I am looking at purchasing the 950/770 combo with Axiom speakers. My room is 24 X 16 with my listening position in the middle. My question is will the 950 give me the flexibility to choose a pair of direct radiating surrounds (Axiom M22)mounted on the back wall for DVD-A and SACD and then when I want to watch 5.1 movies, select my side-wall mounted QS8 "quadpolar" surrounds? Can I achieve this internally with the 950 or do I have to use an external switching box? Also with this setup, how would you go about watching 6.1 movies.Please help.
