From a man who will not / can not even measure the performance of his
own design

Let me repeat for the nth time where n is a large number that I have nothing
against engineering whatsoever, and I go out of my way to have my amps measured
on scopes and distortion meters.

As for "up-to-date" and valve technology

Yes, that's exactly what I said. Check posts on audio Asylum.

I presume that means that ECC83s, 12AT7s, EL43s and the like are
not to be found in your designs?

Correct. I've already given a list of valves that sound better. If you want
references:

And of course transformers no longer
have hysteresis losses and non-linearities?
And ss amps still use elecrolytics in the sugnal path.
