I'm just getting into high quality audio and have ordered myself a set of speakers and an AV receiver. I have tried searching for this but couldn't really come up with a conclusive answer. What are my options for playing music directly from my iMac 27' (late 2009) to my av receiver? I am happy to use wired or non-wired solutions but wouldn't like to buy an AppleTV or anything. Any advice would be greatly appreciated! The av receiver is the pioneer SC-LX83 if that's of any help. Thanks!
