Re: A question about MQA
You can label it however you want. I could care less about your idea of fun. I'm the one paying for my gear and I'm the one that determines how I make my purchasing decisions. Why don't you start your own thread about your wonderful system and explain how you made all of your purchasing decisions?

Re: A question about MQA
it's trivial to determine when hirez is real and when it's not. if you have a dac that stays native (bit perfect) all the time then......just.....listen. the best version is the source file and stick with that.
while it's rare when 16/44 happens to be the source file, it does happen. i have a few like that. and they can sound really good. but almost everything out there was sourced from higher rez than 16/44, or transferred from tape at a higher rez, and those are best heard native......100% of the time.
does higher rez sound better than 16/44? so far in my experience; yes. but i am one to always look for the best sounding versions and so have lots of comparative time doing that. sometimes MQA is the best sounding version; sometimes not. in my experience a native higher rez file almost always sounds better on my system than the MQA version. some of my high rez (higher than 16/44) is from streaming, some from my files.
overall i'm neutral on MQA. i appreciate when it does sound better, sometimes it's just different. but i don't think it's a big deal and could live without it.
politically i don't like the whole Bob Stuart/Meridian 'music czar' approach to things, and the dog and pony show way MQA was introduced; it was unfortunate. but it's actually not a bad thing, just not a great thing. with the growth of bandwidth i'd much rather see 24/196 or 24/176 become the defacto standard level of resolution.my system on Audiogon; https://www.audiogon.com/systems/615

Re: A question about MQA
MQA delivers master quality audio in a file that’s small enough to stream or download – the days of sacrificing quality for convenience are over. Visit mqa.co.uk for more information.
copied off the meridian homepage. I have no education in anything digital so can only comment on how things sound to me. Having a full meridian system I wouldn't be taken seriously anyhow. I heard a rumor some internet companies are going to start charging for bits used as more people opt for streaming services instead of the monthly $350 cable bill. Again, not knowing squat about it, in such a case wouldn't lossless compression streamed live be a good thing?

A question about MQA
Mike, I fully agree. Why to be religious about this or that format? Most likely none of them is the best alternative above any other for all use cases.
Just enjoy PCM, DSD, MQA, vinyl or tape as you please. Enjoy the variety, let them serve your enjoyment of music.

Re: A question about MQA
I’m not looking for an argument. I’m trying to understand why you have no faith in the provenance of regular PCM files and yet you have absolute faith in the provenance of MQA files. I was hoping you would share what you have learned that convinced you to have such faith in the provenance of MQA files.

Re: A question about MQA
ok, lets get real here.
with digital we don't worry about provenance. period. bits is essentially bits. it's not like there is an early version of a source file. if we have an MQA title they would have to pay the rights and so would have access to the best source file. it costs nothing for the label/artist/rights holder to provide the best source.
the whole idea of MQA is to capture the higher rez musical nuance and package it in a lower bandwidth package and possibly improve on the source file performance for the end user while doing it. there would be no rational to start with a lower rez format. the only niggle would be a dsd source file which is very rare. it would have to be converted to PCM for MQA treatment.....again this is trivial to do.
some recordings are using MQA in the original mastering, but this is also rare at this juncture. if so, then even non MQA versions are stuck with that. or maybe there are alternate master mixes with and without. this is theoretical at this point. but with digital all this stuff is trivial to do. so it's possible.
so for conversation sake every commercial digital version starts with the same source file. it's a non issue.
if you are getting files from your buddy, or CD's that are copies......now provenance is an issue.my system on Audiogon; https://www.audiogon.com/systems/615

Re: A question about MQA
Every MQA thread ends in a bitchfest. Along the way somebody mentions provenance and blind testing. It’s all very predictable.
I don’t get it. Because it just doesn’t matter.
the whole idea of MQA is to capture the higher rez musical nuance and package it in a lower bandwidth package and possibly improve on the source file performance for the end user while doing it
I happen to be one of the people with limited internet bandwidth so MQA is a good option for me. Too bad it ended up being unreliable via Tidal. The issue is with my isp, not Tidal. So I ditched it.
When I was doing some comparisons, I found it impossible to compare versions of the same work in MQA, CD, and HiRez as I’m hearing gross variations in the various mixes in each format that eclipse any differences in the performance of the transmission and storage media itself.Tom

