I don't understand how a company like Denon must be aware of the numbers of people that complain about their manuals, but do nothing after years and years.
Smarten up, Denon! Your receivers are respected. If you put that last bit of effort into good manuals, people would recommend your products even more! Hell, most of the stuff they come up with for one manual can be pasted to others. They don't have to reinvent the wheel each time...just do it right once and modify it for each model as needed.
And I'm not a Denon-basher...I have a 3805.
