Here is another dilemma.. If you connect a line out from the main home theater a/v receiver to an amp, then to a 6 way speaker selector to provide sound thoughout the home, then you can only listen to what is currently on the main home theater a/v receiver! If you want to watch a movie in the theater room, and listen to other music in all other rooms, you can't. This is assuming the amp you are using has no other inputs for components. What if, however, you take either the pre-out of zone 2 on the main a/v receiver, or the actual left/right speaker outs of zone 2 from the main a/v receiver, and then connect this to the amp? I am guessing that this will allow you to safely play zone 2, which can be another source, amplified throughout the whole home. And, if you would also like to listen to the same thing in the theater room, all you have to do is switch to that input on the main zone. Is this the way most of you handle this situation when you don't have a dedicated multi-zone amp?
