I'm upgrading my Marantz 4200 and have brought a Denon 3802 off the classifieds. I demoed the Denon about a year ago and was very impressed but at the time it was way out of my price range. The Denon however is a couple of years old now, so how does it compare against something newer like a Marantz 5400 which can be got brand new for the same sort of price as a second hand 3802. I notice the 5400 has a few things the Denon hasn't like Circle Surround and DTS 96/24, and i'm guessing perhaps some newer/updated circuitry? Any ideas?
