Just got my new iMac and I'd love to be able to connect it to my stereo system. I tried a simple 1/8" to RCA cable to connect it, but its a bit quiet and very staticy. I see that the line out jack is also a digital out jack, but I'm a bit confusde as to what kind of cable I actually require here. My stereo has a coaxial digital input I can utilize, but the iMac doesn't seem like it would have the same type of connector, even if is a digital output. Much appreciation for anyone who can clarify this for me. Thanks.
