roger_paul " ... Actually - it cannot be measured by external analyzers but it can be detected within the circuit and removed."
If you have identified distortion but can't measure it, then either you are measuring the wrong thing, or you're mistaken about the distortion in the first place. If the distortion can be "detected," then it can be measured.

roger_paul " ... Yes there is distortion that cannot be
measured and has been the most destructive obstacle in the way of
reproducing actual live sound ..."
If you have identified distortion that you can't measure, then you are measuring the wrong thing.

r_f_sayle " ...Perhaps whatever we hear is all that matters.
I do not derive any pleasure from numbers, or being 'right'.
Your
statement is most accurate, yet if I'm musically fooled and happy (in
front of my Hi-fi), is it not a better place to be than scientifically
baffled and frustrated and somehow not into the music?"
Oh, we agree completely! For me, the music is more important than the numbers. I'm grateful that we have audio engineers who do most of the work for us! All we have to do is assemble the components, tweak and listen.
What I was responding to was the claim by roger_paul that he had detected some form of distortion that cannot be measured. That's just a silly claim. Almost by definition, if it can be reliably detected, it can be measured.

r_f_sayles " ... never the less, we hear without fail."
Oh no, you're mistaken . The ear is very easily fooled. |
roger_paul " ... THD
analyzers do not detect velocity. It is too far below the ability to
display. The circuit can detect velocity and correct faint variations in
speed in real time."
Oh, you are talking about a turntable! Speed variations can certainly be very precisely measured. Indeed, the speed of anything can be measured. You just need the right tool.
|
roger_paul " ... in
order to have speed variations on the turntable the are like those found
in amplifier, your TT speed (33 rpm) would have to speed up to 66 rpm
in order to produce a harmonic of what ever is in the groove.
Amplifiers
that can generate energy at 2 Khz from a 1Khz fundamental experience a
very rapid change in velocity causing the fundamental to "slide" up the
spectrum and be seen at 2khz and then slide" back to 1Khz.
If it does not slide - then it is digital not analog"
You sound very, very confused. Good luck to you in sorting it all out.
