I have a Yamaha in my spare room and currently have 2 Denons - a 3805 and 4306. I'll honestly say, IMHO, it's a toss-up as far a sound quality is concerned. I like the Yamaha's DSP effects better than the Denons, but quite frankly, I don't use either one very much. What I really like is the Audyssey feature in the 4306. Makes my whole room a "sweet spot". I don't know if it's worth the extra money to you, but between the internet radio, Audyssey, and the power, I like my 4306 the best. Only you can decide if the money difference is worth it to you.
