Aside from the technical details, I'm guessing that if MQA doesn't gain "traction" in the marketplace by the end of next year, it'll go the way of SACD/DSD.
I'm reading that Warner Music is working on converting many of the albums in their catalog to MQA, I hope that's accurate. But I'm also reading that Tidal has put "on hold" their plans to stream MQA. Not the greatest news for the format.
I must say, my AIFF files (most 44.1/16, some higher res) decoded by my PS Audio DirectStream DAC sounds pretty darn good! It would be a "hard sell" for me to abandon that DAC, especially if I needed a "microscope and tweezers" to find the improvements that MQA offers.
