Of course. There will be specific needs such as yours, and I am sorry it limits you and others currently.
May be time for a new AVR? I just bought a Denon for about $400, and it does Pandora all by itself when it's not doing TV duty or Airplay.
There really isn't any place to put another AVR. The one hooked up to the TV is very good and it is in the family room, which is open to the kitchen and covers the whole main floor. It also covers my office, but I do play my itunes or stream from the desktop when in my office. But most of the time I am in the kitchen or family room, thus wanting to use the sound system in there.
Anyway - don't want to hijack the thread. Thanks for the suggestions!
