Nuforce is doing an LCR setup with our speakers. It's not surround though. Full-on HT setups are actually fairly rare at these things. The rooms are small, and the big rooms are very expensive, so the more budget oriented companies don't tend to use them. We did it last year, but it was kind of a pain and most of the attendees weren't that interested in HT (or at least they didn't visit our room) so we're back to 2-channel. There WAS a bit of 5.1 at the Audioholics show (Emotiva, Hsu, emptek) in Florida last fall, but that was a small show for a specific crowd.
