I agree with Cdwallace3...."If your center channel isn't improving the quality of your soundstage, you're system isn't set up correctly."
I'll just add that I have been fooled many times into thinking I was watching a movie in Dolby Movie IIx mode (center fully engaged), and enjoying it, only to notice that audio was set to 'Stereo'. But, every time this happens, it sounds better when I switch to the Movie mode, and engage the center. There is no way two horizontally arrayed speakers can compete in terms of precise localization of the image, no matter how good they are, if the center is of equivalent quality and properly set up.
