I am struggling over which receiver to get to replace my old Harmon-Kardin av receiver. I am getting a new HD TV(either the Sony 52XBR6 or the Samsung 750) and would like to upgrade to a HDMI capable receiver to upgrade the system. I currently have 5:1 and do not plan to go to the 7:1 but I wouldn't rule it out. If you have any suggestions I would greatly appreciate it. I have been looking at the HK, Onkyo, Yamaha, and Denon receivers and can't seem to pull the trigger. Can you help?
