Thank you all for your responses. This is very helpful since I'd like to try some downloads from sound liaison.
FLAC, WAV or AIFF question
I run audirvana plus on a Mac laptop in iTunes integrated mode. I have always downloaded AIFF hi Rez files. Another hi Rez site offers WAV and FLAC both in 24/96 resolution. Should I download the FLAC file since it takes up less room than the WAV file? Will my Mac recognize it even though I use audirvana for playback?
