Kitsune Holo Audio KTE May DAC by David Abramson



May Day!! May Day!!

“As to R2R DACs, they are extremely simple to build. You can build one yourself if you just search a bit online! Getting them to be low noise and distortion is much harder.” It’s my favorite objectivist Amir, chief measurer and orchestrator over at, posting.

Well, it would seem it’s much MUCH harder as, per ASR, it’s not often achieved. R2R (measurement) failure abounds! Further along in the thread; the one that talks about how well the Kitsune Holo Audio KTE May R2R DAC measures, we happen across an objectivist unfortunately named VeerK (probably not his real name) who writes “Nice; good job to Holo Audio for engineering an R2R DAC that finally measures with the big dogs. Very curious how folks over on those other forums will try to describe this DAC with their flowery words. A DAC with their ‘magical’ R2R that measures well might make their heads explode.” 

Flowery words!? Exploding heads?!! Exploding Kittens maybe (it’s actually a fairly challenging card game); but flowery words indeed! Mine are buttery-soft and flakey like a good croissant! Some people…

Well those ASR guys will be happy to know that for this review I blindfolded myself to begin the blind ABX testing portion and then… promptly tripped on Brandy (my cowhide rug with the visible brand) and fell into the wall almost toppling over my Design Within Reach Pablo Elise acrylic and stainless steel halogen lamp in the process (which by the way, gives off exactly the same wavelengths of light as a 10 dollar halogen lamp from IKEA!). NO I haven’t measured!! I can just tell! Without this stupid blindfold that is.

NOW do you see why we reviewers HATE blind testing!!?? It’s a stupid idea in a small room with furniture. You almost kill yourself every time plus you can’t find your friggin’ listening chair!

Origin250.jpgAlso, if everything that measured similarly sounded exactly the same, do we still have a hobby here? I mean, what’s the friggin’ point?! Lets just go bass fishin’. Perhaps Julian Hirsch was right long ago in Stereo Review and it’s all the same. Maybe I DON’T really prefer the Audioquest Carbon USB cable to all the others I’ve heard and I just think I do. I dunno. Maybe let’s just have a scotch and forget this whole listening thing. Matter of fact, forget the Holo Audio May KTE DAC under review here. One sec… I’m gonna Duckduckgo R2R DIY and see if I can pull this off myself. How hard could it be?  Let’s see here… resistors; gotta match those. Closely. Some sort of power supply and a cord… A few FPGAs and maybe go on Fiverr and hire a computer programmer to handle the coding there, and then… On second thought, let’s let experienced audio and electrical engineers who know what in hell they are doing have a go at it, shall we?

Now then… my short-lived DAC designing dreams aside, preliminary research (Google) seems to suggest The KTE May is one of the few DACs about which objectivists and subjectivists alike are united in their praise.

Whereas previously one group thought the other cretinous ninnies and the ninny group in turn thought the other egg-headed dotards who never actually listened to anything and couldn’t do a single push up, perhaps this DAC means they can lay aside their differences and unite for the betterment of all, following closely the example of United States politics.

Too much to hope for? Well, one can dream. So long as you precisely measure the synchronicity of the fronto-temporal brainwaves that are hypothesized to result from said ‘dreaming.’ I suppose the real parallel question is why would anyone want, say, a tube amp that measures perfectly flat and sounds exactly like a solid-state amp? Just buy the solid-state amp! Less heat/less mess! 

No; tube amp buyers generally want at least a trifling amount of ‘tube’ amp sound; the ‘distortions’ known as tone, space and weight that comes part of the deal. Take those things away and you’ve got a space heater that works slightly less well than an 88 dollar one you can have delivered tomorrow from Bezos and which sounds exactly the same as a ruler-flat-measuring entry-level Sony receiver; which I suppose, is the objectivist’s theoretical ideal?Sheesh. 

Maybe we DON’T have a hobby?! Or maybe audiophiles have sonic preferences based on what they believe their recordings should sound like to THEM and don’t all want to hear precisely how bad certain recordings are and all the artifacts on the good ones. Maybe, since they are not in charge of mastering them, those phenomena actually get in the way of their enjoyment of this so-called hobby; i.e. listening to music for enjoyment and the pursuit of the ideal collection of boxes there for.



