feet (that’s a step up from my Micro iUSB3.0)
    A silicone sheet—is this for putting under or on top? I couldn’t tell, but it should provide some cushion
    A velvet bag for transport
    I will now discuss the most important parameter (to me , at least) - the sound signature/quality of BL. I am a guy who uses only CIEMs so all my thoughts are based on listening done with CIEMs.

    So, after fiddling around with the many options available , i settled down on the following for my listening sessions

    Source Setup Used : iBasso DX80 > stock 3.5mm to coaxial cable > iDSD BL
    CIEM Used :Hidition NT6 (6-BA CIEM)
    Power Mode Setting : ECO
    Filter Setting: Bit-Perfect
    IEMatch Setting: High/ OffECO POWER MODE
    Music Files Used : 16/44 FLAC (mostly 70s/80s disco/funk/soul and some 80s rock)

    So on to how this little bugger sounded. First things first : This is a great DAC/AMP. I really liked what i was hearing and could not turn this little ******** down once i started listening to it. In fact my loving ZX2 simply gathered dust while the BL was around in my house (and ears).
    The sound was very enjoyable to my ears. BL sounds full and musical , but without sacrificing clarity . It has an almost perfect balance of musicality and clarity.

    The bass hits very, very nicely without sounding bloated , i was really impressed by how good the lows sounded with my (relatively bass-light) NT6. Great job there iFi.

    The mids are lush and musical without sounding too sugar-coated, and they are very well positioned , neither too upfront nor distant. No complaints there again.

    The highs feel sparkly without reaching sibilance levels. When i wanted a tad more 'air' (on some 'veiled' recordings), the 3d switch took care of this perfectly  (I shall return to the 3D and Bass Boost switches later).
    Even though BL was only used in SE mode, i found it to have great separation and a big soundstage with very good placement, with very good width.

    Last but not least, some thoughts on the 2 available switches , the 3D and the Bass Boost.
    3d switch is a nice touch, as it feels like a booster for the high frequencies, while simultaneously creating asense of an airier, more open sound . It is nicely done and its effect did not sound 'fake' to my ears, and i found myself using it quite a lot, especially on recording which suffer from some clarity up top and sounded a bit 'veiled' to my ears.
    As for the bass boost i did not use it, as i found the bass very nicely done on the Bl and its quantity was more than enough for my needs , even with the bass boost switch turned off. When i tried it though, i found the bass increase tastefully done , so if you are a basshead , this switch should come in handy to you.
    As i said , i have been owning a SONY ZX2 for quite some time and i will present a small comparison with the BL, so that ZX2 owners get an idea how BL sounds.

    Compared to my SONY ZX2, i liked the DX80>IDSD BL setup much more. BL definitely feels like a step up in dynamics, sonic finesse and overall enjoyment.
    The mids sounded fuller , the bass had more power and the soundstage was bigger with better placement and separation. ZX2 is no slouch, but i couldn't help but think that ZX2 sounded at times almost anemic next to the BL sound.

    So is everything perfect on the BL ? Even though i was VERY pleased with what i heard, there are some things that could make this great DAC/AMP even better.
    First of all, I would have liked having the option of using it balanced as all my CIEM cables were TRRS terminated and i had to use a balanced>SE adaptor all the time.

    I can not imagine how much better BL would sound if I could go balanced, as it sounded amazing even on SE mode.

    Also , some people may have a hard time seeing where the volume meter stands, as there is not a dot or something to distinguish the volume level.

    Speaking of volume , I must say that I did not detect any channel imbalance at all , even at very low volume levels.

    But i am just nit-picking here , BL is an amazing device and I was quite amazed by it. In fact, if you are on the market for a DAC/AMP that shoots way above its price and screams 'QUALITY' , then BL should definitely be on your shortlist.

