It's interesting to see how people have taken the question in the OP in some different directions, addressing various issues like whether our personal demos have impressed guests, or even if one should care about impressing non-audiophiles in the first place.
On that issue, I understand the audiophiles who say "I don't care about impressing anyone else with my system, it's only there to please me." I think we all have that goal at bottom, but I think this also speaks to our different personality types as well. I can see how a more solitary-inclined individual would just not care much about playing the system for others. I myself am not a solitary-type. For me a shared experience trumps a solitary experience just about every time. And so one aspect of high end audio that can be disappointing is the sometimes solitary nature of it, the "one person in the sweet spot" and the fact so few people are in to it. I never try to evangelize about high end audio, but I am very much about SHARING the experience when possible and welcomed by a guest.
This is why such a large cross section of my friends, family, work buddies, acquaintances etc have ended up listening to my various systems over the years. And it includes a number of people I barely know. For instance we've had lots of contractors and installers through the house. It's pretty common for some of them to spot all the high end gear (the speakers are especially prominent) and start asking some questions "what's the deal with this stuff?" Or it might be someone who actually already has a bit of interest or knowledge themselves. So if often comes down to "you can have a listen if you want" and many take up the offer. So I've seen a lot of "civilian" reactions to high end audio.
The usual reaction is that after listening the "get it," why someone would be in to this, even if they are not going to start buying gear themselves. (My wife is the closest to an immovable object in this regard. One of the few times she sat and listened to one of her favourite songs on one of my systems, years ago, left her in tears. But even given that, her interest in my system is well in to the negative integers).