Entry level Sony receiver which very probably measures perfectly on ASR

Listen; don’t listen to me! I’m still recovering from my ill-fated attempt at blindfolded testing. My head is spinning. Listen to the Kitsune engineer who goes by Bimmer100 who writes on their website, “Here, we can see that, for audio, we should understand that the audio industry’s existing measurement spec. can not correspond to people’s listening experience. We are not able to use those numbers to quantify our listening pleasure. These specs tend to be analyzed from the [standpoint of] completeness of the content. However, this is not the case for human feelings. [There is] complete information, but the order of the [content] will have disastrous consequences. Likewise, more information is not meant to be better than less information, and [in] a well-designed non-oversampling DAC, we will find richer and more natural details.” Wait a minute! Just which side are these Kitsun-ites ON!!?

Possibly the same one as Peter Lie, Lumin audio firmware lead engineer who says elsewhere on the interwebs, “Arguing whether something should sound better or not based on some theory is usually futile. The important thing is to hear it.” And this Lie guy has the audacity to call himself an ‘engineer’!? Hashtag Sick!

Well then can we? Have it ALL I mean? Our NOS and our R2R and our hobby and eat it too?


One DAC to find them and in the darkness… (possibly) bind them?

Gtt 2018a.gifThis is a two box affair. Well, it’s one single shipping box with two smaller boxes inside, one containing the May’s brawny power supply and one containing the May’s well-measuring brains and by the way it’s damnably heavy. Like amplifier heavy. The back pain sufferers among you should consider yourselves warned! “I’d like Amir to measure the friggin’ weight of this thing,” I mumbled to myself. I sat the brains upon the brawn as instructed, connected them with a DC cord and in process could not help but admire the beauty of the coppery keen side panels and how they complemented the coppery keen buttons up front. These buttons let you select your source, select whether sound is processed or un (non-oversampling mode, oversampling etc.), toggle the display on or off, mute the unit and of course, turn it on (however you will take that).Did I mention the two boxes together are heavy? They are. Bend at the knees!! The May KTE represents the maximum topped-out level May (above the L1 and L2 models) and features an absolute panoply of designers’ dream parts like silver wiring, custom made and reportedly sonically preferable KTE-only special capacitors and tighter tolerance DAC modules “hand selected to have the best measurements compared to averages.” It also has my favorite upgrade; the Titanis 2.0 USB input module which is reportedly superior to the XMOS xu208 featured on the lower end Holo Spring 2 DAC and on the base model May.

Now, by way of comparison, the first stanza from Wallace Stevens’ The Bird with the Coppery, Keen Claws:

Above the forest of the parakeets,
A parakeet of parakeets prevails,
A pip of life amid a mort of tails.

Stevens was a legendary abstract poet who worked his entire career as an insurance executive at the Hartford Accident and Indemnity Corporation! A better comparison to the May DAC I cant conjure…

Anecdote has it he would dictate some of his memorably abstract work to his assistant on his way out for the day. I can imagine him in pre-Covid times maskless, putting on his hat and coat, grabbing up his finely made wood-handled umbrella and saying “Angela, I’m leaving now, will you take this down for me?”


  Call the roller of big cigars,

  The muscular one, and bid him whip

  In kitchen cups concupiscent curds. 

  Let the wenches dawdle in such dress

  As they are used to wear, and let the boys

  Bring flowers in last month’s newspapers.

  Let be be finale of seem.

  The only emperor is the emperor of ice-cream…


The Lusty Month of May

psaudiobox.jpgThat’s about all the time I had with it too. Tim O’Connor of Kitsune was understandably coppery keen to keep one of his latest production coppery May DACs in active rotation among reviewers/listeners keen to lay ears upon it; KTE Mays being newer and in relatively short supply these days and all. So I’m gonna tell you straight out this is one of, if not the, best DACs I’ve ever heard. Even during the week or two long continuous play/break-in period in my headphone system, except for perhaps a slight welcoming warmth, nothing stood out except for my own nagging feeling that I was hard pressed to point out a single sonic area in which I’ve heard this DAC bettered.I’ve not heard quite this degree of touch, space, bass and detail on good ol’ ‘Sunday at the Village Vanguard’ on Tidal on other converters. Instrumental separation was fantastic. Did I mention the (wide-open) spaciousness? Oh, I did.”

There are warmer DACs like my previous Burr-Brown 1704 fueled Aqua S2 La Voce or my briefly owned MHDT Orchid with WE tube or the PS Audio DS Jr I recently owned (and sold). There are very detailed DACs like those from Benchmark and Chord (I’ve had the excellent DAC 3 and the less-excellent Hugo here) and all the high-end Sabre rattlers, and there are 30K dacs none of which I have heard except in a friend’s system for a day or so (DCS Rossini). Then there’s my bevy of ‘headphone system’ DACs, like the Sabre-toothed Resonessence Concero HD, Burr-Brown 1796 based Arcam IR DAC with Sbooster LPSU and the Schiit Gungnir Multibit, all of which do different things and stuff and do them well.(And then there’s my reference DAC, the Aqua La Voce S3, but more on that later!)

