MQA is not audiophile to me but snake oil or may be even worse. What hardware and music did you use to come to this conclusion about MQA? MikeyFresh 1 Link to comment

But for your sake I copied and showed it to you below. However, I do not believe my current audio system make me arrived at the conclusion cos' I have changed gears along these years since MQA surfaced in the market. It is the source that matters. Stereo: NAS & MSB Premier Dac (Isotek EVO3 Acension PC) --> Crystal Future Dream XLR --> Soulution 525 (Crystal Future Dream PC) --> Crystal Future Dream XLR --> Soulution 311 (Isotek EVO3 Acension PC) --> Crystal Kondo Operia SPs 2.7--> Audio Physic Midex AV: OPPO 203 / Pioneer LX500 --> Pioneer LX-901--> ELAC CC 241.3, KEF LS-50, KEF R-50, JL 110 Power Conditioner for Stereo: Isotek EVO3 Mosaic Genesis & Isotek EVO3 Genesis One Power Conditioner for AV: Isotek EVO3 Sigmas The MSB Premier supports MQA through the renderer module and it obviously has the resolution to expose hi-res recordings. This systems seems like it should have no problem with revealing MQA qualities (or lack thereof) unless you didn't have a MQA DAC at the time. Can you think of some albums that you were unimpressed with that made you discard MQA? Link to comment

But, it was of the same calibre. I played versions of music I knew both non-MQA and MQA versions. Except for being louder, all the MQA versions sounded like shit. Example on a Melody Gardot piece from " The Absence' - So Long (both were supposedly 96/24 versions) The guitar on the MQA version sounded like a plastic stringed guitar, not full like the others. Her voice also was very thin. That was enough for me. It sounds likely if you don't recall the front end it wasn't MQA capable. However you did note a change that was memorable so maybe it was MQA capable. I'll review this track and see if I can hear this degradation of quality. I haven't come across a degradation with MQA, it's always either an improvement or no difference at all. Link to comment

Just a small handful of people in Japan have any of these, so that's quite a short list. Just an album but with an MQA version available. MQA-CD is actually a combination of MQA and UHQCD which is a new disc media material and mastering process. The discs return a stronger signal to the reader. I also tested these independently (ie, UHQCD with no MQA) using samplers from JapanCD. The samplers contain a UHQCD disc and a regular CD of the same tracks so you can compare them. When I tested it with my older DAC and CD player, I found there was a minor improvement in bass definition. Actually I should go back to them using my new DAC and CD transport. Aside from MQA-CD, you can buy MQA downloads from certain sites. The one with the largest selection as far as I know is Highresaudio.com. Link to comment
Popular Post GUTB Posted December 31, 2020 Author Popular Post Share Posted December 31, 2020 Last month I received a CD transport from AliExpress which claimed to copy a Wadia circuit. It was close to $1k after shipping. I ended up breaking it trying to open the case but luckily the seller was willing to ship me a replacement cable harness for the front panel. After fixing this and soldering a lose power line to the power button, it's fully operational. So, with my new transport I decided to go back to my Jazz MQA-CD sample pack I got from JapanCD. It includes both the MQA-CD and regular CD of the same tracks. This time I hooked up my reference MQA DAC, the Mytek Liberty + linear power supply directly up to the amp and used it's built-in analog volume control chip, bypassing my Yaqin B-2T. This way I hoped I could get maximum resolution / lowest noise possible with my system. The Liberty's linear supply was plugged into my 500VA balanced isolation transformer, and the amp (Odyssey Kismet) plugged in to the Furutech outlet using a Lessloss Level 1 power filtering cable + Lessloss Firewall 64X. The Liberty to Kismet connection was SE on both ends. The transport connected to the DAC via AES/EBU. Testing procedure was to listen to a track, stop the CD, replace it with the other media, and play the track again. By nature this will result in a perfectly level-matched scenario. The MQA-CD displayed the effect of certain instruments and vocals appearing to be more forward / louder. Position in the sound stage doesn't change, just the more forward, as if leaning into the mic. Cymbals took on a more 3-dimensional character. Image size and position doesn't change, there appeared to be more air around it, better defined against the other instruments and vocals, giving the illusion of a more 3-dimensional presence. The bass is a little more defined; you can hear the harmonics a little better. NOTE 1: MQA-CDs from Japan are actually pressed on UHQCD. This is a new CD and physical mastering media technology which supposedly returns a stronger and more uniform signal to the laser pickup. In my previous testing with a UHQCD (not MQA-CD, just a regular CD sampler pressed on UHQCD vs the same tracks on a normal CD) I believe I noticed a minor improvement to bass definition in some tracks, so the above findings should be taken with a grain of salt. NOTE 2: as this is a sampler meant to evaluate the performance of MQA-CD, it was obviously designed to put MQA's best foot forward. Weather or not one finds the forwardness of certain midrange pleasing, it's very clear there was a significant and very noticeable difference, and the differences just weren't in midrange presentation but also in dimensionality and definition with certain aspects (with the caveat in NOTE 1 applicable). Now I wonder if there is way to analyze the unfolded MQA stream? I guess it would be possible to plug the Liberty's SE out to a 3.5mm plug into a PC or maybe my iPad, but that's going to run it through a ADC phase. How would one go about grabbing the digital output of the unfolder? I guess I can rip the MQA-CD easily enough. Les Habitants and Teresa 1 1 Link to comment

