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,

Cables should have been connected to a cable baker and ran 24/7 for 1 week then gently massaged with magic sound inforcer and then sprayed with Mapleshade EMI/RFI line reducer then coiled and recoiled to line up the electrons to north/south bias they are directional you know, (follow the arrows)and then the ends should be treated with sonic connector juice and an audiophile silver treatment only then installed and calibrated by a ISF electrical professional while listening to a "cable-burn-in" enhancement CD or Tchaikovsky's 1812 Overture for a dynamic installation:) I'd say give it 2 weeks to get broken in... if no improvement start over and run wire the other direction;)
I see as per usual some who profess that no difference exists between cables are again entering into a discussion regarding the "subjective" difference between cables (in this case cables running in-wall). Surprise surprise the ones who hear no difference in wires hear no difference in dedicated circuit break-in.

Yes dedicated circuits break in and over a several week period. I usually wait at least one month to allow any change in my system to settle down before making another change or before fine tuning my last change. This allows time to reflect, prevents costly mistakes by not addressing a still moving target, and to enjoy my system instead of constant fussing and that's a good thing :)
After getting 2 dedicated 15a lines I will admit after 100 hrs they sounded much better and at 200 hrs really good. I didn't get 20a for I do not want much more power draw than I already have. I also added a 2.4 kva balanced isolation transformer to 1 line. Just a little better than with out it. Can't figure out why but to some degree it's similar to speaker cables - ic's and power cords I guess. That has been my personal experience.
