JohnK, regarding rear speaker placement...a sofa is against the back wall. There is floor space on either side of the sofa. Wall mounting is not an option at this time for several reasons (not the least of which is spousal approval).

regarding your 3.1 HT comment: I agree and you have hit on the nub of my questions. Is a 3.1 set-up going to give me what I'm looking for (enhanced movie watching) or should I just back off the HT idea and concentrate on a stereo system for my music listening.

thanks, jerry
