The moral of this tale is that if you want to make sure nobody can disagree
with you, just say stuff that is devoid of any meaning.

OK, Don. you are by your own admission a consultant and this is a thread about
valve amplifiers. What I propose is that you give me a selection of your own
valve amplifier circuit designs with your detailed construction notes which
prove that substituting componants has no effect on the sound. In return I will
give you a selection of my own valve amplifier circuit designs with my detailed
construction notes on the diverse effects of substituting componants. You are
welcome to breadboard my circuits with the relevant parts to check whether your
own ears confirm the effects I have found. That sounds reasonable doesn't it?
Let's put this to the test.
