I have been a big fan of Denon for a while, they have always had a fantastic reputation, but at a premium price. As of recently, their receivers have really come to the front of the pack, and the 4810 is no exception. I have a lot of experience with the 3808 and have nothing but positive things to say about it.

And then there’s the latest Audyssey entity, DSX enhanced surround, which augments standard 5/6/7.1-channel layouts through synthesizing new width and height signals to send to two or four additional speakers. (The AVR-4810CI has nine onboard amplifier channels, plus preamp outputs to drive a separate amplifier in 11-speaker surround setups.){/joomsay}
