Just bought one
Just bought the YSP-800 for our family / media room (not the dedicated theatre room). Anyway it's connected to the HTPC and Sat Receiver and XBOX through an optical splitter. I had read up on it and when I finally heard it a Trutone in Toronto, I knew it would pass the wife test while giving the surround capability I was looking for. Got it at boxing day prices for $850.
Anyway the room it is in is part of the kitchen as well so it is 20 ft wide, tall and about 35ft in length with Hardwoods. I do loose some rear effects due to the lenght of the room but it is still very good. Left to right imaging is excellent. Sound does not appear from directly behind but I would say it comes from about 3/4. With this side room, I sould have to add a sub but I already have a Servo15 downstairs which the wife thinks is just another end table.
Anyway - pretty happy with it for what I paid and use it for. It doesn't measure up to the dedicated theatre system I have but it's not bad and astheically it can't be beat.
