I think the show is being under promoted! What do I mean? If I were Joe, I'd be following up with everyone who has already signed up (like me) via email and asking us to let our friends and relatives know about the show (he hasn't). Also, if I were Joe, I'd be asking every sponsor to send out similar emails.
SVS, OSD and now PSB Speakers are Gold sponsors...I'm pretty sure that (combined) they have a massive contact list that they should be emailing just a simple link to the show with an explanation of what it is and why they are in.
A couple more things:
I posted information and links to the show on Audiogon and AudioScienceReview....those posts got very little traction...either I did a crappy job posting or those site members are so interested in arguing about almost everything...that new things like this show don't matter so much???
Also, the show timing is good in that the industry needs something new...and it is bad because as everything opens up, people are more interested in getting out than in spending more time on the internet.
And finally, there may still be a little bit of fear/concern about spending money...yes, the stock market is back....yes, some jobs seem to be coming back....but every day, the media seems intent on telling us that more bad things might be just around the corner!