The poster thinks it's around 3dB. It's true that when I first heard a major difference with MQA a few years ago with the DragonFly Red, my first thought was: "are they playing dirty pool with EQ?" Later on someone on here analyzed MQA tracks and found no change in levels. Also if MQA really was adding +3dB (or whatever) boost I'd expect that it would have been exposed far and wide by now. Also I'd expect things like tape hiss, bass, cymbals to be louder as well, not just the center vocalist. There IS an evident forwardness in some aspects that does sound like increased volume, but it's not across the board, which is why I likened it to "leaning into the mic". This forwardness has also been reported by others here. I wonder what is it that causes that? Wouldn't the filter analysis done by others here have shown, say, energy was being added to certain frequencies? botrytis and Les Habitants 2 Link to comment
GUTB Posted January 1, 2021 Author Share Posted January 1, 2021 8 hours ago, Summit said: I guess you know what to expect from the ant-MQA crowd here 😬. I am not a member of that group because, well of all the different digital format we have I don’t think MQA is so bad and with some records it can actually sound better. Of course the problem many has is that MQA is marked as been made for audiophiles and that it has better SQ than high quality (hires) recordings, which it doesn’t IMO. My system only does the first unfolding, so my experience is mainly with that. You have your own ear and can hear how MQA change the sound of different records, but one thing I will make clear is that yes it does change the sound, and if it’s good or bad depends on record, system and preference. For most records it make them sound more artificial. For an audiophile purist the emphasis and manipulation (EQ), which can manifests as more perceived air, 3-D and clearer lead vocal and instruments, doesn’t sound true and natural with quality recordings in a high end system. The exception is IME with older duller records with can sound better with MQA. The duller and murkier the better the MQA effect is. I think of MQA as a remastering, and you know that many remastering can sound clearly inferior to the original. But sometimes if done well the remastering can make a record sound a little better. Tldr: high quality recordings MQA sound worse, although for some older records it can sound a bit better. So, could it be just the filter used by MQA? Interesting it would have such a pronounced effect. It very well be though. I tried playing back the regular CD from the sampler on my Yggdrasil Analog 2 (going through the Yaqin pre). The Yggdrasil is obviously the better DAC, that's evident in the higher quality audio. I'd say the center vocals aren't as "flat", and there's more microdetail. The difference isn't as pronounced as it was with CD vs MQA-CD on the Liberty though. I may end up having to give up on MQA altogether simply because if I can't get a high-end DAC experience with it than I'd rather just download hi-res audio where available. Also, the lack of DACs which can unfold MQA on SPDIF interfaces is a problem, that means the next upgrade path would have to be to a Manhattan II which is $6k and even $4k used is still a lot of money for a Sabre DAC. None of the other more affordable Sabre DACs can unfold on anything but the USB. And also, something tells me that all of these USB controller-run MQA implementations are cookie-cutter.

