Hi, I currently have a Denon AVR3300 receiver, which I've had for a good few years now. I'm thinking about upgrading. I particularly want the new surround modes, and video upconversion. I could also use at least one extra optical input (3300 has 3). The obvious upgrade path is the Denon 3805. However, I was wondering just how much the audio performance has moved on, and whether the 2805 was sonically still be an upgrade for me, or whether I need to stick to the £800 price range. Any comments welcome.
