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

Luxman m900u (in an all Luxman system) and Benchmark AHB2 (in an all Benchmark system). Two different sounding amps. I loved both.

I bought a second AHB2 yesterday to run in mono. I was in fact deciding between the CODA #8 mentioned above and 2 AHB2’s.

I believe the OP’s question was, what is the best solid state amp YOU have heard? not what is the best solid state amp out there.

lol -- this makes replies even more meaningless as many, if not most posters have little history here, and do not qualify their comments and choices with disclosures of their systems, nor their experience (much less a listing of other amps they have had)

a nad amp would be the best sounding amp i’ve ever heard if i got into the hobby last year and had just a sonos amp prior, driving my dad's 30 year old advents ... 🤔

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.
