I too own a Denon 3803 and two weeks I ago got my 2910. I got my mind on the 2200 but the availibity of the 2910 at a very good price with lots of improvements made the choice easy. Audio quality is very good which is for me the most important usage of the 2910. Video quality is the best you can get for this price and it is very good. HDMI an DVI interfaces make it a good choice for future plans for a bigger screen/projector.
I'm very satified with the 2910 and am seriously re-discovering my cd collection again.
