iFi iCAN (Standard and SE)

Power in a small package.




For those who have read some of my past reviews, you'll notice that I've changed up the format slightly.  Graphically, this new review format looks more appeasing to the eye, while writing wise, I find that it is more fluid and natural.  Hope you don't mind it too much, and feedback is appreciated!




As a somewhat regular visitor to Stereo (audio store here in Singapore), I’ve caught more than a few glimpses of iFi’s sleek product lineup.  Svelte metal enclosures, tactile switches, and the wonderful iFi logo all exude an air of premium utility.  Packed within these enclosures are trickle down components and technologies from AMR’s (Abbingdon Music Research) higher-end products.  Rather compelling indeed –surprising that I hadn’t given these an extended audition. Until now, that is.  Sitting on my desk are the original iCAN and the iCAN SE.  Before going further, I’d like to thank iFi Audio and Stereo Singapore for providing me with a loaner unit of the iCAN SE for this now overdue piece.  The iCAN was purchased subsequently, and might I add, independently.  As before, I am neither an affiliate nor an employee of iFi or Stereo, and all media in this review is owned by me.  If you’d like to reproduce it, or have any questions in general, feel free to drop me a line. 



The iCAN is a Class A “Tubestate Amplification” hybrid (or as iFi likes to call it, tri-brid) amplifier.   It is currently available in two models: the standard and special edition.  There are several differences between the SA and SE editions.  The SE features boutique components, an updated “sound signature”, refined XBass and 3D Holographic Sound, increased output power (from 400 to 4000 mW), new gain settings, and a brand new iPower.  Rest assured, I’ll cover how the standard and SE compare in the coming paragraphs.   


SPECIFICATION  iCAN Standard         iCAN SE                 
Gain 0, 10, and 20 dB 0, 12, and 24 dB
Signal To Noise Ratio >117dB(A) >123dB(A)
THD <0.003%(400mV/150R) <0.003%(400mV/150R)
Frequency Response 0.5Hz to 500KHz(-3dB) 0.5Hz to 500KHz(-3dB)
Output Impedance <1 ohm <1 ohm
Output Power >400mW(32Ω) >4000mW(16Ω)
Output Voltage >5V (>600Ω) >10V (>600Ω)
Input Voltage AC 100 – 240V, 50/60Hz AC 100 – 240V, 50/60Hz





Packaging wise, the iCAN comes absolutely stocked right out of the box. Rubber feet, matching RCA cables, a 3.5 to 3.5 cable, jack adaptor, small screwdriver, quick start manual, warranty information, and the unit itself.  The overall unboxing experience feels premium, and is reminiscent of the excellent product packages made more commonly for Mac products.  The best part though is that all the accessories are well thought out and have good grounding in utility, and there’s nothing excessive or wasteful about it.


The design of the unit is similarly excellent.  The rectangular metal enclosure is non-obtrusive and well made, but is also surprisingly light.  Without the included rubber feet, the unit slides around quite easily, which is somewhat troublesome.  The switches are well-made, with a solid click to them.  However, the volume pot doesn’t feel quite as substantial as the rest of the unit, especially when compared to my DACmini.  The upside is that the iCAN is easily transportable.  Keep in mind that it will require a wall outlet for operation (look to the Nano series for battery-based portable devices), but if you’re looking for an amplification solution that is also both discrete and space-conscious, the iCan is the right way to go.  Overall, the iCAN is a well-made piece of kit that succeeds both packaging and design wise.




iFi Audio has packed a ton of features into the iCAN.  This wide array of options is rather intimidating, and filled with extravagant terms like XBass and 3D Holographic Sound (sounds more like something you’d fine on a soundcard aimed at gamers).  Don’t be put off though. The iCAN is strictly business, and I found a number of its various features to be impressive.  I’ll cover them one by one, and share some insights on their respective utilities and functionalities.  Nearing the end of my review though, I did notice that my iCAN SE started giving off a “buzzing” sound.  I do suspect that this is just an issue with my unit, as my own iCAN did not have this.  I will have to check more closely on my power supply, though I don’t think that’s the source of the problem.  Nevertheless, I was able to get a fairly good sense of the unit's capability prior to this, and with music playing didn't notice it all that much.  




Let’s tackle the XBass first.  After all, everyone could use just that little extra bass in their lives.  I found the XBass to overall be a rather impactful, but tactful bass bump.  It focuses on the lower-mid to subbass region, providing more of a grumbling “under-your-skin” boost that plays well with most headphones.  Both levels worked equally well, and it simply depends on the listener’s sound signature preference.  The standard edition has a more forward XBass boost, but one that is lesser in quantity and less enveloping than that on the SE. For me, there really wasn’t all that much need for bass boost anyways, but it'll come down to personal preference.




I was somewhat skeptical when I first came across this setting –especially about its efficacy.  A small introduction for those who are unfamiliar with the feature.  The idea behind 3D Holographic Sound isn’t entirely new –at its heart, it is iFi’s take on crossfeed application in a headphone amplifier system.  Crossfeed is the blending of right and left channels to create a more cohesive sound image, something that is naturally occurring in most speaker systems, but rather limited in headphone settings due to the physical structure.  Older implementations often featured disruptive digital processing, something iFi is quick to point out.  In contrast, the iCAN utilizes only analog processing.  The first setting for the 3D Holographic Sound didn’t stand out that much to me.  The center image was quite strong, and it was obvious that there was blending going on.  However, the iCAN shined when put to the second setting. Headspace becomes an empty vacuum, and the general image is expanded forward and around the listener.  The end result is excellent, as the sound image becomes an audio panorama (excuse the rather unwieldy comparison).  Ensemble jazz/classical pieces work great with this feature.  Vocal tracks are for the most part, excellent as well.  One never gets the sense that items are too far apart on the soundstage, and I left this feature on most of the time.


