Dedicated lines- need break in?

I cannot imagine that a dedicated line would need any break in period time. I know their are going to be people answering with jaw dropping sound quality that will come your way with a longer breakin period.

The mystery of the A/C sinewave.
I think equipment gets voiced with 'normal' junky power.. (big fat thick chaotic messy sinewaves.. then we come along and find ways to create smoth perfect sinewaves that the equipment does not respond well to. The 'thin' sound of smooth sinewave power.
I also have to wonder can power be made to be '"not too thick, not too thin, but just right."
From all the fooling around I have done with A/C conditioners I think it is hard to get the voicing of the A/C power just right, but it can be done.
My Forte' 4a amp with a 4 meter Pangea power cord is much better sounding straight from the wall. I am experimenting (Continuing!! to experiment) with the Monster conditioners and power cords to finess the ultimate sound effects of the power lines.

Yes, your new lines will have to break in. They will sound good right from the start, but will sweeten after a couple of weeks. It is hard to tell though, since it is usually hard to "switch" back to the old hook up system.

They will sound good right from the start, but will sweeten after a couple of weeks.

I am going to play Devils advocate and ask. Where in Kirchhoff's circuit laws do you find, after a couple of weeks "the sound will sweeten"?
