Here's another take on it, from Sixmoons.com:

Thanks -- I'd missed that. An interesting part of the story that is not widely known.

As far as I'm concerned, there is nothing wrong with Meridian trying to make money. I just don't want to be the sucker who buys into MQA and give it to them.

I’m just as engaged with my music no matter what the format. And I truly hope you are too.

There's no free lunch

In Reply to: MQA ... why bother? ... why not just use least significant bits truncation? posted by bjh on May 22, 2017 at 12:34:09:

While it is true that there is no such thing as a free lunch, the converse also holds true. While MQA discards the lower bits in the baseband of a true high-res (eg, 192/24 LPCM) source file, they are replaced with losslessly compressed bits from the dual-rate band and lossy compressed bits from the quad-rate band. Both of these "foldings" represent data that is correlated with the music. Therefore even though an MQA file is a lossy representation of the original high-res file (as information theory dictates), it does contain more information than would be by simply truncating the bits of a single-rate file. In other words, a 192/24 file fully hardware decoded by MQA will have a maximum resolution of ~192/17.

If one believes that bit depth is the most important parameter, this would not be much of an improvement over a standard Redbook (44/16) file. On the other hand if one believes that the sampling rate is more important (as do I, as it allows for much gentler, less destructive filters), then there is a benefit. However why not have your cake and eat it too? At the Munich show Qobuz announced a third tier (above Redbook FLAC Sublime) called Sublime+ that allows for full high-res streaming of files up to 192/24. An interesting note is that this costs more money. The implications is that those who set the pricing (largely the record labels and copyright holders) apparently value true high-res files more than MQA files, as the price for MQA files is the same as the price for Redbook files. Possibly a case of getting what you pay for.

MQA's argument is that the bits that are discarded (and replaced by other correlated bits) in order to reduce the file size are inaudible. That is precisely the same claim that was made regarding MP3 - sonically indistinguishable. My most recent technical analysis (with minor corrections from previous posts being noted in the paragraph beginning with "NB") is in this post:

As always my posts reflect strictly my own opinion and not that of my employer, family, or book-club members.

James, with all respect, to you and BRYSTON , the music industry has decisively decided otherwise, an alternative format, unanimously. Regardless of the criticism, and respectively so. As all past formats being introduced have been subjected to. Just saying.

I disagree of course - time will tell - but so far I am not convinced this will fly. It a closed system and not needed.

I was seriously intent on buying a MQA hardware enabled DAC. After a couple months of research I decided to go with a non-MQA player that focuses more resources (engineering/parts) on playing DSD and PCM well. It's my understanding that Tidal can software-unfold MQA whereby some benefits of it can be experienced. I'll buy a MQA DAC later of good quality (but much cheaper than the TotalDac d1-twelve) to play around with and hear what my ears tell me.
