Yes. I think the key thing is trying to get better sound than 16/44 with the same or lower bitrate, and they might have done that.
MQA•Foolish New Algorithm? Vote!
Vote please. Simply yes or no. Let’s get a handle on our collective thinking.
The discussions are getting nauseating. Intelligent(?) People are claiming that they can remove part of the music (digits), encode the result for transport over the net, then decode (reassemble) the digits remaining after transportation (reduced bits-only the unnecessary ones removed) to provide “Better” sound than the original recording.
If you feel this is truly about “better sound” - vote Yes.
If you feel this is just another effort by those involved to make money by helping the music industry milk it’s collection of music - vote no.
Lets know what we ‘goners’ think.
P.S. imho The “bandwidth” problem this is supposed to ‘help’ with will soon be nonexistent. Then this “process” will be a ‘solution’ to a non existing problem. I think it is truly a tempest in a teacup which a desperate industry would like to milk for all its worth, and forget once they can find a new way to dress the Emporer. Just my .02

I have Tidal and Gen1 and Gen2 Bluesound Nodes. MQA is like a free bonus to me. I haven’t done any critical testing but I listen to the MQA version when available through the analog outputs and use Pure Direct and it sounds good to me. I have quite a few DVD-A and SACD discs and thouroghly enjoy them as well. (5.1 surround is quite enjoyable at times) Now, if I could just find time to unpack the Revels and get them in the mix would be great. Enjoy Chris |
Summary so far (after listening to everything with my own ears) :- 1. Foolish new algorithm? - I vote Yes 2. MQA for better sound? - I vote No 3. MQA for music industry to milk more money? - I vote Yes 4. MQA enjoyable? - Many vote Yes as indeed it is anyone’s prerogative to enjoy any format that is enjoyable 5. Is MQA Tidal better than non-MQA Tidal? - I vote Yes 6. Is MQA better than non-MQA native hires PCM and DSD? - I vote No. Enjoy the music! J. :) |
@roberjerman. Have you actually listened to MQA files or are your arguments purely based on reading tech info? 2 years ago I would have said you were nuts if you thought changing a fuse and even the directionality of said fuse would have ANY sq impact. This i was gladly proved wrong over and a believer was made. The same holds true with MQA, I have read the blurb but I know also what I hear and at the end of the day that is truly all that matters to me in,my system. |

After having downloaded the new Aurender Conductor App along with an MQA license earlier today (first unfold only) into my N100H and then reading the above challenges to compare the sound quality of the MQA files via Tidal to a bonified 24/96 “hirez” file, I realized that I had such a HDTracks 24/96 download of Diana Krall’s “Stepping Out” album (2016 remaster) and the same album and remaster is available on Tidal Masters (MQA). So I decided to compare my two favorite tracks from that album,”Body and Soul” and “Jimmie”, between the 24/96 version stored on my N100H’s hard drive and the Tidal MQA version streamed through the same unit. DAC used is Denafrips Terminator, so same music server, USB cable, and DAC for each version (also the same rest of the system), so this is about as perfect an “apples-to-apples” comparison as can be staged. After several rounds of swapping back and forth, I am confident that the differences is sound quality are absolutely minimal. Perhaps the 26/96 download was a touch more resolved than the MQA version but not enough to be able to select one from the other consistently, nor to alter the enjoyment of the music in any significant way. Two other things that I feel confident in laying to rest: 1) the MQA update is not affecting the sound quality of the downloaded files in my N100H’s hard drive (I listen to both of these tracks from the 24/96 download multiple times as evaluation tracks when comparing components so I am intimately familiar with them) and, 2) both the 24/96 and the MQA version sound so much better than the non-MQA “Redbook” version on Tidal that even the most hearing deficient among us would have no difficultly hearing the superiority of the MQA version over the Redbook. I have close friends that are very strongly polarized about MQA, both pro and con, as to its potential impact on the music industry and component manufacturers, etc., but personally I don’t give a flip about anything but sound quality and I am satisfied that MQA is a blessing to those of us that are heavy Tidal users and value best possible sound quality.

