Hello all, I am new to the forum and would like to upgrade my current Onkyo TSDS575X reciever. After browsing through here and other forums, I think I have narrowed my choices down to either a Denon AVR4802R or a Rotel RSX-1065. I have some questions for the experts here. The Denon is THX Ultra 2 certified, therefore I am paying extra for this certification. The Rotel is not. Am I giving up anything in the Denon due to these costs versus the Rotel? Any help/guidance would be appreciated. Thanks. Also, any owners of these models out there? How are these performing for you?
