How many systems do you have?

Two,

Main system downstairs and the Office.

I hate to say it but I am listening to the Office more than the Main.

B

800 sqf condo here so just the one and it's plenty enough.

4 and 2 are used daily.

I don't think that "syatems' include PMP's.

One sound room , typically 2 systems going, one SS one tubed.  5 turntables though :-) 

Good Listening
