Just got a 52" Samsung LCD HDTV along with a Sony Blue-Ray Player....Ok, with that in mind...I am looking for a Good Decent Home Theatre System ($500-$600 Range)...since I already have the Blue ray Player.. I would think that I could just get a Nice Surround Sound Receiver with a 5.1 Speaker Setup, Correct ?...I wouldn't think I would need a "Theatre in a Box"...since those Packages already have a DVD Player in them...any Recommendations and Advice would be Great...Thanks
