Phono pre "Break-In" process? Necessary?

Just ordered a new phono preamp from Jolida  (J9II). Is there a break in process I should be aware of? Or do I simply play normal and realistically believe that it will open up as time goes on. Also, how much can one expect this pre will improve over time?

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.

Thom Mackris, Check out my post (seventh post in, on a two page thread) I realize it is a long read and life is short, but geez... really?

cleeds,

I'm sorry for the confusion. I may not have properly explained this phenomenon. Its all in the viewpoint. I have more experience in the field of distortion than anyone. (Bold statement? Yes) Its because I have studied in great detail what happens to a signal as it passes through an amplifier circuit. A good 30 years of research just on this one aspect of amplification.
It has been my goal to find any error whatsoever and deal with it in real time. For that reason the technology I am using is years ahead of any other attempt at analog amplification. There are no man made tools available to show what has been going on. That's why it is pure theory.

This is why I am able to claim the complete removal of distortion.
The effect of having no distortion is like nothing ever heard by audiophiles.
The reaction of those who are exposed to this is unanimous. Shock followed by great joy in what they hear.

I might add that I am quite humbled by what I have discovered and thank God for his help.

Everything I post is fact - with hard evidence to back it up.

I am in the process of responding to wolf's comments and will take one statement at a time to explain what happens electronically vs what happens acoustically.

The mystery is gone and I am trying to share my findings with audiophiles who are the first to take advantage of this body of work. Poking fun at a process because it is not understood is not helping anyone.

The reason it sounds odd to describe what you think is your understanding of distortion is because there has been new information revealed that explains the missing links between what seems to be a straight forward process and one that actually encompasses the total process including errors the have gone unnoticed. (Not found in the text books - sorry)
The amplifying process was never taken to its limit. I took it there.

The confusion is not on my end.

BTW - "what you think" (I'm not referring to you cleeds)

Roger
