OTL Tube Amps-- are they superior to everything?

Trelja, you did mention OTL to me and I know that you own OTL, and you did provide me with some food for thought there. But you were not the Audiogoner I was referring to. You don't own Atma-spheres, which at the start of this thread, I mentioned were the amps this Audiogoner owned.

This is just a clarification, not meant to take away from your appreciated and insightful comments. Thanks again for the generous sharing of your experience and knowledge.

The Berning sounds very interesting, although I would be concerned about the complexity of the design and its execution, plus the fact that I believe Berning disappears and reemerges periodically. Correct me if I'm wrong.

One thing I forgot to say in all of my BS is that sometimes, I prefer the sound of my Jadis amp over the Atma Spheres. It all depends...

Trelja, are you referring to Paul Speltz ZERO autoformers? If so have you ever tried the alternative 2X configuration? I found this configuration was more nuanced than the standard configuration. There was a slight drop off in bass output though. I then used two pairs, alternative 2X on the high frequencies, and standard 2X on the low frequencies. This yielded absolutely phenomenal results on the N.E.A.R. 50Me II speakers I was using at the time. I would love to hear about your results if you happen to try this.

Saxo, as a multiple Berning owner, I can only agree with what tubegroover and TWL said regarding its abilities and advantages.
However, I'm not quite sure what you mean by the amp 'appearing and disappearing'. If you mean availability of the amp to buy used here on Audiogon, they certainly are less commonly available used than more mainstream products, but that does not mean that there is something 'wrong' with them. There was one available a week or so ago here; it isn't there now, but that's probably because when they come up, they sell fairly quickly. Actually, I was thinking of buying it myself to compare a 'solo' 270 to my monoblocked ones, but common sense reared its ugly head. Both of my Bernings were bought through ads I first saw here on Audiogon, in fact.

OTL, means output transformer-less device, does not mean "nothing between the plate and speaker terminal", then it would be NPST or something like that, some OTL designs may use caps or resistors in between the plate and terminal, in fact some highly regarded units may do so.

The ZH-270 is an "OTL" amp in every respect of other "OTL" amps, just that it does it in a very high technology way, or different than anyone else.
