Dedicated lines- need break in?


Surely a, stupid question of the day!
Finally had 2X 20 amp dedicated lines installed with Oyaide outlets with isolated grounds. Hooked up sources and preamp to the lines to start with......, and sound is much clearer and as a result slightly on thinner side (in comparison, although still anything but analytical). I know it is not Oyaide outlets because I had them connected on regular lines and they sounded warmer. (I have electrician coming back today to try out different phase than the refrigerator, ac, microwave etc. to check if the current in phase circuit breaker is not causing the change in sound)

So the question is, in your experience, the new 20 amp lines need to be broken in? How long does it need to be? or what could be the cause?

Thanks,

"The laws of physics are extrapolations from reality, not reality itself which is inevitably far more complex than the laws. The laws of mechanics don't predict that Stradivarius violins should sound better than modern violins either but few think they do not."

Bravo, Stan!

If I were you then I would not talk so fast. Because if you read what Stan wrote? He said I quote "A FEW THINK THEY DO" Meaning the sound of a Strad compared to a Modern violin how few and how many believe they sound better or just the same? My question is that time again when listener's are chosen to determine the sound of power cords and wire's connecting a System. They fail miserably to tell which is which,and that SIR is a real life experience .
Read clearly: "A FEW THINK THEY DO Not"!

As for power cord vs. dedicated line: apples and oranges; different subject for another time(not what the poster asking) .
I am in the camp that your new dedicated power lines will need some time to break in to sound there best. Nothing different than power cords.
Figure about 2-3 weeks at 24/7 .

I did not know how golden your ears were I stand at your alter..I am sure if a dedicated line were installed into your system with you knowing it and you fired it up you would have no idea until told. Then and only then would the famous placebo effect take place with jaw dropping sound..oh yes sweeten sound after a week or two breakin.
