Ok, well I imported an album twice, once in MP3 320 kbs and another Atrac lossless 252. I noticed almost no difference at all between the sound quality. Is there a big difference? Maybe its because I'm listening it on my computer and can't pay too much attention to the detail or something. I wanna know if its worth spending time re-importing all my albums again and then onto my mp3 player. EDIT: Also, what is the best format to use in SS? I don't care about size, nor do I care much about gapless, though it'd be nice if it had it.
