WAV vs. FLAC vs. AIFF

Generally WAV is the best sounding with AIF a close second place and FLAC a bit behind AIF. The problem with WAV is music tags and meta data do not follow the file. It can be very challenging with AMARA and Pure Music when you cannot find the name of the song and you have have search by song numbers.

There is no difference other than metadata. If anyone thinks there is, they need to get a life or better gear!

To add depth to this discussion and to not hijack it, what settings are the best if you use WAV? Which settings for FLAC, which settings for etc.?
