Summary: All I have to say is I owned a denon befor this and the sony is way better. It has 6 HDMI ports and I can view the Receiver interface from my tv in HD. not all receivers can do that at least not older ones the price is a little high but amazon and other online stores have it at a much lower price.
Summary: Easy to set up. Great audio/video quality. I've got it set up now with my Logitech Harmony 890 with pre-programmed macros for TV/Blu Ray/WII/ ETC. The On Screen Display feature is nice as well as the control over HDMI which allows the TV to control functions of the Receiver and vice versa.
Summary: I'm enjoying my Sony STR-DA4400ES. It's powerful and produces great sound. The on-screen GUI is very helpful and easy to navigate. The auto speaker calibration is one the big features with this receiver. Giving you an easy decibel setup for each speaker and sub.
