Second audio system in your house?

Good one Mapman.  I have my idea of the super system without losing my mind--read that as a low to middle cost car cost wise.  The other is our home theater system in the family room with AV receiver and all small Paradigm speakers and an Oppo blu-ray player.  Good enough for movies and I let my wife control its use most of the time.  My good system is in the basement and I have a dedicated room which was my wife's idea.   The only problem with that system is going to bed or just leaving that room after a reasonable time.  I have to put a limit on it.

I went the other route and from the start never really intended to have more than one system - and it would be a single-sourced system at that. Never really had the extra home space or the extra cash for another rig and didn't feel I could afford a two-front war with my sources. All of that made me feel like I was taking away from my ability to get just one system to sound great. And I knew it would have to do well at that, if I had just the one rig...handle every genre/disc/track equally well, not dictate at all to me what kind of music I might prefer to listen to, do well at all volumes, and all that. So it took me longer to build (roughly 26 yrs) and more money than I planned, but is finally coming into shape as satisfying all those requirements for me, so I feel more than vindicated with this result...even if I didn't always know exactly how I'd get there, I did manage to stay that course as it turned out. It wasn't easy in my case, but it was worth it.

But, overall, if I were ever to think in terms of having a second system, it would be in my car, not my home, but I'm just not in my car often enough to consider it worthwhile these days, really.

3 for me also. Main system by far the best of them, but bedroom system is only one I use every day. 3rd system is fun for near field listening. I use it least often, but quite extensively for a few days when I do use it.
