I am ready to upgrade my receiver. I have found some good prices locally, but I need halp in a decision. Use will be 75% HT and 35% music. My choices are: Marantz SR-7200 - $650 Yamaha RX-V1300 - $650 Yamaha RX-V-2300 - $850 Speakers are good, but small Definitive Pro Monitor 80, Pro Sub 80, and Pro Center 100. Set-up is 5.1 and I do not expect to add any more speakers or a rear center anytime soon. All opinions appreciated. Thanks!