    iFi Micro iDSD BL: The Good Dark Side
    Written by BillsonChang007
    Published Feb 24, 2017
    Pros - sound quality, balanced, no channel imbalance, versatile with anything, power
    Cons - needs a more visible volume indicator, 3D+ can sound bright
    Why I love iFi and their products
    iFi have been known, reputably for their amazing amplifiers and DAC. Ranging from Nano to Micro to Retro and the most recent addition, the Pro line, iFi have an amplifier and DAC for different purposes and price ranges. The nano for on-the-go and affordability, Micro for transportability, Retro for the speakers and Pro for the extremes. Having tried their products, mostly the Micro line which they first set-off with, it never disappointed me in terms of sound quality. Throughout the years, listening to recommendations by users and reviews is what really brought them where they are now, being featured on the Head-Fi gift guide and not to mention other reputable audio review websites and it is not one, not two, but most of their products are outstanding.
    My favorite product that they have created so far is the Micro iDSD. It started back in 2014 where they started a thread in Head-Fi asking opinions on what this Micro iDSD really should be and from there, they take everyone’s opinions into consideration and kept the crowd updated throughout from hardware to software and the troubles that they ran into. When they introduced the Black Label edition of the Micro iDSD, I was all hyped and even more when they announced a tour for it! A huge thanks to iFi for adding me into the tour for this iFi Micro iDSD BL!
    I really appreciate how the iFi team gave the packaging a formality and it represents the company very well. What came with the original Micro iDSD is very similar with absence of a black carrying pouch which is no big deal but considering the Micro iDSD BL costs more at USD549 as opposed to USD499 for the original Micro iDSD puts be in doubt [both prices excludes taxes].  Other than that, it comes with instruction manual, 3.5mm to 3.5mm standard jack, 2x silicone bands, angled male type A to female type A USB, wired USB Female type A to female type B converter, left and Right RCA cable, 4x rubber feet, 3.5mm to 6.3mm jack converter, jumper, USB Female type A to female type B adapter and a piece of rectangular rubbery “thingy” that probably used for when stacking a phone on top to avoid frictions. With exception of the carrying pouch, the Micro iDSD BL comes with pretty much everything and there’s nothing short of. I have been using the original Micro iDSD for more than 2 years now and I never see the need to carry the pouch along anyway. If anything, it makes the ports less accessible when inside thought it was genius to have a hole cut for the USB.
    What's so cool about this BL
    The build and weight of both the editions are similar; all metal and weight is on the bulky side for such a small footprint but I think that’s how I would like it to be. Makes it sits properly on the table. As a proud Micro iDSD user for more than 2 years, I can safely say that, the unit is very durable considering I have not been nice to it partially because I am quite violent with gadgets. So no worries, go ahead, throw it in the backpack and rock but it probably won’t survive in the water thought. I have to say thought, thumbs up to the batman-like black finish with orange wordings that really stands out. However, good luck trying to read the unimportant feature lists at the bottom but really, it’s nothing important… or is it. Seriously thought, it is worded in black on a black casing. If anything, the original Micro iDSD’s volume knob is stiffer than the BL edition.
    Not only does it look like Bruce Wayne’s multibillion techs but it also features like his utility belt. It is a DAC and amplifier that also works as a preamplifier that can power from the smallest earphones to THE giant Bane. There are three power mode namely Eco, Normal and Turbo. Personally, I do not find the need for “Turbo” for any headphones just yet as at Turbo, it outputs 4, 000mW @ 16 Ohm of power and I doubt there are any headphones that needs it with exception of a few such as the popular HifiMan HE-6. In normal and eco modes it outputs 1, 900mW @ 16Ohm and 500mW @ 8Ohm respectively. For most headphones, Eco mode is more than enough in my opinion. However, what about earphones and headphones with high sensitivity? There’s the IEMatch. It has two switches; high sensitivity (-12dB) and ultra-sensitivity (-24dB) which makes volume more adjustable or you can have it switched off. Do note that, avoid using IEMatch on other modes; Normal and Turbo. “It is like pressing the accelerator while applying brakes” – iFi. Other features include XBass+, 3D+, polarity (-/+), and Filter (Standard/Phase Minimum/Bit-Perfect). Oh, it also features as a Plan B power bank at the side but keep in mind that, the unit takes quite a while to charge up.  There is also a small LED light on top which determine the status of the unit. It has a built in gen 1 iPurifier into it as well and up to Normal mode, it can purely drain on USB or charge at the same time in eco mode. Information on these features can be found here.
    The main course
    With all the Batman’s design and features aside, the sound quality itself is no joke either. I find it an amazing piece of amplifier and DAC combo. There’s perfectly no channel imbalance pass the 9’O Clock turn. While it is not as neutral as I expected it to be, it remains well balanced. The bass is tick tight and beats down to as deep as you could wish. Without the XBass, the bass is there but lacks the “bold”. The upper bass is what I like the most out of all as it has a good amount of weights and punches that anyone would appreciate. I personally find that the highs are a minute louder than the midranges and this result in a very fun and enjoyable sound. Throughout the listening experience, I find it entirely to be ultimately smooth, while attaining that speed on the punches at the same time, not missing any details. It just feels like you are driving on a Porsche at say 170kmph but you feel that the car is doing it effortlessly and that is how it feels like to listen to the Micro iDSD BL as a standalone.
    I think that the XBass+ and the 3D+ is what actually saved the amplifier side of it. Starting with the XBass+, it really adds very notable amount of bass to it and fits the “basshead” category just nicely and at the same time, with the speed, and thumbs that is just so good and pleasant to enjoy with. Without the 3D+, the soundstage is pretty wide but the separations feel a little bit packed together. Flick the 3D+, it is as if the musician just immediately spread out themselves from a small stage to an opera theatre and for movies, you could better aware of the environment of the scene. There’s one trade-off thought. With the 3D+, the treble can spike up and especially with female voices, I find it a ted annoying with the B&O H6 and Brainwavz HM5 but if the XBass+ is on together with it, it soothes the treble by adding "bolds" to the whole sound making the treble less noticeable although it is still there. Darker headphones like the Mr. Speaker’s Mad Dog have no big deals with this.
    I then connected the iDSD BL to Garage1217 Project Sunrise III w/ Amperex 6dj8 Orange edition and boy is there a huge improvement in comparison to the standalone without XBass+ nor 3D+. That said, the amplifier of the iDSD BL is great matched with the DAC but is rather average only. With the XBass+ thought, the iDSD BL have better bass in every spectrum than the tubes; speed, quantity, and depth. When both the XBass+ and 3D+’s running, the iDSD BL does stands pretty close to the tubes. The iDSD BL is definitely clearer but with the tubes thought, the soundstages, separations, and sound is just more “real” and so, so, so, slightly more airy. At high volumes [pass the 3’O clock], I find the iDSD BL losses its dynamic ranges and clarity, soundstages and separations gets a little mixed up. Not to worry thought, I doubt there’s a need to turn up the heat given there’s 3 different power mode.
    As a pure DAC itself, I find the Micro iDSD BL to be extremely flat and literally have no flavors. It is like an ice cream cone; it doesn’t have much taste but add the ice cream on top and you get a delicious dessert. The Micro iDSD BL matches well with any ice creams [amplifier] and it will sound amazing. It is airy and very analytical. Plugging in for the first time, really tells you how much details have you been missing all along. Not to mention its capability to hit up to DSD512.
    Now for the grand comparison. As Lex Luthor once said and I quote “God vs Man, Day vs Night”…
    The BL edition is better than the original in a few ways, but in many ways, they are quite similar. Besides the obvious color differences, exterior wise, they are pretty much the same chassis with similar ports and switches. The difference lies within; the BL uses latest and higher end components, the 3D and XBass gets a nice upgrade and indeed worthwhile. As a standalone DAC/amp, I would say that the BL is smoother, warmer, more refined and the two switches at the front is a major step up from the original and distinctly a better unit than the original. Channel imbalances issues are non-existence on the BL pass the 9’ O Clock. At the end thought, if you already own the original edition, you are better off spending the money elsewhere like a separate amplifier. I personally find that when using the two as a sole DAC, I find both to have similar sound although the BL are more “stable” with the channel imbalance. That said, the original edition at $499 or even cheaper sometimes, is still a very good DAC/amp while the BL is for if you do not own neither and its really worth the extra 10% difference. The original edition is also more neutral in comparison to the BL as a DAC/amp combo.
    Thank you for reading
    The Micro iDSD BL is yet another amazing unit, I wish I could spend more time to enjoy with. I was the lucky winner of the Micro iDSD 2 years ago and I couldn’t be happier to be able to listen to the BL. It is amazing and it still did not fail to wow me away. I especially enjoy it with my B&O H6; it adds necessary warm and bass to it with the XBass+ and I can leave the 3D+ off while still getting the airy and separation I wanted. It’s truly a match made in heaven. I have never enjoyed the B&O headphone as much before despite it being my on-the-go headphone. Overall, it is very versatile with anything you throws at.

      Nice. Agree with most of your points. The 3D is not a gimmick and it does add a feeling of space, but only sometimes. Depending on the source it can make the sound a bit too bright/grainy/fatiguing.

      The bass boost is well implemented tho. I almost never use it since the Z1R are already rich at that, but it's nice to have it.

