You should alo look at the 905. It is Audysey pro compatable and has more advanced Reon controls. Both look like great machines on paper. Time will tell how well they work out. There are numerous reports of all the new Onkyo's running hot. That might not be an issue, but worth mentioning. Integra has a line of comperable units worth a look too.... you get three year warenty with Integra, but they can only be bought from an installer or dealer who installs.
