To completely dismiss a demo at a dealer is an extremely narrow minded approach. While room interactions cannot be accounted for in such a demo, it's assumed that if you're buying a serious piece of kit you are also serious about the acoustics of your room and have it properly treated. As to the actual sound of the system, as long as a person is familiar with the components in front of the speakers, side-by-side comparisons at a dealer are an invaluable part of the purchasing experience. Frankly, I don't expect dealers to haul 150+ lb speakers to people's houses for auditions. Also, it's a catch 22 in most cases on the smaller stuff. It annoys me no end when a dealer doesn't have a speaker on demo because someone has it at their house to demo; they simply can't win. But it's also important to pay attention to what a dealer is pushing as often they will assume that you are clueless and set up the front end to accentuate the strengths of the line they are trying to push.
I can tell you with 100% certainty that if it wasn't for a dealer audition, I wouldn't have the speakers I have now; I would have stuck with B&W as that's what I know and missed out.
