OTL amps on Dynamic Speakers

i might recommend the Atmasphere line as one of the the best and most stable OTLs with dynamic speakers. the M-60, MA-1, and MA-2 are all solid and excellent performing.

i used the MA-2 MKII.2 to good result on the very difficult to drive Wilson Watt/Puppy 6s. many less powerfull atmasphere amps are used with numerous dynamic speakers.

personally i own and also recommend Tenor Audio 75Wi monoblocks, an integrated OTL amplifier that i prefer if your speakers are a stable load and 90db or better efficient.

While I was not aware of the Jadis being an OTL, the Fournier is a wonderful sounding amp. Others that would do the job quite well are the Atma-sphere MA2's and the higher powered Joule Electra's.

I drove the Wilson MAXX's (92db) quite well with both the Atma-sphere's as well as the lower powered Tenor's. The MAXX's are deceptively tough to drive, complex crossover as well as a 13" and 10" woofer.

The OTL's were much more extended and natural in the highs and also sounded much quicker than the transformer based amplifiers I have had.

Go for it!

I am driving Audio Physic Avanti III's (89db, benign 4ohm load) with the Tenor 75w OTL's and it is the best sound I have ever had. My room is 15x25x11h. Hope this gives you some reference.
