This has refreshing cynicism so it has a little attraction for me, plus I have no idea how MQA sounds or works.......MQA is the devil in audio.
It lowers sound quality, and compresses files. It is a lossy format.
It only exists to give that Bob Stuart, of the failed Meridian Audio a pension fund, so that he doesn't have to borrow money from his wife.
NO TO MQA!
