I know that there are some differenes with drives, and stuff like r/w
offsets and so on, but that sounds like a huge difference to me.
I don't know much about that stuff, but I know where to find
knowledgeable people.
I'd give the hydrogenaudio.org forums a shot. If the guys there can't
answer your questions, I don't know who can.
Note that the forums focus is not on free software but on audio codecs,
cd ripping and foobar2k. I hope that they can help you anyway.

Oh, and if you find something interesting, please consider sharing it
with us.
