So the Yamaha is pretty awesome so far in my opinion. The sound seems super clear and plenty powerful. I haven't gone near the max volume yet. YPAO works just like Audyssey although I'm only finding the option for setting the mic up for one listening position at this point. Still sounds good all around my listening area. The Denon offered 5 listening positions I believe. No HDMI handshake issues with my Blu Ray player, TiVo box, or AppleTV, with the Yamaha, which is an improvement over the Denon. Just seems to work and do a real nice job. After owning both the Denon E300, and the Yamaha 375, I think it's safe to say they are both very capable, high quality receivers that will do a great job for those that don't need all of the fancy extra stuff that an AppleTV/Roku/Amazontv already offer. Other than the HDMI handshake issues I really liked the Denon. The Yamaha fixes that issue and I like it as well. Works for me.