      Did you notice the lag when starting play? And pops on power on/off?

      @beowulf thankss! Yea it did have pop sound on power but I think that is quite common on amplifiers [same to on-board soundcard on start up, phones, etc]. As for playback delay, it's also there but only at initial start-up and after maybe a min or two of not using it. I also find the lag slightly longer than the original.

      Folks, please do not forget to update the firmware of this device to the iFi_XMOS_V5.2B for it to have no delays whatsoever whilst using it as a pure desktop DAC/AMP
      It was driving me insane using windows 10 until I found out it auto sleeps every bloody second to save power.

    A great DAC-Amp full of features
    Written by rafaelpernil
    Published Feb 22, 2017
    Pros - Very smooth and natural sound, inmense versatility
    Cons - None
    To begin with, I would like to thank iFi for making this great tour and allowing some of us to test this product.
    I've been enjoying my original micro iDSD since January 2015 and it is really a piece to love. Its spacious natural sound, so efortless and delivering confindently in the serious Hi-Fi range... It scaled up as my setup did, unleashing deeper layers of detail by lowering it's USB noise (data and power wise) with a micro iUSB3.0, providing better dynamics and even better stereo presentation.
    To be honest, up to date, I am very happy with it. I tweaked my source (laptop) for lower latency thus outputing lower USB packet jitter, I adjusted the polarity of the components of my system for even better dynamics and so far everything pays for the efforts.
    Having said that, my system isn't complete yet, my speaker amp is kind of a bottleneck in here. I measured its noise and it doesn't even reach a S/N ratio of 70dB (Whereas iUSB3.0 offers an S/N ratio of almost 154dB). However, it can prove many points using it as a differential tool for both units, iDSD and iDSD BL.
    With no further adue, let's get into the review :D.
    For those of you who already know iFi, there's some key differences in this package over old products:
    -Rubber feet are smaller and have an iFi logo on it (Cool addition)
    -All accessories are now separed in two white mate carton boxes with satin iFi logo on it. I like it, cleaner and easier to pack.
    -The blue USB cable seems kind-of darker now. And slightly sturdier.
    And for those of you who happen to be first meeting iFi products, let me just say this: They give an Apple-like experience for the unboxing, simple and elegant.
    But for the fortune of us, they give a ton more of accessories, and to be honest, not bad at all. 

    *Fun fact: Their blue USB cable is the second best USB cable I have at home and I assure you it provides a nice smooth sound. Excellent considering it's built in!*
    Here I leave you some photos of the whole unboxing experience.
    WARNING: Staring too much at the unit will seduce your mind with its attractiveness
    Oh, here we are, look at that. Ain't that sexy? Sure this smokey black brother is catching your attention. (Yep, smokey as Johny Walker's Black Label, no coincidence)
    Labeled with orange and dark grey silk-screen print, it seems iFi is playing elegant once more, but better refined. No coincidence whatsoever, it reminds me to this Black Label whiskey. I see a clear evolution throughout their products, specially in the design department this time, no detail has passed unnoticed, carefully improved from the bottom to the top.

    Now, getting into the hardware, there are a lot of major changes, so let's recap:
    -Digital engine upgraded - Op-Amp OV2028
    -Analog section upgraded - Op-Amp OV2627
    -Zero Jitter/Femto clock system upgraded for lower phase-noise/jitter
    -3D+ and XBass+
    -Ultra-low impedance OS-CON polymer capacitors and Panasonic audio-grade ECPU film capacitors.
    I think it's going to be hard to discern where the improvements come from in each different scenario, but I'll do my best to find out what role plays each of these improvements in the final product. Let's call it reverse engineering :D
    I could give you some technical details from their webpage, but that would it give this review any value, would it? So, instead of that, I'll sign to iFi philosophy, and let the ears do the talking. 

    How does it perform solely as a DAC?
    First, comparing it to the original iDSD, I sat both units in Direct mode (Fixed Line-Out at 2V) and swapped my Oyaide neo d+ Class S USB cable connected to a micro iUSB3.0 after each test. The results proved this new unit instantly superior to the old one, giving far better texture, a better detailed bass, smoother sound and a better defined stereo image. However, I found soundstage better on the original iDSD, but maybe it is just a matter of time, to burn-in the new BL unit. I suspect improvements mainly come from improved capacitors, lower jitter and due to its improved analog section.
    By its own, without comparison, I would say it's one of the easiest DACs to listen I have tested. I listened to hours of music without noticing any disturbance in the sound. Which, by the way, happened to me sometimes with my original iDSD, sounding a little bit uncontrolled at highs.
    How dows it perform as a DAC-Amp?
    Well, I did some comparisons to original iDSD with the same source and the same blue cable and found out some interesting results. I used my micro iUSB3.0 as power supply and USB hub for both units:
    At first I equated the volume using a sonometer app and a 1kHz test tone and Black Label required more volume to reach same decibels. Which are great news, we have better gain control now!
     *NOTE: I haven't used the Oyaide cable because when swapping, I would have to turn off the DAC, turn it on again and readjust the volume to  get it powered via USB, where the micro iUSB3.0 helps with its 0.1uV noise floor*
    Taking into account the headphone amp, there's a major leap forward. A very significant difference, fixing a lack of bass texture and micro detail. I noticed a smoother sound, slightly better tone wise,
    with much better controlled highs, providing a solid image. It sounds more natural, with better texture and dynamics. Overall, very cohesive. But I would say original iDSD has a bigger soundstage.
    What about digital filtering?
    I perceived a lesser degree of improvement when comparing straight to USB port with iUSB3.0 as source. It seems this overhauled version has lower jitter and better filtering. A very good job!
    And now, talking about XBass+, there is also a very clear improvement. Bass boost is much more noticeable and fits quite nicely with many tracks. 3D Holographic + on the counterpart sounds slightly
    more unrealistic, a very nice addition nonetheless.
    Sincerely I would love to keep this unit with me. It sounds so great I don't wan't to stop music. It sounds so great I don't even have to worry about audio.
    Thanks for reading me, I hope you liked the review!

