There is a reduction of 3 dB to the center channel before it is combined with the L/R, but that won't make any noticeable difference in quality.

I don't think mixing the center into L/R is in any danger of harming the signal quality.
Is this with constant direcitivty speakers?
If so, have you experimented with toe-in?

Signal compression, that is what I am getting at. As Scott suggested above, this WAS the case, if it still is, I dont know. DD you are correct about bass management, but Dolby has taken this into account while at the same time assuming one would use a center channel as well. When removing that, the decoder has to RE-compensate for a channel not being there and that is when artifacts and issues can come about.
Noah, this was with JTR t-12's, so not horns, and could have been part of the problem.
I will say after stating all the above that I preferred a phantom center setup myself before I got my A-T screen and the triple 8 for the center. When before I had major issues with any center keeping up (obviously) and placement as it was basically on the ceiling above the screen.
