Would you pay to listen?

One hour with one system? No (unless the drinks were Krug Clos d'Ambonnay in which case I'd go listen to a Bose system).
Who is going to decide which is the "best matched system" anyway? I have heard dozens of representatives at shows make that claim - at both price levels - some of which were downright awful (matter of fact, I can think of three who should have paid me for the hazard I had been exposed to).
To get one thing out of the way, then, why will I pay entrance fee for a show such as the Munich High End (€ 10/day) even if I have to accept far from ideal room conditions, struggle with the crowd in the hyped rooms and deal with disturbing ambient noise? I'll pay for an entire day of comparisons I can otherwise not make (and gain valuable information who's making the best out of it under such conditions).

Well now, let's see. I've had a $50K system, and I listened to it for about 16 hours a week. I kept the system intact for about two years. It was nice having it. It was mine, and it was a long time dream come true having it.
But...
Those 16 hours@$20.00ea would come to $320.00/week, or $16,640.00/year. Doubled, that's still only $33,280.00!
Maybe I'd listen a little less if I had to pay for my listening time, which would lower my carbon footprint...
I think you may be on to something!

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
