A couple of years ago I revamped my home theater system. I’m looking for advice on how to determine/maximize surround separation. What I currently have is: * AV Receiver = Yamaha RX-V463 * TV = Samsung 52” LCD 650 series * Satellite = Dish Network VIP 722 DVR (I also have a Roku HD box for streaming) * DVD = Panasonic DMP-BD30 Blu Ray * Speakers = L/R Front, center, L/R rear, Subwoofer Connections * Satellite Receiver to TV via HDMI * TV/ DVD/ to AV Receiver via L/R RCA connections My previous HT system gave great surround separation. I could hear R/L motion and rear sounds clearly. My current system has great fidelity, but it’s almost like mono. I have of course adjusted each speaker volume level via the receiver and I can have front/rear/R/L weighted sound, but I don’t get the surround separation of my old system or what you would hear in a theater. Each of my components has digital optical capabilities. I’ve tried the optical outputs to the optical input and there doesn’t appear to be a difference. One thing that I would like advice on is a movie or DVD that has unmistakable surround separation. Currently I’m using Transformers and/or Star Wars and sometimes I think I’m hearing separation and sometimes I think it’s my imagination. Also, a recommendation of a test DVD or something to that effect would help, but that wouldn’t test my DVR. I can of course activate the test signal from the AV receiver and I hear test signals from each speaker but that doesn’t account for inputs. Another possible problem is the hundreds of combinations of sound programs in my Yamaha receiver. I’m currently using “5 Ch Enhancer”.