But as soon as I heard a (somewhat) burned-in May (circa 250-300 hours; Tim of Kitsune recommends 500) connected to either my ALO Studio Six headphone amp or my Monoprice THX 887, I knew this would be a difficult review to write. Flowery prose or none, the May DAC gets so much right even I started to think measurements might matter! Of course, every other DAC I’ve heard in my recent experience also probably measures just as well or better but they aren’t quite at the playback level of the May.I’d have noticed.

In my headphone system, with my iMAC hosting Audirvana and feeding the May via my new fave USB cable the AQ Carbon, the speed, retrieval of detail and general tonal even-handedness this DAC displayed were quite extraordinary. If this DAC wasn’t ‘perfect’ it was very difficult to describe any perceived imperfections. It did not seem to editorialize, over-hype the bass or roll off the extremes. It did not irritate or highlight. It seemed neither particularly clinical nor particularly warm. If you’re looking for something in particular, I’d venture to say you wont find it here; the May doesn’t seem to have much of a ‘flavor.’

mozart9.jpgMozart’s No. 9 piano concerto (‘Jeunehomme’), here played by Mitsuko Uchida with conductor Jeffrey Tate on Philips via Tidal is one of my bellwethers for PRaT and engagement. Since I’ve heard it so many times, if I’m engaged and listening through till the end, something great is happening; and it was. The first movement of this decent-but-not-great recording positively gallops along but not so quickly that I didn’t notice that Uchida’s piano sounded distinctly more ‘bell-like’ than I’ve heard it before and seems to have more overtones than I may have noticed previously. In other words, it’s not as one dimensional and ‘tinny’ as it can be on a lesser converter. Echoes and decay from those top notes pinging in the hall go on and on; a hallmark of great resolution.And you can sort of sense the felt-hitting-string gestalt of the instrument better than with most other DACs in my experience.The second movement, at a more stately pace, underscores the added decay time I’m hearing post hammer-hitting-string.

Lemme say here and now I LOVE this proprietary Titanis USB input! The May’s USB input is absolutely LEGIT and it absolutely held its own with its back-facing brethren. In fact, in both my headphone system and main rig, I actually slightly preferred it to my usual dish of re-clocked and cleaned USB sent to the BNC input via either my Schiit Eitr and Chord Clearway BNC digital cable or my Resonessence Concero HD (used in its capacity as a converter) with same. I even tried my fave PUC 2 Lite with AQ Carbon AES digital cable and preferred the May’s USB input yet again!

The (supposedly) ‘cleaner’ converter-ized signal was in some cases slightly steelier to my ear than the direct feed from my iMac via AQ Carbon USB. I even tried plugging the Schiit Eitr’s power supply into my Puritan Audio PSM 156 AC purifier. Nope; same preference for USB sans Schiit. Yup; Titanis Rex is legit! The best USB input I’ve heard on any DAC in my experience. That includes the one on my Aqua La Voce S3, whose USB input while pretty good, still has me playing around at times with converters and reclockers trying to wring just that bit more sonically from itsBNC or AES schoolmates. No such urges arise with the May. I declare then the USB king is dead! Long live Titanis the 2.0!!

It was after listening to the best rendition of ‘Sunday at the Village Vanguard’ with Mr. Bill Evans I’ve ever had in my headphone rig that a question began to form in my mind; if measurements are so all-fire important why does the KTE May seem to better my other two headphone rig DACs sonically!?These may be DACs priced under a grand, but both no doubt measure near perfectly as there’s an ESS sabre in one and a Burr-Brown in the other. Via my ALO Studio Six headphone tubed amp and Shure SRH1540’s, the similarly flat-measuring and much pricier May immediately shows both a clean pair of heels in that it is more extended both ways up and down than the Arcam and less ‘shiny’/more fulsome tonally than the ‘sabre-ized’ Resonessence HD Concero and this is pretty obvious even on short exposure. It is also more detailed than both. In the ‘big rig’ main system, particularly under the musical minimalist microscope that is my new Lejonklou Boazu integrated amp, such differences would become even more apparent.

Tweekgeek2017.gifThere it showed somewhat cleaner and deeper bass, more engaging speed, more spaciousness, more pronounced instrumental separation, more detail, a blacker background and less ‘irritation’ on irritating recordings and on and on. It flat out sounded a bit ‘bigger’ than the both of them as well. Is it the R2R ‘magic’ on tap here? Whatever it is, like Tom Cruise’s megawatt smile or Garth Brooks’ megawatt appeal, I’m not sure it can be measured. It can definitely be heard though, and fairly readily as DACs go. Yes, my girlfriend heard it too. After I biased her of course; or did I!? Huh? Huh!! 

