I totally agree with you, I've noticed that when I ran the room correction with the Denon that my front stage was missing something and I know it's the center channel issue. The solution is to replace the RC52 with a RC64 and I am sure that the Denon's Audyessy will fix the issue and it also allows you to adjust the EQ on all the speakers individually. I think I did not want to spend another grand or so on a center and rears because they have been discontinued, but I do know that I am missing something will fix it by adding an external Emotiva either XPA-5 OR THE NEW XPR-5 and see if that will make me happy
