I just upgraded to OS X.2.2 on my iBook SE 366mhz. I am very impressed with how well the system runs on a slightly outdated machine and love the whole new system redesign. My only problem with OS X is that when I play my mp3's on the new iTunes they sound really thin and crappy. Almost like I'm playing a crappy old tape or something. I know it's not a problem with the files because when I plug my mp3 player (unfortunately not an iPod since I don't have a firewire port) directly into my speakers the mp3's sound fine. Everything sounded fine in OS 9, and the problem isn't solved by running iTunes 2 in Classic mode either. I tried turning off some of the options in the Effects section in the iTunes 3 preferences, like I read in another thread I think, but nothing seemed to help. Any help would be appreciated, if anyone needs anymore information on my problem, let me know. Thanks.
