CD or anything physical. I will never pay for digital stuff, not because I don't like digital music (actually I rip all of my cds as soon as I buy them), but because I like having a printed cd and booklet in my cd shelf
CD. Why would I choose lesser quality when I can create it from the CD?
Well, you can always decompress those FLAC files to wav...i didn't know you could buy digital .wavs outside of samples. any time i see lossless for sale it's always flac.
