Your difficulty with MQA seems to be philosophical or ethical. I can't argue against that. Sonic benefits is exactly why those opposed to MQA are opposed. We want to preserve the availability of quality music, now and in the future. As far as ethical reasons, the way MQA has proceeded from day one has left a very bad taste for many.

I was very unimpressed by his earlier anti-MQA hobbyhorse and responded to it in detail which went without substantive answer, I'll see what he's come up with now. Weather or not MQA's time domain is fakery is not something which can be determined by looking at a frequency plot of a rendered MQA file. As Jim Austin -- a PhD in physics -- over at Stereophile commented that the only way to test the time domain claims is with the participation of MQA Ltd. No one here, and not Archimago, has the ability to do so. Setting aside whether or not MQA sounds better, it seems that everyone who has actually listened to MQA through a MQA DAC reports that it can sound very different. Many albums I could detect no difference. Many albums I could detect only a slight improvement. Some albums have shown a huge difference, the first one such I was immediately suspicious that there were EQ-ing going on. I have since then begun to suspect this perception of increased volume, or forwardness, as if one were leaning into the mic, is an illusion from improved time domain performance. I noticed that in my vinyl system, many of my records displayed a clear and obvious improvement of dynamics over the digital versions of the same album. This is what has sent me chasing after a digital solution to this gap for the last few years. I wonder if what I was actually hearing in the records was the correct time domain information. You can't blame different masters either. Hit up Tidal for Confederation: https://tidal.com/browse/album/50641444 This is a Sheffield Lab direct-to-disc recording, the album was directly transcribed to wax in real time with the performance. Completely analog to start to finish. The Tidal version is essentially a needledrop done by a professional mastering engineer. Now when you listen to this album, you'll probably find nothing wrong with it. It sounds fine. Except you have no idea what the record from 1977 sounds like. It's a different experience. It may give the impression of being more forward, but in reality, it's the sense of reality, of higher highs and deeper dips, that dynamic power and contrast which is so pleasing and life-like. Everyone knows that vinyl is nosier, more distorted, has less (usable) bandwidth, etc. So what is it? What if it just boils down to the lack of timing errors endemic to digital? What if Stuart's theory is correct and it's this timing information what actually makes hi-res sound better than Redbook? I put as much credence in these observations as I have put in every observation you have made in the past.* *When I have not had you on ignore. MQA is not allowing independent comparison of their product for the alleged reason that they are protecting intellectual property. They are not allowing independent comparison of their product because they are protecting the very carefully constructed illusion that MQA provides a benefit to the music consumer. MQA is terrified of independent examination of their product because the truth would come out. Much of the truth has already come out and MQA is scrambling to cover up the truth. maxijazz, Anonamemouse and MikeyFresh 3 Boycott Warner Boycott Tidal Boycott Roon Boycott Lenbrook Link to comment

However I've suggested that you need to give it consideration, and understand why your having bought an MQA enabled DAC (you are personally invested in MQA), and also bought into a bunch of pure BS marketing-speak from an entity that stands to benefit financially from this scheme (Uncle Bob and co.), and your quoting of the perceived higher authority of Jim Austin et al. means you've drank a healthy dose of the Kool aid, your expectation bias likely now drives what it is you think MQA sounds like. But I'm not expecting much from you here GUTB, your past posts on this board and your recent dismissal of Archimago's very well informed/written 3rd party opinion on MQA that has never been successfully refuted or rebutted in any way, means you are very likely a lost cause. Ditto your infamous and fully uninformed stance on Class D amplification, as if all such designs are the very same thing, and equally bad. Thats scary dogma and willingness to retreat to a comfort zone supported by the old guard audio press. So I expect you'll reject the McGill study too, but not by means of any informed or competent critique/rebuttal. I now return you to the Ignored member list.