@jon2020 “So you are comparing MQA 96 to non-MQA 44.1? A more valid comparison would be between MQA 96 and non-MQA 96 PCM.” Why? I’m looking for an improvement over cd quality streaming. I agree that MQA may not be the equal of high resolution downloads (I don’t know for sure, I have not compared) but why is a comparison with non MQA 44.1 not as valid if my objective is to receive better than cd quality sound? My comparisons have been my cd collection saved to hard drive vs. same titles on Tidal with MQA processing. MQA sounds better on my system (PS Audio Directstream jr). If my PS Audio is now doing something to 44.1 files that make them not sound as good pre MQA then yes I want to know that. “However, I would hazard a guess that maybe, after paying for the MQA download, one would prefer not to investigate further just in case the new findings invalidate the purchase.” That is certainly true with many things audio but not really relevent to Tidal users. You pay your 20 bucks a month and you get cd quality streaming, oh and by the way you get a bunch of MQA titles as well. Happy listening. |
@jon2020, I don’t feel the need to further investigate or loose my sleep over $54.99 MQA Core Decoder upgrade. To my ears, most MQA coded files easily yield audible improvements in my system over Tidal 16bit/44.1kHz files. And to answer your earlier question about why not compare MQA 96 vs non-MQA 96 PCM coded files is pretty simple...why pay for 96 PCM files when I can enjoy just as good MQA 96 files at no additional charge. As you said, “It is never necessary to compare what you are enjoying with anything else :)” |
So far I have found MQA played via Tidal through my Vault 2 "sounds" more refined and solid than non mqa version. It doesn't really matter when you have an MQA dac as you can't really compare unless you have another non-MQA dac side by side. Anyway, we should always enjoy music that is enjoyable. It is never necessary to compare what you are enjoying with anything else :) |
So far I have found MQA played via Tidal through my Vault 2 "sounds" more refined and solid than non mqa version. I have read the technical blurb I cannot explain why in my system it sounds better....no more so than why I can explain a change in a simple fuse sounds better either. At this juncture I do NOT CARE! I will continue to play what sounds better to my ears on my system Thank you |
"I can clearly discern the audible differences between MQA coded file at 96kHz and it’s 44.1kHz counterpart file by enabling and disabling MQA Core decoder. " It always makes me wonder why any hobbyist in audio would want to bury their ears in the sand with respect to valid comparisons. The lack of curiosity is hard to comprehend. However, I would hazard a guess that maybe, after paying for the MQA download, one would prefer not to investigate further just in case the new findings invalidate the purchase. |
@lalitk, Stereophile were pro MQA, until recently when they started doing measurements, now they'er sitting on the fence a bit. They could have blown the $5.5K Aurender A10 thing wide open, they even asking Aurender to comment on this sly slip of the hand, but they refused to reply to what Stereophile found. I praised JA for telling it publicly, even if it was on the quiet. Cheers George |
MQA recommends "Upsample Always" for non-MQA files.....Wow! https://www.computeraudiophile.com/forums/topic/30381-mqa-is-vaporware/?page=279&tab=comments#co... |
lalitk How do you know, all the filtering has been switched off when not in MQA but PCM 44.1?? (you think it is) Have you got Stereophiles measuring equipment? As this is what it’s all about!! Cheers George |
"In the $5.5K Aurender A10, MQA did switched off, but part of the MQA’s filtering remained active in the Stereophile tests when measuring/playing non MQA files, and no different firmwares fixed the problem. The filters that remained hobbled the non MQA sound for the worse. One must ask the question, is this done on purpose? to make MQA look/sound good compared to non MQA?" +1, georgehifi. This is exactly what I am afraid of. |
lalitk876 postsYes, it can be disabled.

