Well, your SET might be able to bypass fundamentals from 2hz to 35khz but unfortunately it is all the OTLs are good for as they severally skew up harmonics, making Sound more like a “frequency pushing” instead of music. Ironically, despite that you suggest that your SET is not sensitive to load some people, among those who make OTL to sound more or less acceptable, change of the OTL loading giving with OTL very high impedance (sometimes >50R). Anyhow, sometimes do for yourself an experiment: find a good 1:1 transformer and juts bring your signal though a transformer core you will see were the SET sound is born….
At any rate, with all my experience with OTL amplifiers, and I have see quite many of them, I do not recognize them as anything SET related, though they certainly topologically might be SETs. The OTL are own unique animals, very intellectually elegant but hardly functional for Sound (unless you drive some strange electrostats or railway track suspended in magnetic fields….)
