Second audio system in your house?

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. 

wetfeet, when you do the phones be sure to spring for a tube headphone amp.  You needn't spend that much to get amazing sound.

Actually I think it's going to happen before the second system! Any recommendations tostadosunidos? (Like your funny name) I was looking at some tube headphone amps just yesterday. One reviewer said don't get tube as one will tire of the warm sound, but I'll take that with a grain of salt.  I did see a super cool mod where someone turned an Emotiva x-100 amp into a headphone amp, cool! Not tubes though.
