Tubegroover, it is an OTL, it's just a new type of OTL, as a Glass audio reviewer puts it, a unique approach to the output transformerless problem. The word unique, being very understated :)
As far as the audio signal is concern, there is nothing between the tube and the speaker terminal. That is what makes it so unique :)
So yes, debating whether it's the terminology or the actuality that makes it an OTL, or not, will never cease, that is of course until the patent runs out and others can copy it.
