I've had similar things like this happen over the years. People want to hear your system, and after about 5 minutes, all they want to do is talk, ignoring the music. I solved that by setting up a strictly audio room with one leather recliner in it, and so no one is allowed in for listening. They can listen to my upstairs system turned down low, and the audio room is never mentioned. I have no friends who seem interested in this hobby, much to my disappointment. Different strokes for different folks, I guess, as they say.
Disappointing Evening
I had some dinner guest's over last evening. I had my main system warming up just in case there was some interest from them in audio. I have a second system that was playing when they arrived. It's a Bang & Olufsen BeoSound 9000 that my inlaws gave me a few years back. Well soon enough a couple of them were commenting about the good music, so I asked if they would like to hear my pride and joy system, mostly all tube gear that (IMO) looks pretty cool with all the tubes lit up and sounds way better than the B&O stuff. No interest at all in the tube system and they hovered around the B&O loving the way the glass door opened and the arm moved to each CD. Boy was I insulted, all the time, money and energy I have in my tube system!
