@craft-o-matic399 replies to @AudioMasterclass: I have to be honest dear sir. I didn't care for the sound of any of these DAC units. However, if I had to choose one, I would reluctantly choose DAC X.
Really enjoying your channel! I will subscribe as soon as I finish this comment. Thank you!

@leosgolf replies to @AudioMasterclass: I listened on a simple macbook air M4 and I thought A & X were the same. The most defining feature for me was a more holographic effect in the clips with the electric guitar section ... the sound simply had exta depth and width to beside me instead of just coming from the macbook ..maybe distortion that I liked more as well.
@terryprater8115: From Wikipedia: "An audiophile is a person who is enthusiastic about high-fidelity sound reproduction. An audiophile seeks to achieve high sound quality in the audio reproduction of recorded music, typically in a quiet listening space in a room with good acoustics." By this definition, we are all "audiophiles". I'm tired of hearing this term tossed around as if it were something sacred and unobtainable to most of us.
@terryprater8115: I'm very surprised that you would make a video about comparing two DACs. Just one year ago, you claimed in another video that you couldn't hear any difference between using a DAC and not using one. What changed your mind?
@g-mail4743: I soldered the internal wiring on my Polk R200's DAC A = DAC X , DAC B is so rich
@petermartin9494: Ok, what dac is A and and which is dac B?
@tortordenful: If you had been "clever" you could have switched dac's between dac-x segments and really given us a test 😂
@kappa408: Dac A
@wayneromanowicz8525: Listening to these dac's side by side would take a bit of thought to decifer quality. I believe preference might come in over a period of time listening through a competent system to which one you would prefer. That opinion could be translated into a level of ear fatigue or comfort level as you go forward with a choice. Any which way the final judgement doesn't jump out at you per say, unless told/revealed the identity ahead of time, your not placing a heavy bet on a sure thing with what you hear.
I purchased a Sony Progressive scan CD player in the very early 2000's and use this through my Yamaha RN-600. Although the 600 has a Sabre 32 bit dac compared to the Sony's 24 bit I find the quality of sound good, so much so I haven't wired the Sony yet to by pass it's 24 bit signal. However, I do notice a bump up in quality of sound when streaming directly through Yamaha's 32 bit, it's cleaner more natural sound appears slightly better than the Sony's cd play. Does it equate to $1000 difference...........no. The science of splitting hairs remains to be seen, I'll leave it to the experts.
@ThinkingBetter: A DAC is seriously poorly designed if this is the way you can hear it sounding different on a YouTube video. A DAC can nowadays quite precisely track the analog output against intended digitally stored audio waves and should not be questionable in other than the highest treble when LP filtering Red Book 44.1kHz 16 bits music. But unless you are in your teens or early 20s, you are unlikely to also hear such difference...yet again, assuming the engineers designing the DAC know what they are doing. Same goes for jitter. There is no audible jitter if the DAC is properly designed. Any DAC needing external re-clockers and special USB cables to become sonically transparent have some serious design flaw. Throw out such DAC.
@drbarney1000: The R2R ladder DACs were considered the best there is, but they rely on precise resister values to sound good. But as years pass, resistors change their value and lose some precision. A high-cost audio component must last for years without degradation before I want it. Newer DAC chips have much higher resolution than is possible through an R2R. They are less costly.
@gj8550: Trying to hear the difference between 2 DACs on a YouTube Video that you are watching on a phone or tablet is borderline absurdity. If Youtbe hasn't filtered out the nuances, your playback devices would certainly masked a good portion.
@tailwagga7701: More body to DAC B
@donmason356: dac X is dac A in my blown out ears.
@santanubhattacharya9102: My thoughts: DAC X is the Duke thingy.
I am not an audiophile under any circumstances, heck cannot afford being one. But I could hear, may be incorrectly, some subtle difference between the cymbal crashing between DAC A and B. And X corresponded more towards DAC B, which apparently is the Duke
@patbarr1351: Cute! An "analogue internet" wouldn't be helpful at all. There would still be miles of transistors, amplifiers & transformers in the signal path. Why not an "acoustic internet" with CNC machined tin cans connected by audiophile-grade string?
@twentyeight00000: I listened on my iphone 16 plus, jbl in-ear headphones and there is not much difference, I think I cant hear the difference 🤷♂️
@OrazCostanzo: Unless your superhuman or a cat you cant hear a difference
@Anyoldtime48: No brainer for me based on very limited budget. Listening via my 2012 Audioengine D1 (24 bit) to work past the internal Apple card....and new HD 599s after my HD 595's gave up the ghost on the right channel. Would have liked better headphones, but got what works for my budget. Similar specs to the 595's, and circumaural open back. Still forced to use an adapter from 6.35 to 3.5mm (on the Audioengine) and the Douk will provide me with the larger headphone plug input. Plus the RCA outputs on the back which I might find use for at some point. Thanks much for the video!!
