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

Bryston 4B cubed. (Driven by a BP 17 cubed preamp)

D'Agostino Relentless monoblock amps.
Naim Statement NAP S1 monoblock amps driven by Naim Statement NAC S1 linestage preamp.

Don’t be cruel but I’m an Integrated  Mcintosh fan. Built like tanks, my last
unit was 36 years old and brought good
money when I did the upgrade. 
Just love that warm un-fatiguing sound. 
I think with amps at a certain price point you’re really splitting hairs.
Now speakers are another story.
It truly is one of the most enjoyable hobbies out there. 😎

I believe the speakers have influenced my opinion but the best I’ve heard (so far) are 
1.  Burmester. Precision & detail 
2.  Soulution. Musical with detail. 
3.  T + A.  Musical with depth and precision. Prob my favorite of the 3. 

I guess momma really doesn't need a new car. Haha
