OTL amps with Wilson Watt/Puppy 6s

OK I'm in the market looking for an OTL amp to mate with a pair of Wilson Watt/Puppy 6s. The speakers are rated at 93 dB and 4 ohms. My room size is 16 x 19 x 8 so its not too large or too small. So far I have on my list:

Atma-Sphere
Joule Electra
Transcendent
Tenor

Are there any others that people recommend I consider?
