Best OTL speakers

My favorite speaker with an OTL are Kharma's, high effeciency and high enough impedance on most of there models.

Sound Lab electrostatics. These present the higher impedance load that OTL's crave without the dips characteristic of dynamic speakers with fancy crossover mechanisms. For 4 ohm or other dynamic speakers with impedance fluctuations below 6'ish ohms, the use of an autotransformer (Paul Speltz Zero, Atmasphere's own or equal)is highly recommended - no, its mandatory!

"fancy crossover mechanisms" won't create impedance or reactance problems if they are competently engineered.

That said, I have NYAL OTL-4 here, and it loves 8 ohm speakers, impedances that drops below 6 are will tend to constrict the amplifiers power.

The Butler OTL will drive any load, and sond like a million. I have heard it on Cabasse Kharmas and it was sensational.

These are a MUST audio, a nearly perfect speaker. IMO
