I have a 2009 Mac Pro and I recently went to a couple Dell monitors and lost my speakers. In my office I have an Apple TV hooked up to a nice surround sound system. The only problem, is my Mac Pro doesn't support Airplay. Also I don't want to run a 30 foot cable from the headphones into my receiver. One thing I'm considering is hooking it up to a Sonos Play 5. I already have 4 sonos speakers and love them. Any other ideas or suggestions? It would be nice to take advantage of my surround system (which would mean no sound while working and watching movies which is ok).
