I have had mine for a little less than a month. Have been well pleased to this point. DTS-ES sounds great. I have a Pioneer Elite DVD Video/Audio/SACD with it and am quite impressed. My limited experience on this board leads me to believe that a lot of folks knock Onkyo, but I have no complaints.
I have several questions about the autio settings in the manual. If you still have your manual I can navigate to them via their menue numbers. Such as 3-3. You game?
