How many of us are truly diversified

So here is my question after reading a couple of these Class D threads and how they are taking over the world.
How many of us are truly diversified in our home audio systems. How many of us have multiple systems in the home that are of different class amps or integrated.

I have Class D Yamaha and NAD 3020 out by my pool.We have a Pass Labs INT25 (A) in the bedroom.
Quicksilver Integrated AB tube in the officeAH Quliton X200 class A/AB in the living roomAnd I have a Bel Canto.One C5i in the hangar.
I am going to say I love my tube amps and the thing I like about the Class D stuff I have is I can go Cheap, Cheap on speakers. Hell they are on the deck by my pool and in our hanger (cheap old metal style hanger, rusty and almost a dirt floor).
So I was curious how many of us here have multiple systems of various classes and what is your fave.
