AUDIO SHOWS! WHAT would you like to see more of there. Better brands, hours etc?

Definitely later hours. But it's not fair on the workers.

Trade shows are an expensive endeavor. Big or small company no different. 
The small fish need to partner up to mitigate costs. But the expense of travel, rooms, food, entertainment, especially in the big city is no trifling amount.
Setup. Teardown. Making sure everything is as perfect as the surroundings allow. 
The after show hours can be just as arduous for an exhibitor as the actual show hours. 
I hated trade shows  But they were/are a necessary evil.

Now as a participant selfishly I want fewer attendees. That is what I want. But more of… focus on the $10k and less system so we can get more youth involved. However I realize the profit lies in the big ticket sales. Ten $10k sales would not match the profit seen from one $100k sale  

Not something I want to see, but something I want to *not* hear: the standard, run-of-the-mill "audiophile" demo tunes.

I wish Geoff Castellucci nothing but the best in life, but if I never again hear the dulcet tones of his baritone interpretations of "16 Tons" and "The Sound of Silence," I will be elated. (If an exhibitor wants to show of the lower register of a male’s voice, drop the needle on Elvira by the Oak Ridge Boys, or The Shipping Forecast by Neil Nunes).

Same goes for the electronica track "Make Us Stronger" by Ghost Rider. Not a terrible song in and of itself, but after the dozenth time, it grates upon the nerves. 

Manufacturers use creativity to devise their products, they should also think creatively about the music they choose to demonstrate the embodiment of their passion and hard work.

Calvinj I would like more company to participate like Tekton speakers, different good cables. I would like Audio Mirror as well.I would like the guy playing real music in their room.
