Would you pay to listen?

Maybe I'm the odd one on Audiogon but I have nada, zero, no desire to listen to a $100K system. Seen them, heard them and after the initial "shock and awe" my conclusion is, what a waste.
Do they do things my paltry system won't? Sure. Does my system do something theirs won't. Definitely. Mine makes me smile for about $97K less.

I also am in the camp that you don't have to spend gobs of money for great sound. Seems like most of the megabuck systems I have heard are missing out on the fundamental PRaT to use an overworked term.
So my answer to the OP...
No

No, as there is little need too. Some hi end dealers such as Overture and World Wide have sessions every now and them where they preview new and exciting gear in the mega buck range. Often providing refreshments as well. And door prizes too boot! It can be a wonderful get together for audiophiles and enthusiast.

Then and other times if I can not afford or desire gear at that time. I do try to make a purchase of music or other items for my enjoyment and respect for the dealers time.

Sounds like you are feeling the water for a business venture maybe?

Not even if there were dancing girls and performing chimps on unicycles juggling flaming swords! Maybe if Natalie Portman was the host.
