Tidal announcement

[Kunter]

The biggest flaw, or weakness, of lossless algorithms, even FLAC, is the processing power needed during playback and the time it steals from the playback buffering which then introduces timing errors... Hence the clear (to my ears) difference between FLAC and a simple Wav file... And, on top, there is the filtering issue, which is discussed here as well, which is the main reason why an upsampled version of the same 44k file sounds "better" than the original, although no new musical information is present.
What the MQA is doing is very clever, but I believe some time will pass until the dust settles down in terms of proper implementation.