@wreckingopossum: Either DAC X = DAC A, or I have gone crazy. DAC B is noticeably better. When you started playing DAC X I thought I had accidentally gone backwards in the video.
I watched the video on a OnePlus 10T, wired, USB-C to USB-C to powered on Shure Aonic50 Gen 1 headphones with Bluetooth disabled on the phone
@MarkJSage: For whatever reason dac B seemed to have just a bit more richness or fullness. But I don't think I could justify spending that much money for the other one for such a small return.
@Gouemu: Since I don't really speak English, I just listened to the sound test using my FiiO FT1 headphones and let AI handle the rest by pasting both the test and reveal video links.
I guessed DAC X was A, and that B was the pricier model because it sounded clearer and had a stronger attack. Turns out my ears were right on the mark.
It was a lot of fun!
@Urizen61: I have to admit I can't hear a difference. I like buying stuff that is well-built, stuff that is going to last. But I can't tell the difference between the two. Would I be able to tell the difference if I was in the room? It's possible, but I'm skeptical.
@vendelius: I heard a nice difference .. alhthough the cheaper dac was still adaquate
@vendelius: I didn't know Ifi has such expensive products.. Fun video... Thanks
@jones5311: DACX sounded like DAC A to my ear. Im no audiophile, I’m still trying to decide the type of sound I like.
@jacquesw8725: Oh yeah let's listen through youtube to get great sound to compare A to B! Unreal the idiocy here!
@AudioMasterclass replies to @jacquesw8725: Hahahaha. The whole world now knows that you’re the idiot. IDIOT haha. Hahahahaha.
@AudioMasterclass replies to @jacquesw8725: Replying to my own comment for the benefit of comment readers, this commenter failed to observe that the description box of the video has links to WAV downloads, so YouTube audio is irrelevant. I announced this clearly at https://youtu.be/h_fw6QFE4tQ?t=314 before the test. Of course there are still limitations to this test even with downloads, and I comment on these in detail at https://youtu.be/h_fw6QFE4tQ?t=98 I suppose I should apologise to the commenter for being a bit harsh, but I can't be bothered.
@jacquesw8725 replies to @jacquesw8725: @AudioMasterclass AWE baby got his feelings hurt? LOL I know the truth does hurt sometimes! And btw, you have had close to 50K views on this video. How many of those viewers do you think have a system that can reveal the differences? And frankly this is all subjective even with great components! Who's the dummy now? hahahahahahahahahahaha
@CareyMoulton: DAC X is the Douk,
@aderau-t5c: DAC B and DAC X sound slightly better than DAC A. But the price ratio is crazy 16:1
@peterhuynh6640: Dac B sounds better. Dac X is B
@charlesromney: I think DAC x = cheapest one.
@maeitea-ti2fh: Oh what the heck. You can clearly hear the difference, even without downloading files
Fullness of DAC-B. On DAC-A you can hear distortions on first seconds.
I would never go for DAC-A.
@Mister_Shane: I’m not familiar with either DAC, so I don’t know which is which. What I hear is that I can’t stand the overly crispy, crunchy highs in DAC A. DAC B has smooth highs but excessive mid bass. DAC A reminds me of a cheap ESS. DAC B reminds me of 90s PCM56A Burr Brown Sony CD players.
@gammaraider: I've fiddled around with different DAC's too here at home. Even in a direct A-B test I can't hear any difference, which is exactly as it should be, unless your DAC is deliberately colouring your music. Thanks for telling it like it is.
@_enex5505: I've watched the whole thing and ignored both models of the DACs and which one is the better one. All I can say is, to my ears, B sounded better and X was B. Am I correct? No clue yet
@_enex5505 replies to @_enex5505: In my defense to this response in particular, I've listened to this audio through YouTube. I've decided to compare audio A with audio X and both sound different (again, on YouTube). Not only that, after AB testing both audios (just with the drums) I can differenciate which one is the audio A and which one is the audio X. HUH?
@ltdrd2024speed: 2 is x
it's obvious
@xray111xxx: It is what you heard. No wrong answers. Unlike the Audiophile cognoscenti would have believe how wrong you are. Stop sweating it, and love the music, and put the analysis away. Life is too short.
@arturogonzalez-arquieta7882: To me, DAC X is the first one. I do hear a difference. Big difference,
@asterixx6878: DAC A is the better of the two. It's more open and crisp.
