Phono pre "Break-In" process? Necessary?

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.

It is those speed variations the destroy the integrity of the final output sound and make objects embedded in the signal appear to be drifting (not stable).

In defense of the theory of "detecting the immeasurable". We have heard for decades, perhaps since the beginnings of mankind, certainly before electronics, things with our highly tuned listening devices, things that if our ancient ancestors had not heard and understood in time/space/direction cues, we would not be sitting in front of our glorious Hi-fi kits today for a casual listen. And so it goes, scientists still can't put simple numbers and logic to what we sit down with. Our old, damaged, ears and faulty logic, but sessioned listening skills and never the less, we hear without fail.

Two violin players play the same piece, note for note, why does Heifetz not sound like Grappelli?

Happy Listening! (regardless of measure)

cleeds,

I hear without fail.

That doesn't mean, I hear perfectly or understand perfectly (scientifically) what I hear.

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?

Thank you Zen master Hakuin for the koan, what is the sound of one hand (clapping)?

Happy Listening!