    Pros - Extremely versatile, impressive power output, lots of sound customization options
    Cons - First two seconds of every track are muted, slight channel imbalance at lower volume, bulkier and heavier than a portable unit should be
    I wanted to start this review off with a Swiss Army knife joke but it looks like several Head-Fiers have already did that so in a futile attempt to be both funny and original I’ll start off with a comic. ifiaudioname.jpg
                                                       I'm 99% sure this is how it went down
    I’d like to sincerely thank Hoomairah Atchia-Rawat from iFi Audio for choosing me for the Review Tour as well as Mateusz Przychodzień of Forza Audioworks for lending me his personal iDSD BL unit for evaluation. I was not paid to write this review and (unfortunately) I did not get to keep the unit. I did have a lot of fun writing this so there's that.
    Product description
    So what the iDSD BL actually is? Well, the iFi’s own website calls it “the world’s most powerful DSD/PCM/DXD Battery-powered DAC”. However I feel that calling the iDSD a DAC is doing it disservice as this device can do so much more than just convert ones and zeroes into an analogue waveform. So from now on I’m going to refer to the iDSD as a USTAB, a “Universal Soldier of The Audio Battlefield”. I believe this acronym reflects the nature of the iDSD BL much more accurately than “DAC/amp combo” or a “portable amp”.
    To explain in detail the thought process behind this name let’s talk about all functionalities of this little black box.
    Jean-Claude Van Damme with head-mounted iDSD BL, 1995
    1. DAC / Headphone Amp combo
    2. DAC only (with both USB and S/PDIF inputs)
    3. Headphone Amp only
    4. DAC / Preamp
    5. Preamp only
    6. USB to S/PDIF converter
    7. Powerbank
    1. Speaker Amp
    2. Coffee maker
    To underline the “Universal” part of the acronym even further, performance of the individual sections of the iDSD BL can be fine-tuned by the user.
    1. The DAC has three distinct digital filter and can reverse the polarity of the digital signal.
    2. The amp section has three levels of gain (nine if you multiply it by IEMatch settings), bass boost and iFi’s proprietary 3D Sound.
    3. The RCA outs on the back can output both fixed and variable volume.
    I’ll talk about all of these functionalities in more detail a little later on.
    Subtle, yet elegant design, with product shots on the top and side of the box with USTAB's specs on the bottom. Aesthetically pleasing, recyclable and stylish. I wouldn’t mind displaying it on a bookshelf like a Lego set for my guests to admire.
    More important than the box are its contents and here’s where iDSD BL’s USTAB nature shows up again. A lesser company would include just a USB cable and a 6.3mm adapter but not iFi.
    No, the British company wants their customers to be prepared for every type of audio combat scenario and that’s why in the iDSD BL box contains:
    iDSD BL unit
    USB 3.0 type A male to female cable (1m long)
    USB type B to type A female to female adapter
    Another USB type B to type A female adapter ( a shorter one)
    6.3mm to 3.5mm jack adapter
    Toslink to mini Toslink adapter
    RCA cable (0.5m long)
    3.5mm to 3.5mm interconnect
    Rubber covers for the RCA jacks
    Four stick-on rubber feet
    Two rubber bands for attaching the iDSD to a portable source
    Cloth pouch for storing the iDSD
    Silicone pad
    My only gripe with the USTAB’s arsenal is that it does not include a Micro-USB OTG or an Apple Camera Connection Kit despite being marketed as a smartphone-compatible device. But that is a very minor issue, overall I am really impressed by the amount of accessories included in the box.
    Oh iFi Audio, you didn't have to
    Additional 50 points to iFi audio for including this note in the box. It serves no practical purpose aside from making the iDSD owners feel loved by the company. It's a simple gesture but it works.
    Device itself
    Front of the device houses the headphone output, the volume knob, a 3.5mm audio input and switches for the XBass and 3D Sound. Unusually for a portable device a 6.3mm jack is used instead of a more common 3.5mm connection but iFi includes an appropriate adapter in the box so that shouldn’t be a problem. The potentiometer is wonderfully smooth to operate and the switches are sturdy enough to not be turned by accident so overall, great job. One issue that should be pointed out though is that the volume marker on the potentiometer is rather hard to see (a black notch on black background). iFi, please put a dab of paint in a contrasting color on the notch to make it more visible. That’s the only improvement I could ask for.
    On the back of the device we can find: USB used for connecting the USTAB to a PC or a mobile source, a pair of analog RCA jacks and a combo coaxial/optical input/output RCA plug. The combo RCA plug works as an optical or coaxial input when no USB is connected and as a coaxial only output when USB is connected, thus making the iDSD an USB to S/PDIF converter when the situation calls for one.
    USB port of the iDSD BL is unique among portable DACs. While all other products happily use the micro USB type B connectors, the USTAB not only uses a full size type-A plug, it uses a male USB type-A plug! Not gonna lie, I was very sceptical about this. What’s wrong with good ol’ micro USB type B? Well, lots of things actually. Micro USB connectors are unreliable, fragile, and easily broken. Also, DACs which use micro USB connectors require their own custom micro-USB to micro-USB cables.
    So, how do you connect the iDSD BL to a smartphone? Easily, using a USB OTG adapter (or Apple Camera Connection Kit if you’re an iPhone user). And you know what? This is genius. Think about it. OTG adapters (and CCK) can be found in pretty much any electronics store. They don’t need to be custom made or imported from China. And the connection is much more secure than a micro-USB type B connection.
    An unbreakable bond was formed
    Congratulations iFi. I will never, ever doubt your design decisions again. You have convinced me.
    The right side of the device houses a female USB type A port. This port is used to charge your mobile device. It’s not going to win against a dedicated powerbank but it will save your skin in an emergency situation. As I’ve said, iDSD is a Universal Soldier, able to adapt to any situation.
    Left side and the bottom of the device is where things start to get more interesting. Here we can find switches used to fine-tune the performance of the USTAB.
    • RCA output switch - Used to switch between fixed and variable output. use fixed output when connecting the iDSD BL to another headphone amp, a preamp or an integrated amplifier. Use the variable mode when connecting to active speakers or a power amp. Dunno what else to tell You dear reader, works as expected.
    • Power mode - used to switch between three different gain settings. Goes from “reasonable” to “no man shall possess this kind of power” really fast. The effect of the Power Mode on the overall sound quality will be covered in more detail in the part where I finally start talking about sound.
    • Polarity - Used to reverse the polarity of the digital signal. Despite my best effort I was not able to hear any difference between the reversed and the non-reversed signal so I just left it at non-reversed.
    • Digital filter switch - Used to switch between three different digital filters. Honest to God, I can’t hear the difference in PCM mode. In DSD mode the switch controls analog filters and the difference is clearly audible so I will cover it in more detail in the part where I finally start talking about sound.
    • IEMatch - Used to adjust output sensitivity. If you experience hiss even in Eco mode, adjust this untill hiss is gone, otherwise leave at Off.
    The bottom of the device also has output labels and the spec sheet printed on it but since it’s black writing on an equally black background you won’t be able to decipher it anyway. iFi please make the font at least a little brighter.
    Yeah, I don't know either what it says
    I was able to test the iDSD BL on Windows, Linux and Android operating systems. Unfortunately I do not have access to Apple hardware so I wasn’t able to test Macs and iPhones for compatibility. Here are the results:
    1. Android - PCM, DXD and DSD playback works using USB Audio Player Pro. All playback modes (Native, DoP, DSD to PCM conversion) are supported. Does not work with apps that use standard built-in audio stack (YouTube, Tidal, Spotify), however that is an Android issue and not iDSD BL issue. If you plan to use USTAB with an Android device please download one of several USB Audio compatible music apps or root your device.
    2. Windows - PCM and DXD works after installing iFi’s proprietary driver. DSD playback works in DSD to PCM conversion mode. I followed the Foobar2000 configuration guide but after setting up the plugins I ended up hearing either music in PCM-conversion mode or total silence in native DSD (both indicated via the Foobar interface and the color of the LED on the USTAB).
    3. Linux - PCM and DXD works systemwide out of the box (via ALSA). DSD playback works in DSD to PCM conversion mode. Unfortunately after a few hours of intensive cli-fu, googling and reboots I still didn’t manage to force MPD to play DSD natively so I just gave up. According to instructions I found here [TU LINK https://github.com/lintweaker/xmos-native-dsd] native DSD requires replacing the kernel and ALSA lib and/or applying custom patches to the MPD. As far as I know audiophile-oriented Linux distros such as Volumio and APLinux have this modifications built-in but I haven’t tested them myself because the amount of effort required to do that quickly got ridiculous.

