OTL amplifiers

I have owned 2 OTL amps, and still own one of them. The ones I have had have been just as reliable and easy to use as any solid state amplifier I ever had. Absolutely no fuss whatsoever. But the sound is better than any other amp I've had by far. I see no reason to avoid OTL for reliability reasons anymore. That is simply a part of their early history, and has no impact on the current crop of OTL amps. I have the Berning ZOTL-type, and I think it may be the best design of all amps ever. And if you want a SET OTL, then it is the ONLY choice possible, because nobody else can make a SET OTL, except Berning.

Yes, I'm referring to single tube SET, with my statements. All others are simply parallel configuration to lower output impedance. As Albert Porter once described it to me, parallel is like a choir singing, and single tube is like a soloist singing. No matter how syncronized a choir sings, it will never be as clear and articulated as a soloist. I thought that was a very lucid description. I think the simpler the better, as long as it can get the job done. Of course, there are certain speaker requirements for efficiency in order to use low power single output tube SET amps.
