MQA sucks, it doesn't even do DRM right. I am going to watermark my music to make my friends dacs glow so they think my music is hifi. Yall can make arguments about the how MQA aligns the stars so my brain can't hear the highest octave of digital noise it adds, but guess what, I got enough noise in my system I don't need more. My wallet has chosen bandcamp for AIFF and CDs for wav, and vinyl for AAA. MQA is marketing, and is the anthesis of audio nervosa. It isn't worth arguing who understands the best theories or defending marketing. You can argue about the time domain filter optimization and the optimal methods, this isn't alien technology, it might not even be implemented in all songs! seems like Vapor ware to me. Its a light on a box.
