I'm with you, I don't watch movies or TV much at all. I just don't feel the content these days is worth my time to sit and stare at. But sometimes me and my wife watch an episode of something.
I do like to play rock, and 80's music, and a bit of metal in the house each day when I'm here alone. (I work from home, and our daughter does daycare now.) For most of the day it's ambient, but if I'm in a good mood I will crank it and jam for a favorite song
As far as budget, my wife is already questioning why I would consider such a system when I already bought a Bose Soundlink mini last year for the laptop. And I understand. Spending more than 1k on audio for one room borders on feelings of recklessness to me. It totally shocks me to watch some youtube videos by Hans B. and he talks of spending 20k on "system 1". So in short, the $1k limit is just emotional. I am ok with 1k speakers + $350 for the AVR, but man that is my limit.
The Car's factory speakers and my Bose Soundlink Mini II is my only audio sources at the moment. I carry the Bose around the house with me when I work in other rooms.
