People rave about the Panasonic recievers, but I am not sold on digital amplifiers just yet. The ones I have heard have been bright and had sloppy bass control. I personally own a Sony STR-DE597 which was the second from the bottom of it's series I believe. It sounds fine in my small living room and has some decent features. I would imagine the 800 has better and more advanced features than mine. Note the user interface of Sony's receivers can be unruly.
