Dedicated lines- need break in?

I think Rwwear sums it up in a nutsheel..

Well, Schipo, the devi's advocate, (which I enjoy playing too from time to time.) I really didn't want to define all the ways the above system could improve over a couple of weeks. But from lots of experience with this phenomena with my own personal systems and with several friends systems, I know that it happens. I used the word "sweeten" not in a sugary sense but that things would get better as the cables/wire/outlets/components all broke in. (I've helped friends (besides myself) run the wiring and I heard what their systems sounded like both before dedicated lines, then the same afternoon the dedicated lines were run, and a couple of weeks later after the outlets and wiring "broke" in.) I can only state that I'm not used to embellishing the truth of my audio experiences and the results were quite worth the bother of running the extra lines across my friend's and my own basements to enhance our systems. In fact, so worthwhile have I found it in my own system, every piece of audio equipment I own has its own dedicated line. I think I'm up to about 25 lines now. I'm sure the above system will sound "sweet" when everything has settled for a couple of weeks.
If you have never tried it yourself, don't knock it. However I can readily understand other's scepticism as to the effect of "breaking in" wire or other components. I just know it does occur,(and have at least 30 years of experience to back it up) and like many others who have posted after me, would not make any other changes until the system has settled in.

Some things just aren't true no matter how much you want it to be.

From a closed mind comes nothing new no matter how much that mind wishes to believe it knows all. The closed mind can only parrot what it has been taught. Is it any wonder then that the closed mind eschews original exploration that could lead to self discovery and knowledge in favor of the same old staid and tired theories; the observations of others?

Do you mean connected to an earth ground other than the main earth ground of the main electrical service? "

No It is connected to same ground at the panel. The electrician said isolated means isolated from other grounds down stream of main panel.

The phase change did make the lines ultra quiet. Among few pluses to the sound at first listen: Increased liveliness, dynamics and jump factor, minimum grain, more focus. Minuses: slightly smaller images, less warmer than before (I had almost zero unnatural highs)

Well, Thanks for all the responses. Both for break-in and not. Thanks for the fun guys. Like I said I expected this to be considered by many a stupid question of the day ;-) I researched the archive and did not find anything about dedicated power lines break-in so I thought worth asking your experiences. Of course, I tend to believe credible answers are the ones from those who have dedicated lines installed and went thru 'learning/listening" experiences first hand.

I do believe in cable break-in (for reasonable amount of time) and thought the brand new wires probably need run in time.

Oh well, I still have my 15 amp regular outlets to fall back to get my original perfect sound back. I will let new lines burn in though for a week or so, just to find out (for $$$ total costat least I should give it a try- those Oyaide outlets and front machined Alum plate ain't cheap , nor the lines install cost)

I will report back.

Keep the responses coming. Happy New year to all.
