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

I found Accuphase P4500 for my setup as the best amp in many ways! If you can tolerate >200W class-A constant heat, then try Accuphase A48.

Definitely Dartzeel. Both the  stereo and the mono blocks. 

D'Agostino, Ayre and Luxman.

The Luxman and D'Agostino were very close.

Ayre is a different animal altogether, and, oddly, sounds a lot like Arcam.

IME, synergy is the single most important element in piecing together a system. And amps are no different, especially when it comes to pairing them with your speakers. What sounds best in one system may sound like crap in another system. 

After trying few SS amps, i have heard nothing as magical and transparent as Accuphase E-650. It was simply a match made in heaven for my Tannoy Canterbury’s.
