Summary: I'm pretty sophisticated technically, but configuring this receiver is nearly impossible. The menus are arbitrary and incomprehensible, the documentation poor, and the two remotes almost impossible to use. The receiver keeps crashing when it tries to update its firmware. Everything about its design is unintuitive and opaque, and configuring it to get good sound out of it is very difficult without some very sophisticated professional help.
Summary: Bought the AVR 4308 in December, and its been now in the Denon repair log jam since February. No end in sight -- they again had to order "all new parts" after the first batch failed. As an owner of 4 Denon receivers, I grow worried that the first parts failed, the new batch they ordered failed, and they can't even give a MONTH or QUARTER when it will be repaired.
Summary: 2011 Update: I originally bought Denon because of software upgradeability for internet media enhancements; I was even OK when they went to a fee model for software updates under the hope that their Japanese engineers would come up the learning curve on both usability and functionality. I have since come to realize that Denon is not a trustworthy brand in which to invest significant dollars in premium priced technology products.
Caution: System Failure and Customer Service Failure

Summary: I bought this system in late October for a Christmas gift and it was faulty right out of the box. It wasn't until Jan 2nd that I had the opportunity to hook the receiver up with my new projector, plasma, HD cable, and XBOX 360 components. Once installed the audio and video was flashing on and off with all inputs and outputs.