    The part where I finally start talking about sound

    As usual, my first song is And Plague Flowers The Kaleidoscope by progressive black metal band Ne Obliviscaris. The violin intro on this song is my go to treble evaluation track. Throughout the entire song iDSD BL remained in full control of the sound. The violin was crisp, smooth and articulate, with absolutely no harshness to it whatsoever. What impressed me the most in this song is that despite the overall density of the mix the violin parts and clean vocals were always clearly separated from the other instruments, never blending with the drums or the guitars.
    Next up, Kraftwerk’s Sex Object. Probably my favourite track from the Techno Pop album. A clear motive is established at the beginning of the song, composed of violin-like synthesizer melody. This motive is played throughout the entire song, and just like the real violin in NeO, it remains crisp and articulate without ever sounding grainy.
    Last but not least, Nothing’s Gonna Hurt You Baby by Cigarettes After Sex, an American ambient pop group. Wonderfully detailed, airy with great imaging. The cymbals are deliciously crispy with satisfying decay.
    To mix things up a little I decided to play Sunyatta album by instrumental progressive metal band Vipassi. The guitar and bass are fast, forward and dynamic with good attack. Drums are clearly separated from the rest of the instruments and remain so for the duration of the album.
    Every note is clearly pronounced and every is riff full of life. On Benzeiten, the second track of the album, the USTAB gives the drums much needed impact without sacrificing guitar slam. On Samsara the backing female vocals can be clearly distinguished in the mix despite the very aggressive drum and guitar parts further proving that iDSD BL’s instrument separation is top notch. Frankly I don’t know what else to tell you, this album is a treat to listen to on the iDSD BL (if you’re into metal that is).
    But maybe you’re not that into metal and you’d like to find out how does the iDSD BL handle more audiophilly correct content.
    Let’s fire up Brothers in Arms. First thing you may notice is wonderful decay and pleasant smoothness of the guitar. Second thing you may notice is beautiful intimacy and depth in Mark Knopfler’s voice. It’s not that I’m suddenly hearing additional layer, I’m hearing the exact same voice I’ve heard numerous times before but it conveys so much more emotion than before. I love this song even more now.
    To properly asses the bass quality of the iDSD I must first tell you my dear reader about XBass.
    XBass is iFi’s proprietary analog filter meant to improve bass response of bass-shy headphones. But do not mistake it for a simple bass boost. XBass makes the bass more present in the mix, adds more body to it and improves impact (within reason, it’s not going to turn your AD700 into XB700). As a result bass-shy headphones become neutral-sounding or even “fun” and bassy headphones become… well, bassier.
    Test Track #1 - Almost Like The Blues by Leonard Cohen
    Great sense of depth on the bass guitar and plenty of detail but the notes do not carry any weight. Enabling XBass adds more weight and body to the bass. It is now as present in the mix as the piano and vocals. My Shure SRH1840 are now closer to being neutral than ever before. If I were to listen to Popular Problems only for the rest of my life, I’d probably never turn XBass off.
    Test Track #2 - Excursions by A Tribe Called Quest
    This song left me a little confused. After massive improvement I heard on the ALTB I expected the bass track to go through a similar transformation. But the difference was much more subtle here. Welcome, but subtle. SRH1840 were never a bass heavy cans and iFi’s analog filter didn’t turn them into such but it added some nice body to the double-bass intro as well as some more impact to the drums.
    Test Track #3 - What Happened by Dope D.O.D
    This is where the limitations of the filter start to show. Lack of sub-bass and very weak impact make this song lifeless using Shures. Despite my best efforts I can’t turn the SRH1840 into a bass heavy headphone. Of course it’s not iFi’s fault, XBass can put make-up and a nice dress on your prom date but it’s no Fairy Godmother. It won’t magically create sub-bass out of nothingness.
    As a last test I enabled XBass on my Beyerdynamic Custom One Pro, just to see how far the bass can be pushed on these cans. As it turns out,with XBass on the lowest frequencies get strong enough to cause the cups to vibrate to the rhythm of the music, in turn causing the bones in my skull to vibrate as well. Dubstep on this sounds like an earthquake deep in my brain. This was a unique experience to me and one I won’t forget anytime soon.
    3D Matrix Plus
    iDSD BL also has another filter called which supposedly recreates a speaker soundstage while using headphones. Initially I assumed that iFi’s description is just a fancy name for crossfeed but that seems to not be the case. While yes, the 3D Matrix Plus does seem to mix channels together a bit it also widens the soundstage, enhances the treble (subtly) and moves the sound above the listener’s head. Unlike the XBass I wouldn’t recommend having it on all the time but on some recordings (such as Yosi Horikawa’s Wandering) I really enjoyed it.
    Universal nature of the iDSD BL shows itself again in the Gain management section of the device. Most competing devices do not offer any type of gain adjustment or might offer a single High/Low toggle. But not USTAB, no. Our Universal Soldier is capable of using any weapon he finds on the battlefield no matter the impedance and sensitivity.
    There are three different gain levels available with additional adjustment available via a separate IEMatch switch on the bottom of the device. You plan to use 600ohm impossible to drive monsters with the BL? Go ahead, set the gain to Turbo and enjoy over 166mW of power. Oh, you’d rather use sensitive IEMs? No problem, set the gain to Eco and enjoy pitch-black background. What? You can still hear noise? Enable IEMatch to fix the issue. Still can hear it? Well, you might just have tinnitus because with IEMatch engaged the background of the USTAB is absolutely silent with not a single hint of hiss.
    Digital filters
    Last of the (many) switches on the iDSD BL. The digital filter. I’ll talk very briefly about this one because the difference is very, very subtle. When playing PCM files the difference is so small that I wouldn’t be able to distinguish between different filters if my life depended on it so I just left it on Bit-Perfect and never looked back.
    During DSD playback the switch toggles between three analog filters and switching between them seems to increase/decrease the volume of the track. I’m not entirely sure why this happens and whether it is supposed to do something more but the difference in volume is obvious. As with PCM, I left it on Bit-Perfect and never looked back as I find the option to change the filters rather redundant.
    Dear reader, if you've managed to get this far you’re probably under the impression that the iDSD BL is a perfect device, devoid of any defects and for the most part, you’re right. But unfortunately the USTAB does have some issues and this is what we’re going to talk about now.
    The first problem is that for some reason, iDSD BL mutes the first second or two of every track. This happens regardless of the file being played, source device and any of the iDSD settings. It’s not a dealbreaker by any means but it’s annoying enough to be mentioned. Hopefully this bug will be resolved in a future firmware update.
    Second issue: channel imbalance. At low volume (9’o clock on the potentiometer and below) the left channel is noticeably louder than the right channel. Increasing the volume resolves the problem but people who like to listen to music queitly (or use very sensitive headphone) might be bothered by it.
    Third issue: Size and weight. The USTAB is advertised as a portable devices that can be easily paired with a smartphone and while that’s technically true the iDSD is too big to fit in a pocket and it weighs a whooping half a kilogram when stacked with my phone. Trust me, I wish I was kidding.
    Portable device lol
    So, after seven pages of B-list movie references, jokes and babbling, what is my final opinion on the iDSD BL? I deeply enjoyed using this device both as a desktop unit and on the go. I deeply enjoyed its powerful headphone output. I deeply enjoyed its rich customization options. If you’re looking for a device that’s excellent in every possible use case, that can adjust to any headphones, any source device and any conditions you should seriously consider buying the iDSD BL. It is a brilliant device and a true Universal Soldier of the Audio Battlefield.
    Final note
    You may be wondering why I bothered to put all the goofiness here. Well, for me audio is all about having fun and I can't have fun if I'm forced to be dead serious.

