Supposedly AIFF is the Mac equivalent of WAV files. Can metadata be stored in AIFF? If not, it's not a big issue for me.

I'm using John Kenny's Cuinas DAC. It can do some pretty sweet things with the right files.
Alan are you using a 32 bit or 64 bit OS ? If you want to try .Flacs and i recommend you try them.Try this.You need to download a small utility to play flacs in itunes.

Fluke (Mac) - Download

To run iTunes in 32bit mode, right click iTunes.app -> Get Info. There you find the option "Open in 32-bit mode". Now, Fluke For Mac can perform its magic: FLAC playback in iTunes.

I think there will be a high probability that you will like the sound of the Flacs better IMHO.AIFF's will have a little smaller file size as they are a little more compressed.As always though whatever works for you is the way to go.
