What is the best solid state amplifier you have ever heard?

Hi Guys 
Pass Aleph 0’s
Jeff Rowland Model 2

I’m Surprised that no one mentioned Jeff Rowland especially the Model 12’s which was a major breakthrough 20+ years ago. It changed the game. 

From my experience, though based on difference systems:
Bryston 4B3 and 28B3 monoblocks
D’Agostino Momentum Stereo amp
First Watt SIT-3
Classé Delta monoblocks I heard at Axpona

Funny you should ask-  
I’m right in the middle of a classic solid state cult amp shootout.  I am comparing a Bedini 100/100, Bedini 25/25, Bel 1001, Sunfire 300 and a Forte Model 4a with Soderberg mods including blackgate caps.  I usually run Coincident mkii dragons or a coincident SET, but these solid state amps are incredibly musical and I think I would be happy with almost all of these (the Sunfire being the exception) on a long-term basis.

MBL. Sweet and tubey. 
Too be, or...
