I thought of something late last night. My setup in my student house is: iMac -> Amp -> Speakers I get annoyed by computer noises ruining my music experience now and then. So I thought "perfect idea, I'll use airtunes for my main speakers" (I have an AirPort Ex under me desk). That way, tunes come out the speakers, other noises come out of the iMac. Except when I want to watch a Movie... Any ideas?
