Hello

Im trying to upgrade from my old yamaha RX-V740 to something new. I love my yamaha tho...no problems and the sound is awesome, but with PS3 and a blue Ray player i need something with HDMI in/out. I really dont want to spend more than $700 but i can push it to $800 if someone convinces me. Anyway so i was looking at some online:

Denon AVR-889

Yamaha RX-V765

Onkyo TX-SR607

Harmon Kardon AVR-354
http://www.amazon.com/Harman-Kardon-.../dp/B0016BGRXG

Which one would you buy? OR if you have a better receiver in mind then please let me know.

One more thing...Wat exactly is "SRS (Circle Surround II)" ? Do i need it?
