No one would ever be willing or able to do this at home, but Rives Audio, XLO, RPG, and VAC put together two identical systems in two identical hotel rooms - but with one important difference. The second room was sonically and electrically treated to clearly demonstrate how important it is to account for the acoustics of the room when it comes to putting together your home theater system. Not only was the equipment/cable setup the same in both rooms, but the demo material was synchronized, as well, so they even took that variable out of the equation. The differences in performance were definitely not subtle.
