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

Plinius sa100 Mark 1. Put this amp on Class A Its sounds like tube amp, very very musical. It dissects music the way it’s suppose to be.This is the only solid state Amp that can make my Andra sing.

The pass x25 is also a very very good ss amp.

Best amp i've heard to date is the Gryphon Mephisto and best integrated is the Audionet Humboldt.

My McIntosh MC452, because it pairs so well with my Focal Sopra No2 speakers, which can sound "thin" and have too much treble, if driven by an amp that does not have a "relaxed" sound quality.

The best integrated amps that I have heard in my system are:

Luxman L-509u

Luxman L-595A

Accuphase E-380
