Nobody is going to sell their 10k dac they’re impressed with to try mqa.
MQA is the wrong format to care about. It says it folds sample data into fewer samples to take less space, then the secret way unfolds them back, and won’t let you encode it, only decode it, or else you might just find out Tidal actually doesn’t have any original higher than 44.1 res files. They didn’t think people would be able to know the difference true higher res streaming would make that way. And you still don’t. If you are using Tidal right now, and the track is supposed to be higher res, you don’t know what it should sound like if it were not mqa
SACD is not dead, it prospers as even higher bitrate dsd files. They're up to dsd256, up from the original 64, so far. There's probably higher already, my dac can do 512.
