First-time poster. As I drift away from mp3 and AAC, I've been enjoying my music in the Apple Lossless format being an iPod person. But the one thing that concerns me, given how opaque and consumer-oriented the iTunes software can be, is how good the program is about transcoding Apple Lossless files into .wav or .aiff later on. In theory, you wouldn't lose any sound information, the program would just decompress it...but this is iTunes, where I've learned never to assume the best and cleanest operation under the hood.
Apologies if this has been hashed out here before, but I can't seem to track anything down on the subject.