A question about MQA
In a way, I can understand the struggle about audio formats. Usually there is a limit in the amount people have available to invest.
If people feel they have to pick one format to bet on, they’re trying to pick the “best” one. Best as in best sound, best material, best availability, best technology, best gear, and ideally at the best price. And once they have made up their mind, they might feel locked-in, and thus compelled to defend that choice.
Then there are others who are keen to learn, and do have the means to explore more freely. It’s just another perspective, not right or wrong. PCM, DSD, MQA, vinyl, tape - anything goes.
Personal experience in the format space came through buying a Meitner DAC, and ensuing curiosity about DSD. I was interested in the format, and its advantages and limitations. After some time I however concluded, that while it is a nice format, there just was too little material available I’m interested in. Hence, one might run the risk of listening to a format, rather than enjoying music.
In general, change is psychologically uncomfortable for most people. This is, as it often pertains loss of something familiar, confusion due to lack of understanding, insecurity about own positions in light of new information, and lack of clarity about about what’s to come. Counter-reaction is resistance. This sets up a platform for opinionated people, who appear not to be interested in understanding themselves. They rather take interest in insisting someone else‘s view is wrong, based on their own limited understanding. A result are these Batman vs. Superman exchanges, which serve no purpose. A completely futile undertaking, if you ask me.
While this is just a hobby, and everyone participates in the forum based on their own free will, destructive attitudes can take much more sinister forms. Then the implications are more profound. I just love this quote from French General Charles de Gaulle: “A patriot is someone, who loves his country. A nationalist is someone, who hates the others.”
As Mike L. elaborately described, it does not help when a change appears to involve some kind of scheming or lack of open disclosure, as practiced by Bob and Meridian. But to be fair, Sony’s attempt to control the industry through SACD and DSD roughly a decade earlier was not very different. Correspondingly, the reaction was also similar.“Life’s too short to listen to bad audio.”

Re: A question about MQA
While I agree with this very well formulated statement, it is rather funny to apply it in defense of MQA. If people were actually interested in -- technical -- understanding, they would realize that MQA is a fraud. It is precisely, quote, "limited understanding" that makes people embrace MQA. If you like the format, fine, but it's not because it is objectively better. It may do things that you find pleasing, but that doesn't mean they are correct.

Re: A question about MQA
Well said. This is precisely why I was never interested in "high res". Too little music available, especially in the less commonly explored spaces that interest me.
Fortunately, with more recent advances in digital technology, apparent limitations of the CD Redbook format that I had resigned myself to in the past disappeared, giving way to musically satisfying tonality and high resolution.Simaudio Moon Neo 260 DT CD Transport / MIT SL-Matrix Plus AES/EBU digital cable / Schiit Yggdrasil Analog 2 DAC / Octave HP 700 preamp / Octave RE 320 stereo amp with Super Black Box / Reference 3A Reflector monitors on Sound Anchors Signature Stands / dual JL Audio Fathom 112 v2 subwoofers on ASC SubTraps / ZenWave Audio D4 and SMSG cables / Acoustic treatment: tube traps, Tri-panels, window plugs, ceiling diffusers (all ASC), large absorbing panels (Acoustics First), diverse carpets chosen for acoustic properties: wool, polypropylene basket-weave

Re: A question about MQA
True!
And no one answered the first questions I asked when opening this thread:
Is a file FLAC 24b 96k MQAed in 96k needs a third unfold/rendering unfold? Or decoding this MQA file is enough to make it comparable to the same file labeled "HiRes" in 24b 96k?
Please don't tell me to read a book, this is supposed to be the friendliest audio forum so I come here to have information without reading a tons of stories
And again, I claim that no one can really make a difference between CD, HiRes and MQA. It is all psychological

skbe, I don't think you have to read a book and I think the 2nd unfold is only required for 24/192, but pamphlets on meridian ans roon's homepage that quite simply show the process.

