On the topic of metadata - having invested tons of time to rip my files to WAV, I wished I had started with FLAC instead. Transferring any WAV files to another device, I invariably lose album and track data and have to rip again, or worse, I end up with incorrect data when I try to synch with Gracenote. I too chose WAV files based on listening tests, but in hindsight - hard drives fail, you will need to copy onto new devices, and FLAC keeps the meta data intact.