I will say that I preferred the SA’s 3D Holographic Sound feature to that on the SE.  I found it to be airier and more spacious, whereas the SE was smoother but less immediately striking. It didn’t quite have the same sense of expansion as the SA does. Both implementations (on the second setting) are excellent though, and I would heartily recommend purchasing an iCAN simply to give the 3D Holographic Sound a spin.




The iCAN is a clean, albeit slightly warm, amplifier.  It features an excellent amount of power, driving the T1 to fairly uncomfortable levels very easily (at around 1 PM is enough to make one cringe).  It also played very nicely with my R70X and M50X, especially with the 3D Holographic Sound which opened up the sound signatures of these two relatively “closed” headphones.   Do not be fooled by the unit's diminutive size -it drives with serious authority. I personally found that the iCAN SE was more closed, intimate, and fuller sounding, whereas the iCAN standard was more strident and airy.  It’s more a matter of personal preference, but I found both amplifiers to be very agreeable with most headphones.   Both amplifiers will work with IEMs, though there is noise on the more sensitive ones and you do get very little play on the volume pot.




I did enjoy my time with iFi quite a lot. It's a great amplifier, and its features are truly well implemented and do provide a meaningful value added.  If you're looking for a new headphone amplifier, I'd heartily recommend the iCAN.  It's discrete, well-built, and most importantly, sounds excellent. I must say that a purchase to test out the 3D functionality alone would be warranted.  Put simply - there's a lot going on at a highly reasonable price point, and iFi did a job well done with this amplifier.


Thank you for the nice review, and the format is very readable and certainly user friendly. I have recently purchased an ifi iDSD Micro and I concur with your impressions such as they can be compared. Cheers.
Great review.!
I have to mention the buzzing. I had two iCAN SEs. My first one had buzzing, so thinking it was a defect iFi exchanged it. The buzzing went away but then reappeared in the replacement unit. Shortly there after the iPOWER died. So in the mean time I am using a 12V 2A power supply brick unit from a hard drive enclosure and the buzzing has yet to come back. In fact, even at high gain with the brick unit there is ZERO noise, just pure blackness. I think there was a bad run with the iPOWERs, or a flaw with the adaptor plugs for non-UK residence. Once my replacement iPower arrives I will know more.
I also experienced buzzing noise, with 9v HDD PSU it's gone. My iPower also died, I'm waiting for the replacement.
Anyway - SE sounds great and the review is great.
@Sonic Defender iDSD is really nice...something that I hope to perhaps to get in the future.  Glad to hear that the format worked as well.
@Bansaku Thanks for the heads up... it may indeed be something wrong with the iPower.  
@Vanquished Seems like this is indeed a recurring problem.  A bad run as Bansaku said may be the cause.  Glad that you liked the iCAN -great little device.
Are you sure the iCan SE outputs >4000 mW @ 16 ohms?
Jeez, it does.  That's crazy amounts of power.
@Uberclocked - yup it can do that.  Whether it is necessary...depends on user I suppose.
A very enjoyable review...I like the style. Flow is an accurate descriptor...I felt like you were able to give a lot of info without feeling overwhelmed. This amp is on my list (this, or if I want to go DAC as well, the Micro IDSD, the Grace Massdrop, Mojo & JDS Element are all under consideration)
@jinxy245 glad to hear that it worked.  You could also try the Centrance dacMini for a DAC/Amp combo as well.
Thanks, I'm a big fan of these, I have the original Ican and I couldn't be happier with them. Yes the 3d holographic circuit is a huge boon here, and it is engaged all the time for me. Never noticed any noise but then again I don't have any IEMs as I don't like them for comfort reasons.
@LajostheHun Very glad to hear that you like the iCAN.  It's really nice. I suspect noise is coming from the iPower (unconfirmed).
Okay I read that wrong - I thought you meant the buzzing.  Sorry.  Noise wise there is some on certain IEMs.  Not that I'd use them with an amp regularly anyways though.
@thatonenoob Thanks for that...the Centrance does look interesting... I haven't read enough about it...and the Apogee Groove is supposed to be good.
I have a little more reading to do!
Thanks again
Just bought SE version. I have wondered about one thing. Is anyone else noticed that right channel is silent until you turn volume louder? If you turn volume off and then start to turn it up, I hear music first from the left channel of the headphones. Should this amp work like this or is it somekind malfunction? I have Sennheiser HD650 headphones.
@mtr1 This is common on virtually all analogue volume potentiometers, and is nothing to worry about.
Ok, thank you. I thought that it would be something like that.
I have to return to my problem with the SE amp (left channel plays louder than right). It troubled me so much, that I told about this to retailer and he asked about this problem from Ifi Audio. Ifi was interested to get this faulty unit and I got the new one. And, yes, this new one sounds like it should. Retailer thought that problem is in gain adjusment switches or something like that. I hope that I get also the answer, what was wrong in the amp I first got. And sorry my english, not my native language.
I recently sold my iCan, only because I had too many amps & something had to go. Still, I was impressed with the competence, flexibility, and portability of this amp, particularly at its low price point. The tone adjustments IMO were "icing on the cake" -- I ended up not using either (I'd rather get bass from the headphone's design than an amp circuit or EQ; and I really didn't hear much diffence w/the 3D control), but it's nice to have them. I see the iCan as a killer entry-level HP amp. You have to spend 2-3X its cost to really move up in sound quality.
