I am no expert, but from all I have heard, Tubofun is right. ... OTL tube amps are fantastic for ESL's; especially Soundlabs. I have heard the big Soundlabs driven by OTL's and it was a match made in heaven!
I think I would add the Graaf amps to your search.
Also, this info is coming to you from a Krell lover.
