I know that the center channel is very important since most dialog is coming from the center. But, looking at the equipment listed under your signature it looks like your displays sizes are not greater than 77in. in size.

If that is indeed the case, IMO, your biggest impact would be getting a much larger display. That may mean going to a projector/screen combo. A +100in. Screen will let you enjoy a true theater experience and you will be so entranced with the image that you will not worry too much about the center channel anymore.
