Second audio system in your house?

Oh Lord, won't you buy me, a color TV....
I have three systems, a Main System with BIG speakers, a second (still high-end) system with small monitors (Sonus Faber's), and a third for rock&roll in the bedroom (JBL's and Teac mini-components).
I love all three, but i only have so many hours in the day, etc. Each one does serve different purposes, Re: system#3, listening to most R&R on great (read-revealing) electronics and speakers is IMO a total waste of time, so the mid-fi of the 60's and 70's sounded (again, IMO) much better on the vinyl in the stores back then.
P.S.- Oh, i ALSO
have about 10 reel to reels- Teac, Tascam, Otari, Studer, Sony, etc.
This is NOT healthy, not healthy at all.  But if there's a pill i need to take,
they haven't invented it yet.  
P.S.S.- i have been acquiring stereo "stuff" for a very long time.

Oh, one more thing comes to mind- guitar players coin a phrase called "GAS" - or Guitar Acquisition Syndrome.  This can result in something quite similar to too many audio components.  A doctor i knew had over 40 Fender Stratocasters and Telecasters. Along with over 40 guitar cases, and innumerable sets of strings, stands, cables, amps, sound processors, and other accessories.  So we're not "entirely" alone in taking a hobby too far.
(as long as we don't forget about the millions of people who don't get enough to eat... here in the U.S.A....)

3 systems.  A Fi Audio of NY-based one in the family room; a Kondo-based one, and a Concert Fidelity-based one.  They give me pleasure, and I have an understanding (read: great) wife of almost 28 years.  I keep the Fi Audio and Kondo equipment for many reasons, one of which they represent the crucial efforts of the designers that brought them to life.  I keep the CF equipment because of the performance excellence (to my ears).  Most components were purchased at good pre-loved or demo prices, so, substantial dollars invested but not totally whacked-out - all things considered.

 Oh man french_fries, you hit the nail on the head, I seem to take all my hobbies too far. Hifi in and of itself is a bit over the top for the general masses. For example, somehow I've aquired over a dozen fine tobacco pipes in the past 6 months. I suppose it's a bit of a personality disorder. 
 Well after reading all this it appears the magic number is 3, so I'm still clinically sane (if you don't count my car) and within reason. Hell I'm basically obligated to build another at this point. The problem is, I've always wanted to try out an all tube system, and maybe a killer headphone set-up, so I can see other systems off in the horizon. 
 

I'm another one with two systems.  I have a dedicated 2 channel system exclusively for vinyl.  VPI turntable, PrimaLuna tube pre-amp and a Cary c280 V12 power amp.  ....all second-hand gear!

I have a second rig in my home office for headphones.  I have a dedicated Oppo HA-1 DAC/headphone amp and a LCD-3 headphones.  ....lossless digital bliss.
