I've been looking at the Denon AVR-3802 and the new AVR-3803 receivers, and for the life of me I can't figure out what the difference between them is? The 3803 is an average of $300 more, but I can't determine what advantages it has, other than it is the latest model. Even most of the reviews I read tell me to get a 3802 for less than the 3803 if I can "still find a 3802". I was just wondering if there is a big difference in the 3802 and 3803 besides the price.