@ruderabbit797: we, watching from a monitor or TV will not even know the dif, so yea, a fun showing. Loved the Passive Aggressiveness of this. 🤣 I felt the Valkyrie was B and X. Though liked the mellow tones of A. I'm a strong, yet mellow mid listener.
@WeThrowPie: I'm pretty sure those glasses are for trans people or something.
@claptrap22: I find those that say they can't hear a difference interesting. The Douk sounds quite fine, but it definitely sounds smaller and more compressed than the iFi, by comparison. The ring on the snare hits is more apparent and rich on the iFi and cymbals shimmer more, fore example
@virgogreg: A reverse phase summing test would be interesting
@AudioMasterclass replies to @virgogreg: It would indeed be interesting but clock drift makes it impossible. I did come across a software that claims to correct this drift but I doubt if my ancient Windows laptop would be up to it. In any case I'd have to wonder whether it would cause more problems than it solves. I'll keep an open mind and if I find a solution I'll try a test.
@hagbard72: B but I could live with A, especially given the prices.
@RetroVHSFest: Listening to files with the YouTube compression is pretty funny
@AudioMasterclass replies to @RetroVHSFest: What's really funny is the number of people who complain about YouTube audio despite me saying exactly this... https://youtu.be/h_fw6QFE4tQ?t=314
@apolloxiii5574: I don't hear any difference, the YouTube compression algorithm and my computer DAC makes everything sound the same, maybe the original soundtracks makes a difference.
@bikeman123: So we are listening to a analogue recording that has been converted to digital and then is played through a dac to convert back to analogue, which is then recorded as an analogue signal and converted to digital then uploaded to youtube who compress it and then we convert it back to analogue on whatever device we use to listen to it. 😂
@SuperDeepfield: X=A=iFi
@andrewstafford-jones4291: I have 4 differnt DAC's at price points up to 3K.
The presentation of all the DAC's is all completely different and the most expensive one is simply in a different class to the others.
Speakers are SCM100ASL (Active) in the latest specification.
@voiceofreason9238: I haven't read any comments. DAC X is the same as DAC A and I determined that SOLELY from listening to the sibilant "s" from the female vocal and comparing . I heard sibilance from DAC B. I'm not sure about this next thing, but I think I liked the piano better on DAC B, the difference is so subtle.
@_TheRealGod: I was hoping for DAC Donald!
@bradtowne2305: Listening to two different DAC's, through the cheap DAC on my laptop is clearly, the way to tell the difference.
@whizzkidd4: I like b
@raypena1516: they all sound good. hard to say which one I like the most.
@michaelgahan2968: I must be blessed bc my DAC on my iPhone streaming to my system with Bluetooth receiver sounds just as good
@chahyadirusli5219: Dac X
@Farhan-xu6rr: Dac B wins, more body, more space between instuments, voice is better and more real, less hursh, i can hear the ambient, enjoyable. The X was Dac A. It's more flat. I didn't even play with my setup. I downloaded and listen from my phone using airpod pro. Hope I'm right
@duaneselby6743: I'm going to say X was Dac A. The music just lacked depth and body; it just felt thin and flat. On Dac B, the music had more depth, was warmer, fuller, and more detailed. Im listening on my Hegel 120 and Focal Stellias.
@bogdanniculescu4941: B the best
@عبدالسلاماحمدعبدالكريم-ص3ك6ج: لا تنفع افضل الاجهزة اذا العيب في التسجيلات في اختلاف بين استدويات التسجيل وكذلك علم مهندس التسجيلات وكذلك كذب الشركات تكذب وتغش
@andreasrochow5170: Once again, I was able to see just how well my DAC and stereo amp work together with the Quadral “Amun X” floorstanding speakers. My favorites in the test were the DAC A and DAC X. May I ask why you don't carry any acoustic bass models in your lineup?
@mariusandvickipessah6535: I have noticed that almost every week there is a new DAC reviewed on YouTube which the reviewer claiming that it’s a huge breakthrough or a game changer . Many times it’s the same company with a minor tweak with a concomitant change in the model number and increased price . Yet there has been almost no mention of Schiit DACs at fraction of the price . The adjectives used to compare the DACS are reminiscent of a menu at an expensive restaurant . I advise checking your amplifier and speaker ohms to make sure you have enough power . Position your speakers properly or invest in a good preamp that would improve the sound of your system better than the DAC and don’t forget decent cables . Great review !!! I agree that the sound of DACS don’t make that much of a difference . I’ve owned a Schiit Yggy for years and I’m in heaven .
