Why compress at all if the files are only like 1/2 of their original size?
Assuming hard drive space is unlimited (and it never is), MAC offers a few nice advantages over uncompressed .WAV files: Error detection there is no way to know if a WAV file is messed up, which is sort of a major downer Tagging MAC lets you tag the APE files so that you can easily manage and catalogue them (or just keep the info about them in a convenient place) Normalizing MAC can optionally normalize during playback so that all your music reaches the same peak level.
