who makes a decent center channel speaker?

yes, as close as i can get it to the flat screen display. my setup is almost 'nearfield' due to room size

Another center worth mentioning is the Dunlavy SCVI...stacked vertically for best dispersion, of course.

Ok, phasecorrect, so I'm curious. Have you narrowed down your selection any? What speaker are you leaning towards buying now? Did any of this help you decide? Personally, I would opt for the Dunlavy SCVI for the money you'll save over the Dynaudio at $22k. But that's just me. I am, however, 1000% certain the performance specs and ratings are going to be higher for the single Dunlavy SCVI over the Vandersteen center you're considering.
So which is it, which is it, which is it!?!...

maggie or vandersteen

Well, I have yet to see/hear a Maggie center, other than those paired 20.1s, that is entirely successful.
