Second audio system in your house?

A thought which might keep the peace in the household; get a cheap music making machine, i.e. countertop radio of sorts for the other room if the wife likes music, and circulate in other gear into your main rig. The "second" system will sound better if it's a variety of the main system. 

I would focus on a second set of speakers if you have the space. Perhaps save up a bit more or sell the amp, and seek variety of technology in selection of the second pair.

I love tube gear now, but I also like the reliability of my car stereo which will never need to be biased or have it's tubes replaced. 

I think tube gear makes the most sense for me in a critical listening system, not in a system you keep on for hours in the background.

Yes I agree completely. I wouldn't put together a tube based system to just leave on in the background. I think there's plenty of other options for that. I'm planning on another system now for a room we have dedicated as an office, guest room and a bit of entertainment - as that's where the old flatscreen, Xbox, Wii etc has ended up. So I'd like something smaller scale but still good enough to sit down in the sweet spot and enjoy some good quality tunes. 
 I'm thinking either ultra efficient floor standers, or some small bookshelves to match up with the 60w I have. 

Another option is headphones, and it's a good alternative. Some very impressive cans nowadays. 

I'm super interested in the headphone area! I can see a set up in the house in the very near future. There's so many options/combinations it's almost overwhelming. I've been curious about the new Oppo stuff, Sennheiser, AKG, Shure, the list goes on, without even mentioning the gazillion options for a headphone amp. I suppose that's another thread. 
 For the second system I'm toying with throwing a tube buffer (I know, people will up their nose at the idea) on my SS amp, or just trade all together for tubes.
