hello all. I just bought the 809 from Frys this past weekend who price matched Amazon's price over the weekend. I am replacing a Yamaha rx-v667 which I liked but it lacked good power at high volume and network capabilities. I have noticed quite a difference in sound between the two receivers. I currently own Polk TSI 500s, CS20 center and the 505 sub. I like how both receivers sound but I'm still trying to justify my Onkyo purchase. Has anyone else here had the Yamaha RX-V667 compared to the Onkyo? I still don't believe I've had the Onkyo at it's full capacity yet. I care more about music than movies, so im wondering if I get an external amp instead of replacing the AVR, would the amp's sound take over or will I still hear the sound differences between the AVRs? I'm sort of new to higher end AV so I'm kind of a newbie. thanks in advance for input.
