Summary: Bought this item used. New was $1400, refurbished from Sony was $1200. I got it for $500. Delivery, etc. was fine, and all of the packaging was there. But after the receiver is on for 15 minutes or so (which I did not notice for awhile) the receiver generates a distinct buzzing.
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: I have owned this receiver for more than a year and I have been wanting to replace it since I plugged it in. The first thing I noticed was the persistent low hum - when the unit was off. I figured it was some sort of setup issue or maybe another component causing interference.
Summary: I have spent about a week with the 4400es and it is without a doubt a great and versatile product. I have my cable box, pc, wii, ps3, xbox, and hd dvd all hooked up to it. It all sounds and looks great. There are however some limitations you must be aware about.
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: There is not another brand on the market that can do what this one can, but it still has a lot of limitations and notes on every page of the manual. The manuals are available on the Sony web page under support.
Summary: The "award winning" GIU is lame and slow. The XM input broke off the circuit board. Because it is "physical damage" its not covered under warranty, even tho it was never soldered to the board. The sound is amazing but not for the price.
