Best amp for Meadowlark Blue Herons?

No I have not. What would I gain over the the solid state?

Your other thread on the same topic has garnered a few suggestions involving tube amps too.

I have Shearwater Hot Rods. I've run them with a transistor amp ( SimAudio ) and with my current tubes. The transistor amp had terrific authority in the bass but the tube amps made something I consider closer to music: natural flow, plus a sweetness to timbres and a kind of three-dimensional presence to the instruments.

What kind of tube amp did you use?

What about a Modwright KWA100 SE amp?

I've used Shanling SP-80 monoblocks. Currently I have Audio Space Nova M monoblocks with EL-34s. These are rated at 60 watts. The BAT tube amps are also very good.

I'm afraid I don't know the Modwright. I have heard the Herons with SimAudio transistor amplification and thought the combination remarkably good. I still have a soft spot for tubes.
