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

The FM Acoustics 1811
At Munich High End this year. To me, it is bar none the best transistor amplification on the market. Quite possibly the best amplification period. That room was best at show. After it, everything else was boring.

Bakoon Amp 13R.  A remarkable amp at 25 watts per side. This is where my amp search ends. 

Any feedback on heff rowland 1500 wpc integrated ?

D'Agostino Momentum M300's.  I was at Echo Audio in Portland and Kurt had these set up to demo and let me listen for a while.  Way out of my price range, but wow.

To me it’s my Krell FPB 600. Plenty of power when called for  , Big deep bass , Excellent detailed. Excellent in all areas for me. Everything I could want in a ss amp.This  amp is hard to beat.
