AAC or AppleLossless

I have imported most of my files in AppleLossless with the remainder in MP3. For my purposes, the AppleLossless format does not provide any significant benefit over MP3. I listen primarily with earbuds, and sometimes through my reference 2 channel system. The iPod doesn't sound like a reference source component in my two channel rig while playing AppleLossless files, and the battery lasts a woeful 2 1/2 hours when used as a portable playing AppleLossless files, so I'm beginning to think the added battery life and storage achieved by using MP3 files is worth any small degradation in sound quality.

Aida_w, in my opinion, the iPod does not lend itself well as a reference source suitable for serious listening. It works great as a background/party music jukebox. For this purpose MP3 works just fine.

You're right, Onhwy61. Sorry.

If I had a reference quality PC based server, I'd use AppleLossless...
