I am having similar thoughts. I love my Yamaha but wonder if I am missing something by not having the newer features.
I am building a new house and we are going to move there around the 1st of February. I had thought I was going with the Samsung 650 series DLP or LCD but I think I have changed my mind due to a few things. I figure I will go with the Panasonic Viera TH-50PZ85u, save a few bucks and then I can upgrade my Denon 2910 HDMI DVD player to a new Panasonic DMP-BD55 with the extra savings. Now comes the hard part, I think I am going to have to go from a 7.1 system to a 5.1 system because the viewing area has an open back wall. I just don't want to try to rig the back surrounds to the ceiling. Right now I have a Yamaha RX-V2500 receiver that has served me well but I see all these features that with HD surround and a new form of DTS on the new receivers. So my question is " Am I missing anything with my old Yamaha ?" " I mean is it like I am really missing out on something that would make my system sound better by a considerable amount ? If you think I am, what receiver would you recommend under $500 ? Should I go 5.1 instead of 7.1 ?
I love having my Home Theater but its really not the top of the line its more of a bang for the buck system. I run Athena Audition front and center and Micras for my surrounds, and have the SVS 20-39 PC+ for my sub. If I am not missing out on some sound quality that is significant I would probably just stay with my Yamaha but if I am missing out on a lot then I would sale the Yamaha and get a new receiver.
Any input will be appreciated.
