@crutschow (and @rpschultz as it was mentioned on your thread). I've now fully recovered after a week in hospital with a bacterial lung infection and after four weeks of antibiotics, I have 82 test results that prove I'm OK now.
So as I now have access to my computer which runs SPICE, here is, as promised, the amplifier that SPICE claims manages 3ppm (-111dB) third harmonic distortion. There are two circuits, almost identical except for the VAS stage, all with very similar figures for each harmonic, but SPICE says that TOTAL harmonic distortion is four times as good for one as the other.
And as I said previously, I really don't see how either of these circuit could possible be as good as it thinks they can.
