These distortions CAN be measured and HAVE been measured numerous
times. Measuring voltage and current is not really that hard. Where does
your distrust in test equipment come from?


Because it's not perfect. Where does your distrust in ears come from?
Besides, if you're saying it's been measured, that just proves my original
point.


You never answered the question. I have no distrust in my ears, but I do
know ears limitations. And I fail to see how it proves your original point.


My original point - if you had been in the discussion all along rather than
jumping in with your tired old preconceptions about audio "mysteries" and
"magic" - was that differences in amplifiers can be measured. MZ said they can
not because there aren't any. Now he's backpedaling. ALL amplifiers - ALL -
exhibit distortion. The only question is whether test equipment is precise and
accurate enough to measure this distortion. That's unlikely in all cases, since
perfect test equipment does not exist any more than perfect amplifiers exist.


The point I made is that any distortions that are present have been and can
be measured and in a properly functioning amp the differences in signal are
below the human threshold of hearing. How does that line up with your
original point.


The differences were not below my threshold of hearing in one of the tests I
conducted. You can believe that's possible, or you can stick your head in the
sand and toe the party line.

I've been paying attention. That is basically the 2 options. Since you seem
to have something against test equipment and believe it is not accurate
enough to measure some component that gives an amp a sonic signature, then
you must think there is an immeasureable (at least for now) compenent that
can be created with accuracy yet has no way to be measured.


I have nothing at all against test equipment, which just proves you really
haven't been paying attention.

Obviously to subscribe to the philosophy that amps have signatures then
logically their designers and makers would be able to know how to give them
their sonic characteristics, right?


No, that is not necessarily a logical conclusion. People design amps the way
they design them. Each one sounds different at some level of accuracy of
measurement. Whether or not in each particular case it's below the threshold of
human hearing is the only question. I gave one example where it was not below
the threshold of my hearing (I happen to have better hearing than most people,
which explains why I sometimes hear differences in speakers etc that some others
can't notice.) Presumably, the difference I heard can be measured by test
equipment. If the test equipment cannot detect a difference that I can hear,
then obviously the test equipment is flawed or not precise enough.
