I found their behaviour a little odd. Of the two, one of the guys made some fair points but I think in his heart of hearts he could actually hear a difference as when he addressed Steve he couldn't look him squarely in the eye. The other chap (closer to the door) was simply being arrogant and argumentative for the sake of it, trying in desparation to argue against something that was clear to everyone else in the room just because he couldn't understand it from a scientific standpoint.
In itself debating against this type of tweakery is not an issue as this particular debate has been going on for years, but it was just the way they went about it - not even listening to Steve whom quite clearly knows his subject extremely well and also believes passionately in what he demonstrates. Unfortunately for the two guys who tried to argue their point (and not very well) Steve handled the situation impeccably well and addressed all their questions with valid answers until it reached the point at which they became unnecessarily contradicatory and argumentative, only then did he ask them to leave so he could continue with his demonstration.
Personally I found the way in which they conducted themselves to be a little out of order and not really befitting of a hi-fi show, and they could have been a little more constructed and concise in their perfectly legitimate arguments. It's a shame when things like that do happen, but it's all the more satisfying that the demonstration showed that Audioworks' point is very valid and the improvements are there to be heard by all those who listen with their ears and not their oscilloscopes.
Also, it's so clear to see that Steve, Rick and Larry are very passionate and enthusiastic about the products they sell - especially Steve who has a real hard time standing still when the music's playing. He's like a one-man audience.
