Large complex output impedance ?

Makes for an interesting potential divider effect.


To cut a long story short he
proposes that Miller compensation and series output inductors are
responsible in causing what he calls First Cycle Distortion.

If this purported distortion existed it would be easy to measure. Did he
show any measurements showing that it actually exists?

Let me guess - he wasn't able to mesure it, but instead provided a lengthy,
hand-wavy theory of questionable merit.

It sounds like total hogwash to me but probably likely to provide a great
source of aftermarket add-ons.
