Not ever having heard a "bright" system (and yet having had Yamaha and Outlaw components in my system that *other* people say are "bright" ...)
I would *think* that the largeness of the room would offset the "brightness" somewhat. I.e., sound level drops off as a function of the square of the distance so that a bigger room would have less of a problem with brightness than a smaller room...
