I am looking to the future and trying to budget for a dedicated theater and one of the most important speakers for sound is of course the center channel. So I want to build my speaker system around that. I have heard some very nice mains but the center just didn't cut it for me. I know I can use a third main for a center but I want a speaker designed to be a center and not a main sitting on its side. That being the case what is the best center channel you have heard?