Before anyone downloads the Aurender MQA software, you may like to consider whether you can switch in and out of the decoder at will to allow for comparison. At the moment, I don’t yet see that option. I can’tell be sure if "Enable MQA unfolding" is a pure switch in and out once the software is downloaded. This issue would be moot for MQA dac owners. I have brought home a full MQA Meridian 808v6 player in the past for a home audition and comparing an MQA file played through it with a non-MQA version played through my Esoteric non-MQA dac, I found that the MQA file sounded softer and darker overall with significant blunting of transients. |
george, point taken. My very simple comparison method was streaming both MQA and non-MQA versions of the same album from Tidal through my Bluesound Node2. Not very scientific but the best I could do. Whatever they do, the music just sounds a little more detailed. Not saying night and day but incrementally better to my ears. I do however agree this thread is a bit useless in terms of content (and context). |
THIS IS BS!!!! STOP ALL VOTING!! THIS THREAD SHOULD BE SHUT DOWN AND RESTARTED PROPERLY, AS IT COULD DO MORE HARM THAN GOOD. AS THE TITLE OF THE THREAD IS IN DIRECT OPPOSITION TO THE "YES" "NO" VOTING CRITERIA IN THE POST, DEPENDING HOW ONE READS IT kalali1,033 posts03-06-2018 12:27amAll I can say is an MQA version of an album sounds better than a non-MQA version of the same album. Same system same volume.Be very careful how you conduct MQA vs Non MQA A/B’s on the same unit, as it was found that on the new $5.5K Aurender, that some of the MQA filtering was still on, and "hobbled" non MQA albums. This was still the case even after getting numerous new firmware’s to fix it. https://www.stereophile.com/content/aurender-a10-network-music-playerserver Cheers George |
Have not heard and compared, but it is a lossy compressed format which by definition means less accurate than original. So that alone seems like a step in the opposite direction in regards to at least the accuracy of the sound. Of course the most accurate sound does not necessarily mean "best sounding" so there are lots of other digital processing tricks that might be played to make things sound better, even with less accurate data to start. It sounds like the highest frequencies are being transformed in a lossy manner in this case. So trained younger ears might be better equipped to distinguish than older, if audible at all. Kinda like a Trojan Horse perhaps in practice. Most will probably never notice a difference even if there is one. |
This just in....Aurender N10/N100/W20 owners now able to purchase MQA Core Decoder license from within the Aurender Conductor app for $54.99. This will allow users to hear MQA coded files at 88.2kHz or 96kHz sample rate through a non-MQA compatiable DAC’s. http://www.aurender.com/blog/new-software-release-note-4/post/system-sw-4-5-11-36-app-2-9-3-93-189 |
Ptss - When I read your questions it sounds like your asking about the "intent" of the format, not whether it sounds better or not. So to answer what I read as the intent of your questions: Yes, I do think MQA is a processing algorithm that was created for better sound quality, and Yes, it was created to make money. What isn't done to make money? Let me know if I'm off base with my understanding of the question. Now, do I think MQA makes an audible and worthwhile difference versus redbook? With my system and the music I listen to 100% yes! Is MQA inferior to high resolution downloads, SACD and vinyl? Maybe, I don't have the ability for direct comparison. But listening to MQA on Tidal allows for better than CD sound (in my system) and the opportunity to listen to a vast library without having to purchase each download, and accessing those choices is darn near instantaneous. If I were into those other formats I would explore the world on Tidal then buy what I like on high res DL, SACD or vinyl (if available). I don't see this being an either/or proposition. I realize this isn't a debate on the pros and cons of Tidal but it sort of goes hand in hand with why you would want MQA processing. So there is a market for MQA processing and I guess it's for folks like me. Oh and did I mention it sounds better than CD? Sorry, this is Audiogon. No such thing as a yes or no answer ; ) |
Yes, 100%. For me, it’s a no brainer. In my system, MQA sounds great, so I will continue to play it, and continue to enjoy the hell out of it. If you have a subscription to Tidal, like a lot of us Agoner do..it is simply a gift. Temporary, maybe? In the meantime, I’m going sit back, relax, and keep hitting play! |
