How does the sound change as power cables burn in?

The issue of cable burn-in and how many hours s required has been discussed here repeatedly. There is absolutely no way to know for sure what any amount of time may change for a cable unless you can do a direct comparison to another same exact cable that has not yet been used. And then many people would argue that you have "disturbed" the cable in the system such that such a comparison is then invalid.

I have done many rapid power cord swaps back and forth between different models (both with many hours on them) and the sonic signature of each is immediately apparent. And thus the point raised in the last sentence of the previous paragraph does not stand for me.

Rapid as in listen to 2-3 tracks and then jump to cord2 do the same, and then return to cord1. In a highly resolving system, significant differences can be heard between many pairs of power cords. Examples include NBS Statement vs. Kubala Sosna Emotion, Purist Dominus Ferox vs. Kubala Sosna Emotion, Stealth M5000 vs. Stealth Dream, Dream State Dream Catcher vs. Stealth Dream,

If this is questionable, that is your problem, not mine.

Liguy, you completely missed the point made by Glory. Glory did not dismiss that power cords can have an affect on sound. The point was that there was no difference from a cord right off the production line to how it will sound after it has been burned in.
