I can't recall which of you made the comment on another thread but thank you!!!!!!

I was fiddling around with my HT set up today and for grins disconnected the center rear and ran it in PLII instead of PLIIx. What a huge difference in sound quality for TV/DVD with either 2 channel or 5.1 channel sources. I could never figure out why I wasn't able to get my center channel speaker to deliver crisp dialog/vocals, there always sounded like there was a phase issue or something else muddling up the works. I had checked repeatedly to make sure that all speakers were in phase and had adjusted the Center EQ feature on my Yamaha rx-v450 endlessly to no avail. After ridding myself of the awkwardly mounter rear center (wall/ceiling boundary directly overhead) it was as if someone pulled a sock out of my ears. The improvement was that dramatic. Continuity during left-right pans in the rear channels was also greatly improved, as were back to front transitions. I now can get the sensation of something flying in from directly over head and toward the TV despite the fact that my left and right rears are mounted at just a tick above ear level to either side of the sofa. Previously, overhead sounds seem to come partly from both left and right rears with a hole in the middle. The depth of images in front of the listening position is also greatly improved.

Hope this helps some of you out there. It sure made my day.
