It is precisely the differences in approach and conclusion that

have their view.

As a further response to your comment I will say the following.

As computer technology has advanced, along with it the possibilities for
mathematical modelling of circuitry (which I have taken advantage of from
the very beginning), I have found that so doing has improved my
understanding
of and the performance of the circuitry I have designed beyond my wildest
dreams.

I don't doubt it for a moment. This makes the achievements of
people such as Williamson, Radford and Walker even more
remarkable. They used slide rules.

And the performaance of their circuits show it. They could have done so much
better with modern technology.

None of them are relevant to MODERN high-performance audio any more. They're
just a note in the references.
