IMO, just because you liked a set of speakers at some show doesn’t mean you can get the same performance: good or bad. There are many things that you have to consider before making a purchase of some speaker you liked:
1) listening room. You might have loved the sound of the Wilson Chronosonic XVX speakers in a treated room of 30’ x 20’ x 15’ but don’t think you can get the same sound in a 15’ x 12’ x 8’ room.
2) audio equipment/system synergy matched to your speakers. You might have heard these Wilson’s with $300k or more worth of equipment and you might not have that level of equipment that might be needed to get the best sound out of a certain speaker.
The best bet is to find a speaker you like and demo it in your house with your equipment to tell if you like the sound quality or not
