It isn't the biggest show on the planet but this may not be the best forum to decide its relevance. It takes place in Montreal, Quebec, and a substantial number of the people in attendance speak French. There isn't a lot of French on Audiogon. Also the show is in Canada and while there are Canadians on Audiogon there are not that many I am one).
If the show is irrelevant than I imagine it is the retailers, who will decide that.