Certainly, in either my main system or via headphones, this is some of the best string tone I’ve ever heard from a DAC and Leonidas Kavakos playing Beethoven’s violin concerto is exhibit A, your honor. Due to the superb resolution, I felt I could hear the pressure variations; how firmly Kavakos was bowing the strings better than I ever have before. I could also precisely count his breaths Jand this man can breathe. Of note, in my headphone system my Aqua La Voce S3 can approach the May in this regard but only when aided by my Puritan PSM 156 power conditioner. It doesn’t quite get there without it, where the string tone is a touch steelier and less full of overtones. For unknown reasons (great power filtering built in??) I didn’t prefer the May DAC plugged into the Puritan conditioner. There was more clarity but the treble seemed a hair tipped up.

Returning to the May, the heft of the orchestra; the weight and depth of the bowed cellos and basses and attack of the drums was unparalleled. Kavakos’s playing lights up the hall with echoes that go on and on and I’m pretty certain these kind of decays are just not as readily apparent on my other dacs. And the air around the tone; with the May, such things are readily apparent. It isn’t that you can’t hear them with the other dacs; you can. But with the May, they are easy to hear and right there.

He continued breathing (thankfully) through the first movement of the Brahms violin and piano sonata No. 1 in G in duet with Yuja Wang at the piano wherein his brief pizzicato segment almost midway through was among the most delicate and realistic I can recall hearing on my system. So too the May makes the greatness of this recording absolutely stark.


thumbnail-(10).jpgA terrifically musical pairing!


All of the foregoing seems to argue that measurements maybe don’t count for as much as some might think in that most of the dacs I’ve listened to by way of comparison in my life probably measure as well or better than the KTE May. Ah, but I don’t think any of them sound quite as complete and engaging.Am I just a sucker for the two-box thing or the super exquisite coppery keen side-panels and neato buttons? Well—yes, but that doesn’t explain my predilection for the May over others. Or does it? For that matter, my THX 887 headphone amp probably puts my much pricier ALO Studio Six tubed headphone amp to shame in the measurement arena, but guess which one I prefer to listen to?

Turning specifically to the ‘big rig’, now starring the tiny new Lejonklou 24 watt Boazu integrated ‘reference’ amplifier along with the fantastically musical Xavian Perla Esclusiva standmounts it seems to adore (married 3 months now), the KTE May was a digital superstar. Initially, after that good run-in in the headphone system for break-in followed by early listening impressions, I sat in slack-jawed silence throughout Pletnev’s poetic hike among the Beethoven piano sonatas, including chestnuts such as the Moonlight and Hammerklavier etc.

This was among the greatest musical experiences in my current apartment I’ve had. Not since the days of my old better-sounding apartment and the magical Tekton/Wells/La Voce S2 pairing have I had the pleasure of a semblance of an actual grand piano playing in my living room. The Lejonklou integrated is incredibly dynamic and engaging and it now had an elite-level dance partner in the May. Everything was exquisite; tone, presence, dynamics, bass, clarity. This was definitely among the best piano sound I’ve heard in any system I’ve owned in the past 10 or 15 years. And the May was 33 and 1/3rd percent of that!! Let’s give something to Roberto Barletta’s Xavian speakers and Fredrik Lejonklou’s fabulous integrated.


Here’s what you need to know: One night listening to the Holo Audio KTE May playing Lana Del Ray’s ‘Norman Fucking Rockwell’ album through the Lejonklou Boazu integrated and Xavian Perla Esclusiva speakers, I nearly cried. Cried! THIS DOES NOT HAPPEN. I listen to classical music, damn it! I am… ashamed.  Please don’t tell reviewer Bob Neill! He’ll revoke my classical music license! But THIS is what great audio and great music is capable of; bringing a man to the brink of tears with an inferior genre (heh heh) with an artist who isn’t Pavarotti!! I know! I was shocked too!

Aquaman vs. May vs…  Arcam?

So how did my long-ish term reference Aqua La Voce S3 DAC fare against the mighty May?  Both are 5 thousand bucks. Both are NOS R2R. Both are heavy as hell. (Okay, only one is heavy as hell. The other is pretty light actually). In sum the May has a blacker background, more musically relevant detail and has more tonal nuance and refinement.The Aqua countered by doing its usual Aqua thing of staging yuuuuuge and bigly and punching hard in terms of macrodynamics. Bass is a might more fulsome but perhaps less defined than with the May and there is a bit of fine mist between instrumentalists as opposed to the May’s ‘black vacuum of space’. The most relevant point of departure though was tonal nuance. 

