I can't seem to get a handle on what tcheater wants to do. It almost seems as if he has a stand alone theater, speakers for a plasma that will double as DA music, DA in library and DA outside.

If this is the case then 1) use Niles piece for theater if you like it. If not use a mx-800 or 3000. 2)use B&K 310 for library, exterior and plasma with B&K keypads for all 3 places with a mx-800 or 3000 for the plasma. stick you equipment in a middleatlantic rack and let it roll!
