I'm still confused. I have a fairly good understanding of file formats, pros and cons of each, but I've never heard somebody claim that anything sounds better than flac. Are we talking about a big difference, or a subtle difference? 20% vs 1 %? While I get that flac is compressed, its lossless compression which should result in an absolutely faithful version of the original. While I could care less about how much space they can chew up because lets face it, hard drives are dirt cheap, I just went through and re-encoded my entire cd library to FLAC not too long ago. How is it possible that AIFF or any other file format sounds better than FLAC. While I'm not necessarily opposed to re-re-reencoding my music library, I'm getting tired of doing it (this would mark the 3rd time I've done it over the years, the first time was when MP3's first came out I did MP3's, then moved to WMA Lossless, then moved to FLAC a couple of years ago.) I just don't want to do this again, because it takes forever because I have a collection of 1,000+ cd's!
