I've done this quite a lot over the years. Its almost always much more enjoyable, with by far the better reactions, doing it for regular people than anyone even aware of the word audiophile.
Not that there haven't been some notable exceptions. One time at a party this one guy wanted a listen. Turns out he had put a fair bit of time and money into one of his own. I did what I always do and asked what kind of music he likes. Which of course I almost never have what they say, but find something similar. When the song ends I look at the guy and his reaction is, "Please play another one." The guy was beside himself with pleasure.
Just one of many great reactions over the years. Before the projector there was a TV between the speakers, kept covered with a thick blanket to dampen reflections. One friend from work kept asking how many speakers? Over and over again I told him, "Just the two." But he kept looking around at where the "extra" speakers "had to be". Finally he gets up, walks up and looks under the blanket. "What are you doing?" I ask. "I was sure there was a speaker under there!"
One of my favorites was the wife of this hard core audiophile. This guy had made it his mission to buy all the best most Class A gear he could find, used of course to "save money". Just to judge by the names you would have to think nothing could be better. I brought a CD one time, popped it in, jumped out of my chair. Had to check. Had to. He must have switched and put another CD in there. No, it was mine. Damn. Would never in my life have imagined anything could sound so bad.
So one night we're playing tunes and after a while his wife comes up to me and with the most beautiful look of incredulity says, "I could listen to his all night!"
One of the more common things that happens is people want to know why, how, is it possible??? Of course I am honest and tell them we don't know. All we can do is try and compare and select what works. Which is true. Or sometimes I tell them well there's big differences in recording quality and the ones you're hearing are way better than average. Which is also true. Which is what I was telling this one work buddy when after some Terry Evans he says you know I think that last one was even more clear and detailed than the others. So we pulled the jacket and looked and sure enough, that was the one track on the side that had been recorded direct to two-track.
Another work buddy thought I was nuts telling him flipping off breakers improves the sound. I said bring your wife over I'll prove it- only she has to bring a CD of her favorite music. Garth Brooks or something like that. So I ask her is there one track you won't mind hearing twice? She has no idea why. I go flip the breakers, come back in, still no clue, play it again.
Soon as it's over, "What did you do?!?!? It sounds so much better!!!" I look at Ron. "I didn't tell her! And I can't believe it but you're right its a lot better!"
I put on a movie one time and the first thing the guy heard was the MGM lion roar. It startled him!
I'm telling ya folks, I got a million of em!
