FLAC is lossless. If you encode a .wav to .flac then decode the .flac back to wav and do a full binary compare between the original and the wav-flac-wav copy, the files are identical. If someone thinks they sound different, then either they're imagining it or the FLAC decoder/player is broken or there are malign spirits in the system.

I think supporting FLAC would be an excellent change.

Doing so would also allow the audiophile library to be around half or a third of its present size.
