ASC WallDamp

Just starting on a room design for a dedicated listening room. Lots of decisions to make of course; this room will be part of a custom built home and I have considerable leeway in room dimensions. My current room is 17.5w x 26L x 9h. My new room will be at least this big and most likely a bit larger.

Has anyone actually utilized ASC's WallDamp system in a dedicated stereo listening room? There are several different install options (single stud/single plate, single stud/ double plate, etc...) Which wall construction did you use and how happy were you with the results?
