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?

The Berning amps are not OTL amplifiers.

The EAR amp is not an OTL amplifier!

The Berning amps are OTL amplifers, read the technical data on the David Berning website. They are a highly advanced OTL design, I believe that is why this may confuse you. Just because this design does not correlate with other designs based roughly upon original Futterman principals and/or designs certainly does not mean this is not an OTL amplifer. Read the technical data on the website or e-mail me for more specifics which are clearly laid out within the pages of the instruction manual. This is clearly not anything like the old school of thought on conventional OTL's which for the most part incorperate "brute force" technology. There is nothing wrong with the sound or design of many of the favored OTL companies/products and that is not the point that I am attempting to make. It is my point to illustrate that the current David Berning designs represent a state of the art assault on traditional OTL design drawbacks and represent a giant leap forward in OTL design technology. Who would gripe if every OTL amplifer possessed the ability to mate with much larger varieties of loudspeakers as a result of impedence swing tolerances and at the same time retain the wonderful sonic characteristics of an OTL???

Wb6rhq brings up an interesting point here, he's kind of right when he says that the Berning is not a OTL amp, if you mean OTL in the respect of the 50-60 year old design that is still being currently used by most OTL designs.

Technology has come a long way since then, the Berning uses a RF matching transformer, the audio signal is piggy backed on a RF frequency, the transformer is therefore for the RF frequency, not the audio signal, which gets a trouble free ride, what you end up with is a new type of OTL, sophisticated cutting edge, able to drive low impedance.

So the question is, do you want to listen to music as it was reproduced 50 years ago, maybe?
The other choice is to listen to music as it can be reproduced today, with today's technology, designed by a brilliant Physicist.