A question about MQA
Al, thank you for taking the time to respond.
The question arising in this thread is, how many people on the forum do actually have the technical proficiency to discuss coding differences between MPEG1 layer 3, pulse-code division, direct stream digital or master quality authentication? My guess would be very few.
Pulse-code modulation is a compression mechanism, filed for patent in the US in 1946 and 1952. The patent was granted a few years later. NHK developed the first PCM recording device in 1967. Please note, that was before the moon landing. From today’s perspective it would be a bit strange to believe the world has not evolved ever since.
From a technical perspective, pulse-code modulation simply could not handle today’s communications requirements. It’s just too inefficient. That’s why it was superseded in professional application by time-division modulation, code-division modulation, and wideband code-division modulation after that. And the next future is already on the horizon with millimeter wave-division.
Technical evolution typically occurs when a new method is developed to overcome insufficiencies of an old one. Sometimes the new method is successful, and completely overcomes limitations of the old one. In other cases it resolves one challenge, while introducing a new one in the process. This is what happened with DSD.
DSD was successful in improving fidelity of the signal by multiplying modulation frequency. But unfortunately that increased signal bandwidth to an extent, that it rendered DSD unusable for many use cases. Enter MQA. It addresses the bandwidth issue applying a partly similar logic as DSD by working in the inaudible signal band, while also adjusting amplitude and phase distortions (as e.g. introduced by R2R recording machines).
So, is MQA the final solution and the bees-knees for all things audio? Probably not. It‘s just another evolutionary step in an ongoing process. Is it a fraud as you say? According to former Stereophile Editor and recording engineer John Atkinson, and TAS Editor Robert Harley it’s not. You pick what you want to believe.

Re: A question about MQA
The source file is the original from which copies are made.
As you are also an analog aficionado, for vinyl that would be the master tape used to produce the vinyl stampers.
With every media, independent of whether digital or analog, copying always deteriorates the quality.

it's analogous to a master tape. the master tape is the end product of assembling the tape work parts that the artist and label approve for distribution. the source file is the end product of the underlying digital recording files, assembled by the recording/mixing engineer. with digital, all the work part manipulation can occur at the recording resolution to maintain optimum fidelity in the source file. the standard for most source files these days is 24/96. some others at 24/192, 24/176, 24/88, 24/48, and 24/44. a few outliers at 24/352, or dsd at some multiple, and a few at 16/44.
many/most of today's recordings can be found somewhere at higher rez than 16/44, and those are many times the source file......but not always. it's a crap shoot whether you can track down the information. but you can know that there is no reason any commercial access of the recording was NOT sourced from that source file. HD Tracks mostly offers files at 24/88 to keep file size reasonable for ease of transfer. you can go to a number of sites and get 4xdsd, or 352/24 files. some are native 4xdsd, but most are native 24/352. Reference Recordings uses 24/176 as their source files and you can download their source files from their website. Acoustic Sounds has thousands of source files for download. you can email them and ask about this issue.
on Quboz you see all sorts of pure source file hirez streaming; and i have many of the same hirez files on my server.my system on Audiogon; https://www.audiogon.com/systems/615

Re: A question about MQA
Thanks for your definition Mike. "Every commercial digital version starts with the same source" can only be true if each of the digital offerings at different bit depths and sampling rates were remastered from the original master tapes if they were originally recorded in analog. You would need to create 16/44.1, 24/48, 24/88, 24/176.4, and 24/192 etc. source files from the master tape. For all pure digital recordings, you are stuck with the bit depth and sampling rate of the original recording. For example, if the source file is 16/44.1, you can't turn it into a 24/192 file without upsampling. My point here is that every commercial digital version can't start with the same source file unless every version above the native bit depth and sampling rate of the source file is upsampled.
And when you say "It's not like there is an early version of a source file" that would be incorrect. When CDs were first introduced into the market place, the source files were mastered in 16/44.1 from the analog master tapes. Do you think those source files still aren't being used? There are lots of 16/44.1 files on Tidal and Quobuz and I wouldn't be confident to state that none of them came from the original 16/44.1 files paid for by the record labels and everyone of them has been remastered.
I also am not buying your statement that "with digital we don't worry about provenance. period." I don't know who "we is," but I do think provenance is always an issue in both analog and digital recordings. Just as some LPs try to hide the fact they were sourced from a digital file, we should also be curious as to what the source was for a given digital file.Micro Seiki SX-8000 air bearing table, SME 312s arm, SME 3012R arn, Dynavector XV-1s cartridge, Lyra Etna SL cartridge, ARC Ref 3 phono stage, Otari MX-55 2 track R2R, Ampex 350 tape repros, Roon Nucleus Plus music server, HiFi Rose 150B DAC, ARC Ref 6, ARC Ref 75 with KT-150s, Parasound JC5 amp , JBL 4345 speakers, Viero Equilibro Level 3 speaker cables, and Definitive Technology Ref subs.

A question about MQA

April 19, 2020, 12:59 PM #82
Re: A question about MQA
The quality of source file deteriorates similarly to an analog master when you make a copy of a copy of a copy etc. Deterioration is just slower.
That does of course not happen when a lots of users download the same source file from a site. Just when copying multiple times. Think of it like making a photocopy of a photocopy.

Re: A question about MQA
I am also surprised by this.
You say that an audio file when copied say in windows (copy/paste) deteriorates the quality of the sound in it?
Downloading a file isn’t a kind of copying it locally?

Re: A question about MQA
Nobody is trying to make sense to you. Just stating things how they are. Unfortunately, SW deteriorates. Usually you recognize the effect, if you are trying to use hand-me-down SW. At some point passing it on, it just stops working.
If you have a minimal understanding of how software works, these are absolute no-brainers.

Re: A question about MQA
As explained, if everyone is downloading the same file, it’s original +1. The same quality for everyone who downloads it.
If however one person downloads the file, and shares it with a buddy, the quality starts to deteriorate. The more often you make a copy of a copy, the higher the likelihood it stops working.

Re: A question about MQA
i would say that while it's possible for a digital file to suffer corruption from being manipulated in the mastering process, i've not seen or even heard of a file to be diminished from generations of properly executed copies on the creation side.
the exception is ripping software for redbook/CD's, where there are lossy and lossless processes and various disc media that introduce variables. if you add a generation of variables to each copy event the errors will build up. but the problem is not inherent in making data file copies. or transmitting files with less that robust methods. buddy to buddy as you mention. lots of variables in each sharing event.
so we are talking about flawed methods of copying.

A question about MQA
Yes Mike, indeed.
You are a SW guy, so just humor me and try this at home: take some simple SW program and copy it. Test whether it still works. If it still works, take another copy of the copy and do the test again.
At some point your SW will cease to work, and you will need to go back to the previous version to use it.

Re: A question about MQA
Thank you for your reply. A couple of points:
1. As for pulse code modulation (PCM) predating the moonlanding: General relativity and quantum mechanics, cornerstones of modern science and technology, were discovered in 1915 and between 1900 and 1910, respectively. Your point?
2. Code division modulation was invented in 1935, time division multiplexing in the late 19th century.
3. Apples and oranges. Code division modulation and time division multiplexing are transmission schemes in telecommunication, PCM is a coding scheme. The latter is used by the two former. PCM is still standard in digital telephony.
4. MQA uses PCM. Your point again?
5. PCM is not a compression mechanism as you claim but a coding mechanism. There are PCM schemes that use compression -- such as MQA.
6. Communication bandwidth is for many not an issue these days. Quobuz streams uncompressed "high res" PCM, without problems for most users. MQA was a solution in search of a temporary problem.Simaudio Moon Neo 260 DT CD Transport / MIT SL-Matrix Plus AES/EBU digital cable / Schiit Yggdrasil Analog 2 DAC / Octave HP 700 preamp / Octave RE 320 stereo amp with Super Black Box / Reference 3A Reflector monitors on Sound Anchors Signature Stands / dual JL Audio Fathom 112 v2 subwoofers on ASC SubTraps / ZenWave Audio D4 and SMSG cables / Acoustic treatment: tube traps, Tri-panels, window plugs, ceiling diffusers (all ASC), large absorbing panels (Acoustics First), diverse carpets chosen for acoustic properties: wool, polypropylene basket-weave

Re: A question about MQA
MQA still uses PCM, that’s correct. But they are trying to take advantage of the learnings along the way in their coding scheme. That’s all I’m saying. Personally I think that is a good thing.
I do agree the MQA approach has been a bit problematic politically. But I just enjoy any efforts trying to improve things where necessary.
I’m format agnostic, and do not have any stakes in any of the formats. I’m just trying to keep an open mind.
For anyone who has followed my Brinkmann Nyquist thread a couple years back, I did a test of MQA against various PCM and DSD formats when I got the DAC. The result was inconclusive. Sometimes MQA sounded better, sometimes it did not.

Re: A question about MQA
If copying of digital files was not perfect, there would be the danger of altering of data during sharing of scientific files. But that is not the case, as I can confirm from my daily work as a biochemist with large data files related to mass spectrometry and analysis of the data. If digital transfer of scientific data, which involves copying, could not be trusted, this would create a big problem. But there isn't one.
From the Wikipedia link that Mike Lavigne posted:
https://en.m.wikipedia.org/wiki/Generation_loss
"Used correctly, digital technology can eliminate generation loss. Copying a digital file gives an exact copy if the equipment is operating properly. This trait of digital technology has given rise to awareness of the risk of unauthorized copying. Before digital technology was widespread, a record label, for example, could be confident knowing that unauthorized copies of their music tracks were never as good as the originals."
[....]
