MQA is for chumps

Second-
how do MQA-CDs sound?  Happy Listening!

All meddling with the source signal introduces sound degradation, whether in the analogue or digital domain.  Tone controls, bass & treble adjustment, speaker crossovers, Dolby, equalisers, click and pop eliminators, MQA-like processors.  All the same.

It is impossible to adjust the sound without introducing distortion.
That is the reason for the unlifelike presentation that many people hear in digital, compared to the more lifelike analogue presentation.  The main direct causes are DA converters and clock dither.  These faults can never be fully addressed, as has been shown in the 40+ years since digital recording started.

Simple is best, leave well alone.

Clear thinker:  The “faults” have been addressed.  It’s got great sound and is somewhat ‘future proofed” with two MDC slots.  I’ll take this in both the convenience of easy integration and huge selection of artists via Qobuz, and SQ that’s better than vinyl.

Just attracting you to giving up some cash IS their business model. I am amazed that they sold any Japanese CD makers on it.
Submit them for testing before enriching probable fraudsters.

The most common problem with "digital’" is the AD conversion at the originating studio in the first place.
It is very difficult to make a purse out of a porcine ear.

Thank you for the very thorough investigation and your perseverance in doing this. For me any technology that cannot be explained in scientific terms ("folding" a digital file describes more something like magic rather than science) and does not allow independent reviewers to test it, smells like a scam to me.
Now I can see from your analysis the proof why MQA never sounded that good to me...