      I don't find channel imbalance that much of an issue since you have pretty much 6 settings for gain (3 power/3 IEMatch). Even on the Andromeda, I don't have the volume low enough to notice imbalance.
      One issue I notice is a pop when it is turned on or volume dropped to zero, that one can be annoying and a good reason to not put your IEMs/headphones on before turning it on.
      Good work on the review.

    The only acceptable replacement for the most discerning audiophile's desktop stereo setups.
    Written by vapman
    Published Feb 19, 2017
    Pros - Crazy amounts of power, beautiful sound, portable, doesn't require drivers to work.
    Cons - Can't buy the special edition opamps on their own, costs money, will make your other gear suck in comparison
    The original iDSD Micro stood out from the competition as an all-in-one replacement for the most discerning listeners' setups. The original iDSD Micro delivered - I had one, but as I started to not need a portable device anymore, I started comparing it to all the dedicated desktop gear I had. I had a glorious DAC and some very serious stereo power amps at the time - two Hafler DH500's running in mono. By the time I had re-configured my listening station to be all desktop again, my iDSD Micro didn't have much of a place since my desktop DAC - an E-MU 0404 with an AK4396 - could do the job. That was the end of my time with the original iDSD Micro. I sold it and moved on. However, after almost a year since then, I had completely dismantled my home stereo as a result of living in an apartment and getting too many noise complaints. That began my journey to find the setup the could replace that stereo with no compromises.
    The new iDSD Micro Black Label is iFi's first major upgrade to the iDSD Micro. The very day I heard there would be a tour for it, I signed up and was ecstatic to find I had been one of the chosen reviewers for it. My hopes were that the Black Label wouldn't just match my crazy desktop setup - which could double my power bill just by being plugged in - but make it all seem lame in comparison.
    I have gone thru tons and tons of gear in the decade or so I've been on Head-Fi. One of the few things that's been consistent in almost that whole time is one of my first big audio purchases - an E-MU 0404 USB I got shortly after it came out. So it's been in my hands for close to 15 years. It featured a beautifully implemented AK4396, and for a long time (up until maybe 2012 or 2013) I used it as my headphone amp too. It was the DAC that survived not only the original iDSD Micro but even the mighty Mojo.

