Suggestions - Amps for Coincident Super Eclipse.

you could add Air Tight to your list

Because of the benign load and high impedence of the speaker, the Atma-sphere's are a wonderfull choice. With most OTL's, you will get better speed and extension than an SET.

Call either Duke at Audio Kinesis or Jennifer at Jena Labs as both are Atma-sphere dealers and excellent to do business with.

I own Cary 2A3's and Manley Retro mono blocks at the moment. A good friend has the Atma MB's which he uses with Soundlabs. I would rate the Manleys as the first choice.

I would go with a little more power in a SET with the super eclipses. You should be able to get a pair of Antique Sound Labs AQ 1006 845's in your price range. They use the 845 tube and are rated at 22 w/ch. They won a golden ear award from the Absolute Sound. You may be able to find a used pair of Unison Research 845 mono's for a little more than your budget. They are rated at 24 w/ch and sound fabulous with unusual extension for a SET. If you are interested in the Antique Sound Labs, I have a pair I will part with.

FWIW, I use an Atmasphere S30 with Alon Lotus SE speakers. Prior to purchasing the S30 I auditioned the Cary 300SE monoblocks and much preferred the S30. Greater speed, transparency and much better bass, despite being half the price of the cary's. Coincident uses the Manley retros for their show demo's, usually push-pull, at 30 watts/ch, so the S30 should be plenty with Super Eclispe. One of Atma-Sphere's dealers, Hifilogic is also a coincident dealer and should be a good source of info. Their listed on the Atma-sphere website. FWIW, if I hadn't gone for the S30, my next choice would have been the VAC 30/30($7000 new).