@donk1822: I can hear the differences between my Audiolab's various filter options quite easily, I always end up on the optimal transient whenever I've scrolled through them blind, but I can't hear any difference between them, DAC X could be either to my ears.
@NickPuentes: Ultimately, the difference is very subtle, but I think DAC X sounds like DAC A.
@jacquesmertens3369: I have partial hearing loss and I can no longer hear very low or high frequencies. But I think X = A = neutral, dry and B = slightly warmer with a bit of added resonance.
Therefore I assume A (and also X) is the cheaper one, B is the expensive one.
@gianlucabassi8853: My vote for A
@archiemadison764: DAC A sounds more lifelike
@paulstubbs7678: There WAS an analogue 'internet', it was the old analogue phone network - however unsuitable for this use.
I think 'X' was the Douk K5
As for the inversion, it's got to be the internal design of the K5, as lead wise the only one that can do that is a miss wired balanced lead, that I don't think you were using. I used to think this does not matter - as long as both channels match, however I've seen some banter of late on YT telling of the horrors of signal inversion.
In one of my setups I have a cheap plastic combo DAC/ADC where I played with its USB feed (that is also it's power) running it through a filter and a linear 5V power injector - It now sounds WAY better. to the point I am no longer looking to replace it.
Darn, I just noticed this video is 8 months old - Yikes I hate it when YT does that to me.
@jonathanstarr3568: Thank you for this test. Financially speaking, I could only ever afford the first one to begin with and now I will not regret my decision.
@bobc3997: What a ridiculous idea. We're listening to it streamed by low-fidelity YouTube.
@AudioMasterclass replies to @bobc3997: You’re an idiot. I’ll let you figure out why.
@philipw7058: The comparison is infantile and shows no understanding of audio,the more revealing a system is,and if the room has treatments or not, witch will make the room more revealing,that is the criteria for hearing difference’s in audio electronic sound difference’s,this need to compare audio devices is ridiculous,it comes down to topology that the designer implements in his design, all Dacs are not designed equally that’s what makes this video childish and was a waste of my time
@AudioMasterclass replies to @philipw7058: Haha, the classic audiophile snob’s riposte. “Your system is insufficiently resolving therefore anything you say is meaningless”. “Anything I say however is true to the utmost degree, even if I offer no evidence to prove it.” Thank you for the entertainment. I had a good laugh.
@philipw7058 replies to @philipw7058: @AudioMasterclasslike I said childishly answered,the only thing ignorant people can do when they don’t understand anything is to laugh,I guess you think all audio electronics sound the same ,people like you are a joke and I’m the one that got a good laugh and won’t waste my time watching any of your ignorance,go get a better system or get your hearing checked
@alexbucher5179: What comes on top is that hearing a difference doesn't even necessarily help you on your decision. The difference can be positive with certain audio material and negative with another one. As to say there is no loudspeaker or room, DAC, Amp or even an instrument that is universally better in everything. Just different.
@Jarrettfan: I couldnt hear any difference on my phone at all.
@doncampbell1961: I could not tell a difference. I was running through a good dacs on my 7700x motherboard to my amp and eq set up through polk audio speakers. Only thing i can tell you is they were all glorious recordings. funny I enjoyed them more than I should have , lol.
@iSot80: I can hear the difference between these. The easiest to see the difference is to listen the woman vocals.
@MrJohnAW: Sorry if I am rather late to the party. Very hard to tell on my kit, but maybe X is the Valkyrie?
@WispGlitch: I didn't even need to download the .wav files to hear the difference very clearly.
Youtube audio didn't have an impact on the ability to hear the difference.
The difference between the two dacs was clear.
Dac A had higher distortion overall, and had higher peaking on the highs.
Dac B had less distortion of sound overall, but especially handled the higher tones way more effectively.
This gave it a bit more of a clearer sound and made the sound hit your ears a bit "softer" causing less ear-fatigue.
All of the samples together did allow for a better clarification of this, and the MOMENT that track X started playing, I instantly knew that Dac X is infact, Dac A (The Douke).
I then played the samples of both dacs again, only this time I took the same segments and played one, then the other.
This once again verified what I was hearing.
Just having quality headphones is enough to hear the difference.
@dabirdcageofdoom: Sitting in a restaurant using my phone, on mute, I could still easily feel the difference in aura, emanating from the music. Chocolate versus plain vanilla.
I need to get my phone cryo treated. That would be amazing, I bet.
@joeMW284: Should just do a null test and call it a day.
@wapphigh5250: The "other" British Audiophile needs to watch this...
@AudioMasterclass replies to @wapphigh5250: I’ve watched some of his videos. Apparently his wife has very acute hearing. I’m divorced.
