Good discourse going on here by two of the audio paragons. For what it's worth, the opinion of the village idiot...
I am the owner of a pair of AtmaSphere M60 OTLs, and have also had the pleasure of being around a Berning ZOTL just over one month ago.
While I will not get into the circuit designs of either, as I have not immersed myself in them. I don't know what is and what is not this or that. I will say that I was more than a bit surprised to find out exactly just how similar both amplifiers sound to each other. And, in the end, is it not really the sound? However close or not the designs are, I have NEVER encountered an amp that sounded so much like my Atmas as the Berning.
