There previously has been alot of discussion on hear about decoding errors w/ FLAC over time, which is why i stopped FLAC'ing my masters. To clarify, I keep the master file as a WAV, the untracked uneditted 48k (or now 24 bit) files. After that, if i am gonna make and keep a CD version of the show, i might split and flac that, as long as the master is preserved.
