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,

Your system won't draw more power because it's on a 20amp circuit. It will only use what it needs. If it needed more it would trip the breaker on the 15amp service.
Excellent idea Musicslug! Now to decide what piece of music the OP will use.
I do not care to argue or debate with anyone.
I’m simply going to answer Nilthepill’s question based upon my opinion that comes from trial and error and my own experimentation. Readers can believe what ever they want.
Yes, AC lines need time to break-in and should sound better or different with use but I don’t know the scientific reason why.
The AC wire you use is directional and I tested my wire (out of the wall first) for which direction sounded best.
Different brands of AC wire can / might cause your equipment to sound slightly different. The same holds true for wire gauge.
Putting your circuit breakers on a different phase could help improve your situation.
For AC power break-in I have found that 7 to10 days of 24/7 usually does the trick. Even running an electric fan from the outlets using the two different circuits when not listening to your system will work.
