Second audio system in your house?

Hi, just curious how many of you have a second audio system in your house, and, actually use it? I've recently bought some new components and had planned on selling my old amp, but I'm still attached to it, and with a small investment, say $1000, I could get some bookshelf speakers and a CD player. On the fence about the whole idea. There's a whole lot of other things to do with $1000 mind you, so I'm not sure if it's the most sensible thing to get into. I won't even ask the wife what her opinion is, as I already know it.
