I went with FLAC. Open source standard that can also be converted if need be. I’m not big on proprietary formats. Using something like EAC (Exact Audio Copy) you can make bit perfect lossless compressed copies for use virtually anywyere. If you want pristine bit-for-bit duplicates that don’t take up drive space needlessly, it’s the way to go.
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?