The May simply shows more differences between say, two brands of piano or the recorded space of two different concert venues. The Aqua shows more the shiny tone of a violin solo whereas with the May we get tone plus rosin and wood. You can hear variations in the pressure of the bowing better. The tonal palate is on the whole more interesting; more complex. Perhaps the Aqua is a mite too warm tonally to really show all the glint and sparkle up top that the May does? At times with the Xavians; a warm speaker themselves, it seemed as such.

Actually, the DAC I currently have in house most tonally similar to the May is the redoubtable little Arcam irDAC! This award winning little Burr Brown 1796 DAC from like 2013 has been a favorite of mine for some years for headphone listening. Since it has a way with tone itself, on a lark, I decided to connect it up in the main system to see how close it could get to the May, especially when supercharged with a 12V Sbooster Eco power supply and a Wyred 4 sound USB Recovery reclocker.The answer surprised me. 

Whilst falling short of the May in detail and nuance, tonally it was more similar to the May than the much pricier Aqua. The Aqua was perhaps faster and punchier and sounded ‘bigger’ than both, but the lil’ Arcam countered with more nuanced tonality than the Aqua, especially up top; a tonality that put me in mind of the May! That it has great bass and staging for a DAC that can be had used for less than 400 bucks, well, that’s quite a feat! It is certainly helped by the Sbooster lpsu and Recovery reclocker, so those will add a few hundred shekels to the tab. Hmm.. so maybe a cheap Sony receiver that measures perfectly on SHOULD be my new reference amp?!! Thirty years of searching and it was there in Best Buy all along…

The head and the heart

Even if it’s all in my head, I will go ahead and trust myself. I flat out love the Holo Audio KTE May DAC in every way and feel hard-pressed to describe the audiophile that wouldn’t. In fact, if I hadn’t just gone ahead prior to starting this review and placed an order for an even pricier Aqua DAC, I would be all over the May like whatever flowery, buttery, burnt or crispy croissant metaphor there be. 

In sum and substance, the Holo Audio KTE May is exceedingly well-built, well-engineered and solid, offers multiple digital modes to slightly ‘shape’ the sound to your taste (I preferred the seemingly more tonally ‘natural’ NOS mode), has a brilliantly capable USB input which obviates the need for re-clockers and sundry digital boxes, and sounds positively even, engaging, pacey and nuanced with whatever fare you care to feed it.

So Objectivists and Subjectivists alike, raise a glass! Let us drink to the general joy of the entire table! The KTE May is a powerful unifying force for good. Perhaps less globally important than that, (but still pretty friggin’ important), it’s also the most musically complete and satisfying DAC I’ve ever had in my home. I miss it already.
I bid you peace.

  • The new generation of linear compensation technology solves the accuracy errors caused by resistor tolerance, after compensation, reaching a variance of 0.00005% tolerance accuracy.
  • Proprietary anti-jitter technology that provides a full amplitude of anti-jitter without increasing noise floor and other undesirable effects.
  • Based on this new generation of technology May “” can provide a SINAD of >115dB and a dynamic range of >130dB, which represents the performance limit reached by today’s most advanced R2R architecture DAC.
  • Using the ultimate performance of PLL+FIFO technology, provides 0.1Hz Third-Order low-pass ability to inhibit jitter. It also uses a high-performance femtosecond VCXO as the PLL clock source. Under the premise of being almost immune to the front-end jitter, it can also lock up to 1.5us-2us @ 1KHz signal with high jitter. (It can lock up to 1.5us-2us @ 1kHz signal with high jitter on the premise of almost being immune front-end jitter).
  • Dual Mono DAC L/R channels are independently powered by their own dedicated transformer in the PSU chassis. This provides better channel separation and more accurate sound stage.
  • Official Support USB and I2S up to DSD1024 and PCM1.536MHz sample rate.
  • The USB interface uses proprietary firmware with ultra-low latency, a highly reliable data transmission, ideal USB eye pattern measurements that contributes to 2-4 times higher performance than official firmware.
  • Two sets of independent HDMI-I2S input interfaces are provided, and each set of I2S has a four-way
    independent circuit, as opposed to standard LVDS chip, making I2S clock signals subject to lower
    interference and lower jitter. In addition, each group of I2S inputs can be configured with specific pinout configuration, making it compatible with most of the HDMI-I2S digital devices on the market.
