From information theory perspective, MQA is an absolutely relevant and sane solution. FLAC is competitive at moderate recording rates, but quickly looses as the sampling frequency increases and noise shaping kicks in. I think Bob Stuart is actually correct here - active information management is required (as has long been recognized in video transmission). As we say in Russian - "mansr and JimA are nurvously smoking in the corner."
I don't smoke.

and if they really want to get some idea of the Information Theory I can recommend a good (free) book, from, ahem, here
