AAC or AppleLossless

I am beginning to import all my CD's to my Apple laptop and want to know which is the best format to use for highest possible sound quality. I have heard recommendations for both AppleLossless and AAC. Anyone know from experience if one is better than the other? Thank you,
Google is such a great thing... I just searched for
"kmixer bypass" and "kmixer bypass itunes" and got a lot of results...

I have not used Itunes, so I cannot comment further on the possibilities. I use foobar2k for the Database which supports these options. I could test as most others do when I get a few extra hours.

Chris - Thanks for the tip! Are you using a PC or a MAC? If it's a PC, then problem solved. If not, it's still worth trying out. I'm sure I can borrow an Airport for a day.

Mark - thanks for your kind offer to test sometime. Since the card is only $25, I'll get one to try. I'm currently using an M-Audio 410 and have another home for it. If I can't get an Airport to work, I'm defaulting to a setup like yours, and will re-rip my collection as .wav or with an openly available lossless codec.

Thanks again,
