How do you save your music files? I just got a 12" Rev. B with Superdrive and AE (and extra 512MB of RAM from Crucial arrives tomorrow). Love the machine, by the way. I started ripping all my CD's to the 80gig HD, and I noticed Panther was doing it to the AAC format, unlike my old Tibook with MP3's running OS 10.1. So I got on the Apple site and learned all about AAC. My question: how many kbps do you choose in saving music files? The Panther default is 128, which is near CD-quality sound and probably more than enough. I used to use my old Tibook as my stereo with a high-quality pair of Harmen-Karden speakers and subwoofer, so I used to save files at 192 kbps because I swore I could hear the difference between 192 and 128. Do you think the difference in sound quality (if there is one now?)justifies the roughly 35% bigger file size between 128 and 192, particularly in the new AAC format? Thanks.
