Didn't know that about the Marquis - don't want to denigrate the guy behind that carpeting choice, I'm sure he had his reasons, but it's a shame that a newer theater like that wasn't designed better given the advents in sound design they knew about when the hotel went up. Loved the article from Mick Potter that you linked though! He's another, like Gareth Owen, who knows what he's doing. I saw Phantom in '08 before they took out the old system, and saw it again in January of '09 with Potter's system in and it was a completely different show! Wasn't crazy about some of the stuff he changed, but I have to give the man props for what he did with vocal clarity - Carlotta's voice seemed to soar from the stage, and the scenes in the manager's offices (there's a ton of simultaneous singing and speaking from multiple performers) weren't the easiest to hear with the old system - you could hear every line in Prima Donna with the work he did.
