I know about the transformers much less then you might imagine. I know if they work of not but why they do or do not do so I have no idea. Some people believe that they do know, I feel that many of then have in fact no really idea as well. Transformer is really the “terra incognita” of audio, at least for me….

Anyhow…

Regarding the OTL, although it is a lightly a different subject I detected that if we have an abstract OTL amp then a relative performance of this OTL will wary with the impedance and sensitively of speakers. However, it is not only about the ability or disability to work against complex impedance but rather the dynamic-harmonic characteristics of sound that become radically different since the speakers damp/react to the OTL (or OTL react to them) I think if to have I would say 4-5 ways high sensitively and high transient response installation and to be able to leverage impedance of EACH channel assuring the a given OTL produce the same harmonic structure within the widest dynamic range and within the same frequency range then it would be possible to make an OTL to perform correctly. Meanwhile an OTL driving a full-range conventional loudspeaker never perform well unless it drive a slow and dead loudspeaker of high-flat impedance and with sensitively of 75dB
