Hello, My ~10 year old Russound System just got fried by a lightening strike and I'm in the process of replacing it. (All the wiring and built in speakers are fine.) My system has 6 zones plus 4 more A-bus zones. I have already purchased amplifiers for the zones and am now contemplating how I provide source audio to them. (All the wiring runs to one central spot). I have all out music on iTunes, but I am FAR from an expert on how to use iTunes, and associated stuff like AirPlay, AirPort Express', etc. Anyway, here's two options I was thinking of and wanted to get your feedback. Option 1: Use a dedicated iTunes PC/Mac and add a multi-channel USB output card and connect each output to one of the inputs of the distribution system. I *think* that iTunes can be controlled to stream content to different speaker outputs, but am not sure. Option 2: Use multiple airport express' to do the same thing. I'm not sure if either of these make sense - any feedback is much appreciated. Thanks!
