Phono pre "Break-In" process? Necessary?

wolf_garcia,

As a product accumulates burn-in time the distortion is reduced.
If your system begins to sound worse - Don't blame the new product, blame a component ahead if it that may have sounded harsh but was tamed down by the "fresh" amp that could not yet pass fine detail. When that amp finally achieves zen it simply exposes the quality of whatever is driving it.

GIGO.

Show me someone who doesn't believe in break in time and I will show you someone who has never owned Morrow cables.

At 4:20 this thread appeared to run astray of any reasonable logic... could it just be a Friday "burn-in" gone up in smoke in someone's time zone?

Yes, components take time to break in.  Capacitors and their various resonances are a good example.  Different capacitors take differing times to form.  Different TYPES of capacitors take different amounts of time to form.  And most other components take time to form their various capacitances even if it is a simple resistor mounted to a circuit board (the board itself can act as a capacitor).  And as those capacitors form, it changes their resonances.  Resonances contribute HEAVILY to the sound of a component.

That's JUST the beginning.

BP,

Please google  "Capacitor Forming"  then comment.

Good listening