I take it that in 2 above (MQA Renderer only) and 3 above (MQA Decoder + Renderer), the DAC is simply displaying the source sample rate (and not the output sample rate). But it's weird that in 2, the DAC displays "24 bit" and in 3, "16 bit" (Is that also by design?). I'm guessing that in 2, where Roon is doing the decoding, the DAC first sees the 24 bit stream, displays "24 bit", and the subsequent rendering by the DAC does not change "24 bit" from being displayed. OTH, for 3 above, the DAC first sees the 16 bit stream (undecoded), displays "16 bit", then the DAC's full decoder kicks in but does not change "16 bit" from displaying. (This is very confusing for the end user.) mQa is dead! Link to comment

When Roon's MQA Core Decoder is engaged (Settings->Audio->Device Setup->MQA Capabilities = "No MQA Support" or "Renderer Only"), 24/88.2 (in the case of 16 bit MQA) is output to the DAC, i.e. the DAC sees 24/88.2 (not 16/44.1). Let's assume your MQA DAC is setup in Roon as a "Renderer Only" and you are playing a 16 bit MQA file. The DAC will display the source (pre-MQA) sample rate*, not the actual sample rate input to the DAC. Therefore, when the pre-MQA sample rate is 44.1k (i.e. MQA 44.1k), then the DAC will display 44.1k. Likewise, if the pre-MQA sample rate is 352.8k (i.e. MQA 352.8k), then the DAC will display 352.8k. *This is hard-coded in the MQA control stream. MikeyFresh 1 mQa is dead! Link to comment
Abtr Posted December 16, 2020 Share Posted December 16, 2020 I have a Tidal subscription and I'm thinking about switching to Qobuz. What I'm worried about however, is that the labels (Warner, etc.) will also provide Qobuz with MQA files which will subsequently be streamed without a 'first unfold', as 44.1K or 48K PCM with severely compromised sound quality (this can be clearly audible). IIRC it was discussed and confirmed about a year ago in this thread that Qobuz was streaming a couple of MQA albums without indicating this or even being aware of it.. I'm not prepared to buy an MQA enabled DAC just to check if albums and tracks from Qobuz are genuine redbook files and not (undecoded) MQA. Current audio system Link to comment

I'm not prepared to buy an MQA enabled DAC just to check if albums and tracks from Qobuz are genuine redbook files and not MQA. When I get my decoder perfected (it is getting closer), and they continue distributing recordings exactly like previous, then the decoder can partially overcome the distortions of MQA plus then some. The decoder is an advanced expander which mimicks fairly closely the kind of compression applied to almost* every recording sold to consumers. Even just now, on an ancient recording where I have master tape copies, I found the obnoxious compression added to it. * I have found a few recordings that are either challenging or cannot be processed by the decoder -- but those are relatively few and far between. The decoder is NOT for the faint of heart, and is more intended for those very, very focused and computer savvy audiophiles. Once fully perfected, and I document the internals, the source will be available for plug-in developers to use. Sadly, the software is far, far, far beyond a typical 'plug-in', but at least the technology will be there for the taking. People are JUST NOT getting what they are paying for, whether it be MQA distorted materials or other previous schemes (since the middle 1980s.) The music industry does NOT want you to have a pure copy of their 'family jewels', so they try to pawn off a somewhat damaged facsimile. This whole thing is sad, whether it is MQA or the farse about 'remasters' which are seldom much better than the original, original digital release. You probably have to go back to vinyl made in the 1970s to get good, undistorted quality. Even then, the industry could take advantage of vinyl damage to keep the pure, accurate intellectual property out of our hands. Link to comment

I think that is the plan anyway.. Unless Qobuz agrees to buy an MQA license for doing the unfolding to 88.2k or 96k PCM, most of the Qobuz catalogue will be degraded to undecoded MQA instead of redbook. Note that sound quality after the first MQA unfold is generally quite good and sometimes better than the latest re-remastered redbook version, e.g., if the MQA version is based on another mastering or even on the original release.

And this does make some sense (at least in MQA mythology) where the source is MQA 88.2k and above.
