Is there not a Mac version of foobar? If so there is the iPod component that allows syncing with "i" devices.
(Edit) Got my cables (6 inch and 6 foot) in the mail today with my Psychology textbook . Very plain looking but feels well built. The only problem I have is they are quite tight which means I have to pull harder than I would like on the DF to get it out. Took an old USB hub I had hanging around and pulled it in and out several times to loosen it a bit. It's a little better but still tighter than I like. Audio quality (in the 5 minutes I had) seems the same. Haven't noticed anything different and don't/didn't really expect to.
