I like it, wish I could spend a bit more time in there than I do. Right now I'm averaging a half hour a day compared to the 1.5 hours per day I used to spend. In reality it feels like I've been cut off.
As much as the quieter room has helped at night it isolates you from everyone/everything else in the house. They can't hear me and I can't here them. That is of course until I turn the subs on, then there's a modest rumble outside of the room but nothing close to what it was.
In our last home the living room was the music/movie room which was between the Master bedroom, Kitchen and dining room. There was no hiding/separation. I kind of miss it, if only because I could spend more time doing what I liked while everyone else put up with my music, movies, etc.
Waiting for the sun...
