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?

Chris I certainly look forward to your impressions. The Transcendent OTL amp has been a revelation in my system. It outperforms, by a significant margin, every tube and solid state amp I've listened to of late including the Rogue m-120's and Pass amps which are highly regarded in this price range. It is an incredible value at 2.1K and the performance is so good that it could encourage one to look for a speaker system to match with its limitations.

I am considering the Joule VZN 80 for my Merlin VSMs (the choice of Bobby P) and would certainly love to hear the Berning. I could use a bit more power at times in my room. One thing is for certain, after having an OTL in the system there is no going back!
Chris, please keep us informed. I would love to hear your comments on this comparison. Thanks much.
I agree with you completely Will about sticking with the OTL sound once you have heard one with the right gear. I have never felt so strongly about any other amplifier I've owned or heard thus far as I feel about the ZH270. I'll bet the Joule's with the Merlins would be great indeed, I would like to hear that combo sometime.
I will report about our experiences in Chicago with the OTL's as soon as we return. It should be an audio day to remember, this is certain :)

I used to have 5.1's. Like I said, they dip to almost a short circuit in the critical midrange, and are VERY resistive in the bass. I've never understood why speaker designers do this kind of stuff. I played with OTLs before, but have moved on to low powered SETs and horns. I find DHT's to have much lower inherent distortion than any other amplification device ever made. Other designs get good measurements with negative feedback. Same goes for horns for speakers. I used to laugh at 'em, now I love 'em (with triodes).
Wow, great idea - using an autoformer to match impedance. I would guess that without these things, OTL's on the WATT Puppies would have a frequency response curve that looked horrible. Thanks for the post!