    Another one of my favorite DACs, although not a super expensive one - the Sound Blaster X-Fi Titanium HD, like both the original and Black Label iDSD Micro, uses a Burr Brown DAC. I always found the SBX effects to be high quality on it. Since getting rid of my original iDSD Micro, I would switch between these two DACs. I ended up being a huge fan of the bMac, an Indonesian made & designed portable amp, which has kept its place on my desk for close to a year now. I had also gained a very strong affinity for the Parasound Zamp, with the gobs of power it could push to any headphone, and sound amazing doing so. After the tour was announced, but well before I received my unit, the Walnut V2 made its appearance on the Head-Fi map and became well respected as a very high quality but budget unit. Having a power output comparable to the iDSD Micro, I decided to settle with it as I liked its sound even as a desktop headphone amp.
    Fast forward from the ending of 2016 to early February 2017. After a couple months of hearing nothing, and watching iDSD Micro Black Label reviews slowly pop up on the site - which I kept myself from reading to keep from having preconceived notions about its sound - I finally got the email. It was my turn at last to try the Black Label. Little did I know it would make me feel like the first day I got the E-MU instead of listening with my PC's built-in sound chipset, or the first time I heard $1,700 IEMs - you get the point.
    The day it arrived, I got both my most recent favorite setup and the setup that beat the iDSD Micro many months ago, and got them ready and re-familiarized myself with them before switching to the Black Label. I don't even remember what headphone I tried first on the Black Label. The thing is, it doesn't matter. No matter what I tried, it was on a whole different level than any of my gear. My setup that had been my favorite up until that moment was dishearteningly muddy and flat in comparison to what I was hearing. The setup that nearly matched the original iDSD Micro in sound was lifeless and lacked dynamics compared to the Black Edition. And so, that marked the last day I was able to enjoy the setup I had until that point.
    I knew the Black Label was all business. Custom-designed op-amps, a stunning capacitor selection, and some awfully bold claims about how much better it would be over the original. While I can't rip the op-amps out of this tour unit to try in other gear, and I doubt iFi would sell me some of their iFi/AMR op-amps, I've messed with enough op-amps in my life to know what to expect from a lot of them, and I know from my time with the Black Edition I like what I am hearing an awful lot.
    A while back, I published a review on the Parasound Zamp, a 45 watt zone power amp that happened to have a headphone jack on the front of it. I praised it for its ability to breathe crazy amounts of life into any headphone you plug it. People got excited about it, and it was one of my most popular reviews. I've tried other amps that boast a high wattage output, but none are capable of being quite as dynamic and effortless as that Zamp did. Even if the original iDSD Micro couldn't do this job, the Black Edition definitely can and does. I think I spent at least 3/4 of my time with it in Turbo mode. I'm a bass head, a SPL freak and I love my headphones to sound like they're going to explode with energy. I could not find a headphone pairing that did not sound good on this amp, much like with the Zamp. And for how alive, crisp, and clear everything sounds, I probably would have been impressed if I was just hearing the amp section and didn't use the DAC at all. Using the original iDSD Micro I never wanted to use as an amp by itself, but the Black Edition has me enjoying the device as an amp thoroughly.
    Speaking of bass - one of my bigger complaints about the original iDSD Micro was the bass boost switch hardly did anything. It made a very subtle difference which I felt was only really noticeable when you were listening at very high volumes. I was pleasantly surprised to hear that the bass boost was certainly more present on this unit. On any headphones I used, it added a great amount of weight to the bass with any headphone I used. The background is silent and the detailing and clarity is top notch. When I was listening with more demanding headphones like the JVC SZ's, the difference was huge with the switch flipped.
    The 3D option does roughly the same thing as the Sound Blaster's Crystallizer function. It essentially makes the sound a little more "V" shaped. I kept the 3D switch off for the majority of my listening, but never thought it sounded bad with it on. I don't tend to use the Crystallizer very often at all when I'm using my X-Fi anyway. What is clear is that the Black Label goes so much farther past the all-in-one replacement for your listening setup. For discerning and picky listeners who are not willing to accept any compromise, true music lovers who listen all day and can't tolerate a minute of downtime, this is the all-in-one unit for you.
    The price and its similarity to the Mojo's price can not be ignored. The original iDSD Micro used to be compared to the Mojo, but I never felt that was a balanced comparison, even if they did the same jobs. Interface differences aside, the Mojo has a more unique sound. For me, that unique sound did not always work out. It made my MP3's and other lossy audio sound like garbage. Lossless sounded wonderful on the Mojo, but I don't have the kind of library that can be easily replaced with lossless copies. The Mojo failed to work out for me for this reason, regardless of the fact the volume control balls drove me insane and the charging mechanism was too flaky to work for someone who listens all day long and gets furious at any downtime. My Mojo only lasted a couple months before the aspects of it that bothered me outweighed my ability to enjoy it.
    The Mojo is more easily compared to the Black Label, I think. Lossy audio still sounds great on the Black Label, but the Black Label - even on bit-perfect mode - offers such a fast and detailed yet slightly warm sound. I always felt the iDSD was the more honest of the two, and the Black Label is the best choice for me as it's honest, neutral, and balanced but offers the lush, refined sound the Mojo was capable of whereas the original iDSD Micro was not as capable. Before the Black Label, I think it would have been a much harder choice between the Mojo and the iDSD Micro. With the Black Label in the mix, the gap is so much smaller. The improvements iFi brought to the table with the Black Label really shows. No longer do you have to pick between two desktop stack replacements which approached the problem in completely different ways for a great all-in-one portable device. I noticed right away the overall sound character has tried to catch up to the competition, and it is my opinion that iFi did an excellent job of this. Anyone who thought the original iDSD Micro could stand to be brighter would probably not be the biggest fans of the changes iFi made. To anyone else, I would feel pretty confident it is only an upgrade. It's a move slightly more in the direction of how the Mojo sounds, and personally I like it a ton.
    To be sure I get my point across by how impressed I am of the sound coming out of this device - all-in-one unit or not - my DAC and amp setup I had been using before this, I had replaced op-amps, capacitors, all manners of things to improve the sound quality to my liking. And while it all had approached and come fairly close to the Black Label's sound, it just simply can't catch up in any way. My setup had too much background noise and not a dynamic, crisp and quick enough sound to it. It was even a tiny bit like I was back in electrostatic territory listening to the Black Edition at times. I wasn't even happy with my setup's bass levels when I was switching back from the Black Label which took me by surprise. The bass power of the Black Label is not to be underestimated. 
    On the day I got the tour unit, I was doing recording work in my studio and had it sitting on top of a tube compressor I was using. Of course, it made perfect sense that once I was done recording and going to listen back on headphones, I should first listen with the setup I had deemed best, and then listen straight out of the Black Edition.
    In my pitch-black recording studio, I noticed the iDSD Micro BL illuminated by one of my tube compressor's VU monitors.
    Listening to the Black Label has made me so uninterested in all the other DACs and amps I have lying around. They all are so inferior to the Black Label in my mind now. Every headphone I have tried it with, it's a gorgeous, lively pairing. There is no such thing as bad synergy with the Black Label. Everything works so amazingly with it, and the Black Label is able to make anything I throw at it - source material or headphones - sound the best I've heard most of it ever be.
