In the interest of making the sound better, it alters the sound the mastering engineer and musicians signed off on. MQA appears to be genuinely clever and legitimately new, implementing post-Shannon developments in sampling theory that have not previously been applied to digital audio.

For high-resolution audio, MQA compresses data into a much smaller file or stream while retaining, it is said, the sonic benefits of the original high-rez audio (and also of "deblurring").

MQA has once again floated to the surface of the perfectionist-audio pondnot belly-up as some have hoped but forced there by relentless pursuit by anti-MQA predators posing as impartial jellyfish.
