I’ll throw one more in the ring..
I have little experience beyond my own system..
I have 2 tube amps in rotation a Decware “ZMA”, and a Aric Audio “Super 300B”..
I like them both , but I would probably give the edge to the Aric Audio..
Priced similar around the $6,000 mark.. Both hand made by a boutique company..
On my Tektons (94db-?) both seem to have about the same power output..
Good luck in your search.,
