You have to consider (and you seem to know this) that you did not listen to just loudspeakers, but a complete system. So you have a totally different chain of electronics, different cables, and a different room, any of which could cause the effects you've described.
The only true way for you to know how good or bad the speakers are would be for you to borrow them and install them in your own system. That would be the basis for a solid opinion as opposed to much speculation and doubt.
The main thing you can take from the demo is that the speakers have wet your apetite to see what more they may or may not be capable of...
