I enclose the following, from Geoff Mead (Audiocircle): does anybody
know anything about this? Quote goes:

Re the current thread on speaker cables and sonic differences between
different amp/cable/speaker combinations. There has been an
interesting series of articles in Electronics World staritng June
2004 if anyone hasnt seen them. The author Graham Maynard started
looking at the old chestnut as to why valve amps sound different from
S/S ones particularly when played loud.

It might be more to the point to explain why tubed amps have this nasty
tendency to change how they sound when you hook different speakers to them,
even more so than that which can be explained by the sonic differences
between the speakers.

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.
