Going to go for a Denon 1803 for £299. Was between the Denon, Marantz 5300 and Yamaha 630. I've been trying to get some time off work to actually go for a demo but i'm just too busy and so have decided to go for the Denon just because i quite fancy one. Anyway compared to my current amp which is a 10 year old Pioneer Pro-Logic any of the above will surely be a massive improvement. If anybody can tell me something negative about the Denon or why the Marantz or Yamaha would be a better choice then please leave your feedback here, thanks.
