ALAC ftw!!! Seriously, I love the sound quality of lossless like ALAC, but on some of my music, I encode to 320kbps VBR aac....I honestly can't tell the difference on some CD's I rip. I typically (using Max) rip to both aac & ALAC, then sample a few tracks to see if there's an audible difference, if not, I keep the aac & trash the ALAC to save space (I keep all my music on my MBP HD, which is only 120GB, so I'll save space whenever I can)
