I am thinking of upgrading my reciever and speakers and would appreciate whatever suggestions I could get. I have a Sony "box" system now which isn't bad, but there are some things I wish I had. For the reciever I would like to go 6.1 And try to stay in the $600 range give or take. The speakers I am really not sure of. I have Sony now, and don't know any better. I want the smaller bookshelf type, don't know what to expect price wise. I just want a nice middle of the road system nothing to extravagant but not cheap either. My room size is 17'x20' approx. Couch is against the back wall (don't know if that is bad for 6.1). I have a Mitsubishi WS-55 RPTV that I really like. Any help is appreciated. Thanks.
