How many audio systems do you have in your home?


Curious as to how many systems do your have in your home?
I at one time or another have 3 mid to top tier sytems, one in family room, one in basement and one in main room (living room, HT room)?
Currently, my HT room has the best electronic, then the family room, and than basement.
Due to limited finance I will have to cut back on my audio toys to finance other needs, such as summer camp, summer vacation, etc. (things associated with having kids).
I am undecided in either going for a very budget minded system in family room and basement or just running speakers to those room from main room via an ABC switch box.
Are any of you currently in a similar situation or have been in such situation? What route did you take?
The family room/basement is mostly background listening.

Thx

4 plus HT -
Main listening room, secondary listening room, den, living room. Add one more if you count the garage...Its a disease I know.....
Three, and one in my girlfriend's house. Only one is really worth listening to though.
High end audio upstairs (2-channel), Home theater downstairs (5.1). Never the two shall meet.
Family room....sep. H/T and 2 channel
Office...2 ch.
Bedroom....H/T and sweet 2 ch.
Home gym....the JBL boom boom room
Garage....the current home of my first Cerwin Vegas from 1975
Also 2 car systems, 2 boat systems, and two truck systems. All but one built by me. I just love this hobby!
"Just" four:

Living room (main system) -- all tube; great for jazz, classical and acoustic music

Family room/kitchen -- vintage solid state (mid-80's tandberg and klipsch)plus tube dac and dvd/cd player; gets the job done for rock (and good enough for movies, for now)

Bedroom -- all tube again (love that glow)

Home office -- mixed bag of spare components and totem dreamcatcher monitors (not bad at all)
