I have one system upstairs and one downstairs.
When my wife is upstairs, I listen downstairs and the other way around.
Still together after 30 years !
A friend of mine has a VPI/Audio Research/Boenick kit upstairs and a CDP/Naim 42-110/DCM Time Window downstairs.I live alone but having multiple listening locations is, I find, highly desirable - I have just come in from my ex bike shed - sun in the morning - back bedroom, sun in the evening. And, age etc has reduced my three to four full days cycling to two or three half days. So - lunchtime concert in my main room. Additionally you can spend hours traipsing up and down stairs swapping speakers around, not to mention hours fearing the few hundred quid bike shed system is better than the several thousand quid main room one. Don't hesitate, multiple systems work.

Ditto. I have recently put a conservatory system together so, with the main one and the bedroom, it’s now three. For me the fun is in getting the subsidiary systems sounding as good as possible for minimum outlay. They also work for experimenting with speakers/amps/sources without upsetting the main rig.
Quad ESL 57. No doubt in my mind.
