**Cite your alleged "incontrovertible facts". I'll wait. I have copy of
RDH4. Just give me the page and chapter reference numbers.


-- a set of my opinions on matters of taste, without explaining how a
cultural taste can be a lie


**I have not argued with your opinions. Just your lies.


-- and so on into astounding subdivisions of irrationality and
stupidity


**Really? How about discussing your lies then? Let's see if you can manage
it, without profanity and insults. Just calmly and rationally discuss my
points, one by one. I bet you can't.


Let's take just one example of what Wilson declares a lie.


**No, let's discuss the entirety of my post.

I wrote:

"Let me say that again: after NFB, third and higher harmonics will make
up a
greater part of the distortion than before."


According to Wilson that is "a lie". Really?


**An half truth. You leave out the obvious fact that IF odd order distortion
is reduced to inaudibility (which it is in all competently designed amps),
then it is irrelevant what part of the distortion is even or odd. I said I
was addressing your lies and half truths.

It is in fact a fact
(heh-heh) agreed between all informed parties that the NFB, while
reducing the *total* amount of distortion, by its very nature alters
the frequency distribution of the remaining distortion so that the odd
and higher harmonics make up a greater proportion of the recombinant
residual. That is several times spelt out in my original article which
causes Wilson to foam at the mouth. So tell us, Trevor-baby, how is my
statement lie?


**It is a half truth.


I can't resist. Here's another statement (a rhetorical question,
actually) this blockhead Wilson singles out as "a lie":

"And they still use Negative Feedback?"


Uh, duh, Trevor-baby, are you now claiming that the entire audio world
has stopped using NFB? Amazing.


**Nope. It is a half truth. EVERYONE uses NFB. Every single amplifier
designer. Even you. By not spelling what type of NFB you are telling half
truths.


Below my signature I reprint Wilson's entire hysterical (and
hysterically funny) letter in full for connoisseurs of audio
fruitcakery.

What a blockhead.


**I note that you still cannot answer my questions. Not bad for a
"blockhead" huh? If you are so smart, then prove it, by demonstrating that
each and every one of my points is incorrect.

I'll wait.
