My system is in a dedicated room.
I never listen to it without eyes closed and seated in the sweet spot.
It's never used for background listening, the other two systems are for that.
I've only got one system up & running and that system has been in an evolving listening room since the end of '17. It doesn't get near as much use in this location as it did when it was in the living room, and although the sound stage is now more detailed & revealing than it ever was before, I don't think that I have near as much fun with my gear as I did when it was in my living room. But there are other reasons for that; I don't find life, in general, near as much fun as I used to.
Technically I have enough unused components to set up a second functioning system somewhere else, but a couple of years ago we adopted three dogs & besides the listening room, I pretty much give them free run of the house, and I don't trust two of the three as far as I can throw them, and that means I don't trust those two at all.
Oh well. . . .
