My wife just laughs these days at my illness, I mean addiction, er, HOBBY! That’s it!
I have the main 2-ch system in my informal office (read: living room), a small 2-ch in my actual home office, the basement home theater, another small 2-ch setup in my equipment/work room, another old 2-ch in the garage, and a soundbar for the family room tv. And my daughter has the 2-ch system in her room that I got her for her bday. And I’m getting my son a system for his bday. Outside of bathrooms the only room that doesn’t have any type of system in it is my wife and I’s bedroom. Go figure.
