Well, sort of. Is it as good as the original, 16/44 or above? No, but that is the point. Is it darn close? Yep. Can a golden ear audiophile listening to his $6k headphone rig (like me ) tell the difference when the masters are the same (something that many skip over in their subjective listening reports) between MQA and the equivalent 16/44 or hi res? Sometimes, barely. If the music has sufficient HF content I can start to hear the HF f&^*ery that the MQA folding process introduces. But I am 1 out of a 1000, one out of a million. Most people don’t have $6k HP rigs. Most folks don’t even have Roon and/or a “mid fi” system. Most people listen to mp3/aac music with phones and earbuds made in China with about $1 in parts. For them it works.
Which brings us to the irony: Bob S background an experience was in Audiophiledom, so he knew how to sell this superMP3 to audiophiles who are always and willing to purchase anything, no matter how dubious, for a sound quality tweak that only they usually can hear. They talk about “veils” being lifted and other nonsense, and they convince themselves quite easily that the fad tweak of the week does absolute wonders to their systems.
In other words, the very people who should have been least interested in a superMP3 are the very people Bob S choose as his “market opinion leaders”, and of course he was right.
