The funny thing about this is that no-one has been able to build a DH triode amplifier that actually sounds better, although I have heard plenty that that are very musical. None of them so far has expressed lower distortion when running open loop, nor do any of them have any serious bandwidth. These are the sort of things that translate to audible as well as measurable (meaning they are real). By lowering distortion one makes low level detail more available as distortion masks detail. The is one thing OTLs excel at against nearly all comers (certainly SETs and push-pull tube amplifiers) and is one thing that over the years 6AS7G-based OTLs have gained a reputation for.
It may be that on paper DH triodes are more linear, but the performance is locked up where no-one can use it: on the other side of an OPT winding. In a sense that was part of what the 300b OTL was about: to see what possibilities existed.
So what is, is that the linearity of 300bs and 6AS7Gs, real or imagined, is of no consequence.
I accept your apology; you did not mention what question I had not answered.