    While it did not provide a whole new world of clarity I hadn't heard through my DAC before, it did give me something I hadn't heard since that dual mono Hafler setup with the 0404 sitting on top. That dead silent background, perfect extension across the full frequency spectrum, no BS. All you got was the music, honest as possible, but sounding beautiful doing so. It is a gorgeous thing when there is truly no need for any tricks to make the source sound better than it really is. All you need is the perfect presentation of it. My years and thousands of dollars per year spent chasing this level of sound proves this was no easy feat. 
    One of the other things I wanted to test out of the Black Label right away was its performance as a DAC if substituted for either my 0404 or modded X-Fi Titanium HD with the same amps afterward. The dual mono DAC design had me very interested in this model. It had lower noise and better detailing, speed and dynamics compared to the X-Fi Ti HD. Compared to the 0404 with the AK4396, the 0404 was a leaner and brighter sound. It did not have the slight warmness the dual Burr Brown setup in the X-Fi, but the 0404 also had a thinner and flatter sound in comparison.
    The last time I've had this hard of a time giving up some review gear was when I was touring the Kumitate Labs IEMs. I never ended up getting one of those were too far out of my price range combined with my unwillingness to buy a custom IEM, with the KL-REF being close to $2000. Still, to this day it remains one of the most beautiful and well balanced sounds I've heard from any headphone. Going back to my gear after sending the Black Label back to iFi I know will feel like sending those Kumitates back. I just wanted to keep begging to spend another day with them. I had to force myself to keep listening when I was comparing my other gear to the Black Label because none of it was as good. None of it. I knew it was a winner when I couldn't stop trying different headphones through it, not because any of them weren't giving me the sound I wanted, but because they all sounded so ridiculously good out of the Black Label. I had been using headphones I hadn't tried in ages just to rock out because they all sounded so much better than I had remembered them. This isn't something I had done or really experienced since I was doing my Parasound Zamp review.
    I had been struggling to find out how I was going to describe this device adequately in a review. I wanted to do it proper justice, not just say over and over "it was great! i loved it! everything was great!" and after several drafts I still have the feeling my whole review just reads like that. What I can't seem to emphasize properly is how to put my experience having the iDSD Black Label into the proper context.
    Finally, the answer came to me on the weekend at 4AM. I was standing in my living room in my pajamas, JVC SZ2000 on my head, the iDSD Black Label in my hand, running off a super long USB extension cable into my PC. I had been tweaking my five-band parametric EQ and blasting crappy Italian Discomagic compilation CD's from the early and mid 1990's. I remember because I had Turbo mode on the Black Label and was pushing every last decibel of sub and mid bass out of my JVC SZ2000 as I could. As I was listening to the cheesy Italo disco mixes, I went back through all the Head-Fi meets I'd been to in my life and came to a realization. The most active meet I'd ever attended, which was in 2006, I listened to all the top of the line setups that existed eleven years ago. Nothing I was hearing was possible back then. Forget the bass power of the SZ2000 which just wasn't possible before JVC invented that - what about the Black Label itself? As a perfect stand-in replacement but not more than that, the original iDSD Micro was still a feat of technology that wouldn't have been possible in 2006, but I never got the impression with the original iDSD Micro that really took me by awe. The Black Edition was something that truly was not possible as long as a decade ago or even half a decade. Here was a box I could hold in my hand and not only could it match the sound of stacks of gear amounting to nearly $1,000 on their own - it was surpassing all of it in any possible way. Going back to any of my old setup results in one form of disappointment or another. And anything I heard that long ago, giant stacks of specialized gear isolated from one another and linked up with top of the line cables, to my own personal setup I've obsessively perfected over time, all crushed by the sound of the Black Label. This was truly the sound of audio perfection as far as I've heard. Maybe it won't be 5 years or a decade from now, that's fine because it's good enough to have turned the tables. I can shamelessly say this is what I hoped the Mojo would be. Not only having enough power to challenge the most power hungry headphones but sounding so glorious doing it, there is nothing else I could ask for.
    The Sound Blaster seemed so worthless in comparison. No DSP can come close to matching the sound of bit-perfect music played so honestly, with so much perfectly controlled power. The E-MU could only compete when it was running thru the Zamp V3 - still one of the most amazing and perfect combinations I've ever heard in my life - but this offers so much more flexibility and doesn't require two AC outlets. That is what truly made this device so good to me. The sound quality and energy I could only get my running my all-time favorite DAC into a 45 watt desktop power amp, designed to drive speakers, with a gigantic toroidal transformer. The DAC also requires its own power supply. Two pieces of gear I had never been able to beat with anything bus or battery powered. And here it was! Worst of all, it wasn't even mine - I was last in line for my leg of the tour. I would go in between dancing and singing to these bargain bucket Italo house mixes and complete despair that I had to give it back to iFi. I just couldn't stop listening to it, day or night. Every minute I spent with the sub and mid bass boosted as high as 34dB and Turbo mode activated with my JVC's was to die for. And, yes, it's suitable for non bass heads too. More often than I could understand, I found myself with Turbo mode on but running no EQ and just having the XBass switch on with all my power-hungriest ear buds. But again I have to emphasize, it doesn't really matter what gear you use on this. No matter what it is, it's going to sound as good as it can possibly sound in the year 2017 as far as I am convinced. I spend thousands of dollars on gear per year chasing after this exact sound. I have no doubts that the Black Label is a turning point, as it would be remarkable even for a desktop only device in my opinion. To be in a battery powered, compact format is nothing short of mind-blowing, and the components that are upgrades over the original iDSD Micro enough to make any audio loving engineer shed a tear of delight.
    Is it worth your hard earned money? I would feel better about getting this than I ever did about buying a Mojo. I could just have this and my PC running foobar2000 and I'd be set. There is nothing I could find lacking in this device compared to anything else I like to use to listen. In fact, the Black Label really brought out what was wrong with the rest of my system. I was worried if I liked this a lot I wouldn't be able to budget for it even if I stretched it, but my experience using this has completely and honestly made the rest of my DACs and amps seem useless. At this point, they are all inferior to the Black Label in my eyes. When I send it back to iFi, I'll be counting the days until I have one in my hands again. Really, after about 2 weeks spent with this unit, I haven't been able to bring myself to use anything else for more than a couple minutes. It's the new standard by which I will measure anything else, truthfully and honestly. I can only hope I don't have to go too long without it in my life. I've had iFi gear before but I'm fully convinced now they're entirely deserving of all my respect. I can't thank iFi enough for the opportunity to try this out, even if it did make me hate all my other DACs and amps. For a single device to be able to replace what I missed most about my 500 watt dual mono-block home stereo is truly remarkable. For it to be battery powered and pocketable is truly ridiculous. I do honestly think this is a new milestone in portable sound. Anybody else making combo DAC/amp units needs to take a serious lesson from this. iFi is not messing around and it is so obvious when you are listening to it. I can't help but recommend any lovers of that lively, energetic sound prioritize investing in this unit.
    (edit: I realized I never mentioned my settings used. For nearly the entire time I had this, as with my original iDSD Micro, I had IEMatch disabled and the filter set to bit-perfect. Also, I failed to mention the IEMatch switches are more recessed than on the original iDSD Micro, which I appreciated.)

    ifi Micro iDSD BL (Black) review​
    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....

    Whats in the box?
    The unit, warranty card, instructions etc​
    An excellent array of cables and accessories.​
    The unit itself.​
    `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.​
    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.
    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.​
    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?
