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

For me it was the Bricasti, all their gear is very special. 

I’ve always been intrigued by the Benchmark amp

I’m listening to both the BEL 1001 MK V and the Plinius SA-100 (updated in 2015 to current specs and worn replaced parts). 

They are both so musically satisfying and 3D resolving. I’ve had mega-amps in my system and the two shine with Quads and WILSON Audio Watt Puppies.

Now that I have a young one in the home I’m impressed with the low SPL detail as I listen quietly at night...this is difficult to achieve and retain a fullness in the sound warmth and tonality. 

@lpretiring The original technician(s) is still at Brooks Berdan, and they service all generations of BEL 1001 amplifiers, and just about any other brand of audio equipment:
