What is it that you don't like about your Listening Room ?

Too small, but it can sound great.

I do find that a decent size area rug and long curtains help out a lot.

Well, I've laid out a lot in the speaker thread, but I'm most fortunate and happy with my main 17' X 28' room.

My second room is 15' X 13', and has its challenges, as components tend to sound quite hard, and I often go through periods where component changes yield less difference than they should.  I also have a third room, but I don't put as much effort into that

More than anything else, experience shows me the room takes the position as the most important component, by far

Too cold in winter.
