I have the 3805 and personally love it. I'm not familiar with that particular H/K.
I'm surprised how much I'm enjoying the latest flavor of Dolby and DTS for music. One quibble that I didn't really fully appreciate before setting up my system is that you can't change the crossover on a channel by channel basis. I wish I could crossover my Mains at 40HZ and my center and surrounds at 100HZ. My understanding is that H/K receivers offer more flexible bass management in this regard.
Others here have said that H/K power reserves are good as well.
I know I'm really not much help, but I guess my point is that you're not likely to go wrong with Denon or H/K. If there's a decent way to print out features charts and compare them item by item, that's what I would likely do!
