I have huge skepticism about MQA. I visited Meridian and their MQA suite at CES.
1) When I visited the suite I was given a demo of MQA. How? They sat me down and played some Ella, Sinatra and Norah. Period. No comparisons with MQA on and off? Nope. The system was nice, the room was a rather quiet suite, the speakers were very nice Meridian floor standers...but the rep said they weren't doing MQA on and off demos cuz this wasn't the best environment for it. Huh?? If I am being asked to buy new hardware and yet another copy of Norah, Frank and Ella (own all three demo albums where the demo cuts were from, for example) I'd better be able to hear the advantages in a crowded bus, let alone a quiet high-end suite. Or just give me headphones...something! And I'm in the industry...
2) Another copy of all these premium-priced albums...again?? Let alone buying new hardware? Good luck, Meridian. That's a huge selling job you've got.
3) Insiders say the process of storing the extra hirez info in the tagghing area (keeping unprocessed files from being non-compatible) is a somewhat lossy process. Hmm...
Stay tuned to this. I don't disagree that Bob and Meridian have earned the benefit of a doubt.
