Chiefly, I want to know this. the mini doesn't have an optical out. it does have an "airport" which is a wireless device that connects to my amp with an optical out. 1. because I'm buying a 'new' mac mini with BT and Airport built in, do I need ANY other piece besides an optical cable to make this 'airport' thing work? 2. how does this affect the sound? 3. is there anything I can hook to my SB Live card (PC) so that I can connect it to my amp and get digital music? In case you haven't gathered yet, I'm looking to play iTunes music on my home stereo. I've hears that this is easier to do on a mac, and this is one of the main reasons I'm looking to buy a mac. Thanks.