@raju365: DAC A is more open and airy, but slightly artificial. DAC B is more closed-in, yet more natural and realistic. DAC X leans toward DAC A’s presentation. This observation is based on listening through my phone speakers on YouTube.
@JohanDee: € 89 is not cheap, try the SMSL SU1, way cheaper... But what about the built in DAC?
@patthewoodboy: if you cant tell the difference , then the expensive DAC had the same cheap audio output
@tubecollector100: i am sorry to say this . i am very suprised that all the music in the test seems to be so low in quality . there is a lot of music uploaded to youtube that sounds a lot better , i really would like to know how this is possible.
@AudioMasterclass replies to @tubecollector100: I don't think that you're sorry at all. I think that you didn't listen to what I said before commenting. Have a shit day.
@tubecollector100 replies to @tubecollector100: @AudioMasterclass my day just got a lot better :) i already suspected that you would not try to upgrade the content of your channel... and do not like to value honest opinion. i do wish you a very nice and sunny day , and your followers much wisdom..
@kevinbentley3790: At first I thought the cheap DAC (A) sounded better and X was the same as the more expensive DAC (B). I heard some warbling (for want of a better word) on B and X. Then I realized I was listening at 1.25 speed. Listening again at normal speed I couldn't tell any difference between the two DACs. Both sound clear and detailed. Personally, I'd 'settle' for the cheap DAC. Will refer to the results on the follow up video now.
@AudioMasterclass replies to @kevinbentley3790: Now everyone will want a warbling DAC.
@kevinbentley3790 replies to @kevinbentley3790: @AudioMasterclass True. Makes me wonder if could obtain crowd funding for a new Hifi company to be named Kazoo Audio.
@jhon33761: A=X . Sounds better in my ears then B. Hope it's the cheap one, cause cheap is all I can afford.
@johnthornton3863: Enjoyed video. However the cynics who say DACs and Amps sound the same, apparently think only speakers are different. Maybe you deny even speakers. You are very wrong. 🔊
@user-if3gv7pt7n: The same audio tracks are so much timewise apart I can't hear a difference ( I can't remember what it was sounding like before)
@1112-LXH: Dac X is Dac A. To me, Dac A is more lively, soundstage and clearly.
@thatguythatdoesstuff7448: I think DAC X is DAC A. And honestly, I liked the drums on DAC A better, but everything else I liked better on DAC B.
@carl-ludwigcombler4088: Listened on the built-in speakers on my MacBook. I think A = X. I like the sound of B the best personally. It sounds more airy to me, especially in the drum part.
@you2ber252: Through youtube the difference is subtle, due to there being a lossy codec in the chain. Even listening to the wav files would not be ideal, since there would be a third DAC in place (the one used to reproduce the files). However even through youtube, to my ears DAC X is DAC A (the cheaper one). As far as my own DACS are concerned, I can definitely tell which one is which by listening to them. The differenece is pretty obvious. I am not a dumb "audiophie", I am a technician. Nevertheless, the difference is pretty clear.
@philmccracken2012: Any kind of mouth sounds always gross me out! When is a microphone obviously right next to somebody's mouth and then you can hear them smacking or whatever you wanna call it. I could never understand ASMR mouth sounds!?
@paulboyce8537: Douk K5 is X. Why? The sound on vocals and acoustic guitar was almost as clear but lacking stage presence further away. Drums and piano sounded very muddy compared.
@jdl8350: I felt Dac X is DAC A which is IFI, and DAC B is the Duke I guess, but I can‘t tell big differences.
@kokopellie: Thanks a lot for all the effort that must have gone into this!
I downloaded the files and imported them into Garage Band to make it easier to compare them. I’m listening to the samples on my Beyerdynamic DT 1990 Pro headphones through my Schiit Jotunheim 3 DAC/Amp with a mesh card.
I must say that my DAC seems to be doing a great job and appears to be on par with the Douk or Valkyrie when playing the original WAV file. However, there isn’t enough difference (to my 71-year-old ears) to justify the over $500 price difference between the two.
@archiemacdonald553: Cheap dacs expensive dacs its how the whole design is put together buy the manufacturer cheap dacs can sound much better than expensive ones its all about its implemented . I could be wrong but anyway 😂
@hipoint4599: Two words Expectation bias
@Scan_Speak: I bought a well made bit perfect streaming DAC that sounds great. Unless it outdates in features I require or malfunctions, I’m not replacing.
@dougcarmack5426: I don't understand what you are doing.
@dougcarmack5426: How is it regulated between A,B,X? Three dacs or two. If two how?
