That feels like something I can relate to. When I acquired my most recent full sized speaker rig, I was hoping to have somebody to share the experience with, but in reality, very few people care at all, and almost nobody wants to sit there and listen, they want to talk to you and enjoy the music in the background. Over time, I have been finding myself wanting that same thing so I am willing to make this move and see how it goes.
I cannot imagine more than a handful of times until I die when anybody else would remotely care about listen to music in the way that could justify a full sized speaker rig. Seriously, most people could care less. Same for movie watching I'll bet. Movie theatres are so loud to me that it is unpleasant, even dialogue is at an intense SPL and if there are loud passages, it truly can get painful to experience. I wonder if guests who come over to enjoy a movie at peoples home with these big, loud home theatre systems are often just being polite and waiting until their friend's husband finally gets over his new toy syndrome and doesn't try to make every gathering about his desire to show people what he has built.
The pursuit of huge media rooms and audio systems can actually be pretty a-social if what the owners really want is for people to rave about their system with them. For me, I am hoping that putting together a system that is small enough to be unobtrusive, and perfectly happy in the background is enough. If a gathering gets a little lively, great, the volume can go up, but I imagine those types of gatherings are less and less common as we age. Call it a hunch.