GUTB Posted January 2, 2021 Author Share Posted January 2, 2021 3 hours ago, Rexp said: I don't have a MQA DAC but the Tidal Hifi version of this album sounds clearly better than the Master version. I gave this a listen, using the Liberty in the headphone system being fed by my audio PC. It lights up green, meaning that MQA is detected but not authenticated. Comparing it with the non-MQA version it definitely shows the pronounced MQA effect: forwardness with a sense of increased resolution and spatial qualities. For example, Hedwig's Theme the violin has a resonant, open quality not just forward. It's especially evident with the string-plucks. To my ears it's significantly improved over the non-MQA version. One of the more pronounced differences I've heard in an MQA album. I also have a MQA-CD of John Williams in Vienna around here someplace I haven't even opened yet, I should go find it...

You may want to look vinto that environment ... Gustard X16 i.e were below the 400$ mark at 11.11.2020. And if you go that route, please report back if the DAC allows to bypass the MQA tech/filters on the chip ... for non MQA PCM and Hi-Res files ... Now THAT is interesting, I'll definitely look into it. I also found out about the Technics SL-G700 which is a network SACD player supporting MQA using the AK4497, which is newer than the 9018 but older than the 9038. I may look into that too.

GUTB Posted January 2, 2021 Author Share Posted January 2, 2021 38 minutes ago, bobbmd said: @GUTB and others I have NO favorite MQA albums either BUT out of being an explorer of different sound quality I invested in two "MQA" DACs a Meridian Explorer 2 and AudioQuest DFR. I for one can't tell the difference in SQ other than MQA sounds 'louder' which is SUPPOSED to make it sound 'better'. As @TheComputerAudiophile @Kal Rubinson@AudioDoctor can attest I have a pretty decent 'last rodeo' system with a definitely NON MQA( and will never be per Schiit founders) main DAC Schiit Yggdrasil GS and great speakers PLUS two very old sacd dvd-a and hdcd changers and my collection of all those HARD copies of all those formats sound better than anything that I stream (almost exclusively for ease of listening) now days. So I guess IMHO MQA is pointless doesn't sound any different to me than 96/192 does and the point of this thread as well as "MQA is Vaporware" is just humorous BS. Happy New Year and everyone get vaccinated(me and my small very old staff get ours Tuesday) bobbmd Hmm, strange. I own all three of these DACs, except I have the Yggdrasil Analog 2. With the Explorer 2 I couldn't notice any difference with MQA. I had my first experience with MQA making a major difference with the DragonFly Red, I'm suprised you couldn't notice it. For sure, there is often a forwardness in midrange like vocals and instruments but it's not louder, and it's not the only effect. The Liberty is much better DAC than these two of course, although it's not great. I tested a MQA-CD on the Liberty directly against the CD version (MQA-CD sampler comes with a regular CD to do a comparison with) on the Yggdrasil. The Yggdrasil is a much better DAC and it's evident here of course, but it still didn't have the effects I noticed on the MQA version. Certain instruments had a spatial quality and sense of higher resolution, even though the Yggdrasil pulls out more macro-details. Link to comment
GUTB Posted January 4, 2021 Author Share Posted January 4, 2021 Just listened to the MQA-CD of John Williams in Vienna vs the 96kHz version from HDTracks. They are both fairly similar with the MQA-CD version shows the characteristic forwardness in some places. The download also has a cleaner background / lower noise I'm positive that's because it's playing off my custom audio PC's battery-powered Paul Pang V3 USB card while my CD transport is plugged into normal PC's power strip. The transport which is a Chinese copy of a Wadia circuit (apparently) has a large capacitor bank so I hoped that was enough to offset the use of a noisy mains supply. Both versions sound like what you'd expect from a 96kHz hi-res album: a little bit more separation / air and instrument definition. No I haven't listened to the CD quality version yet but I've heard a lot of hi-res albums like this and I think I have a pretty good handle on what they tend to sound like vs CD quality.

Popular Post GUTB Posted January 5, 2021 Author Popular Post Share Posted January 5, 2021 Wait, I forgot that General is for non-audiophiles. It’s been a while since I was last active and I forgot about that. Audiophiles are in other sections and don’t often post in General. MikeyFresh and botrytis 2 Link to comment

Actually besides being louder, from the listening I have done, give me MP3 (closer to the original) over MQA any day. BTW, where did you get this strange DSP argument from? Wasn't the filter from one of the early DACs ripped and analyzed? How does a filter perform DSP on anything? Did you just make that up? Link to comment
