How does the sound change as power cables burn in?

Whenever I have gotten a new power cord I just put it on a piece of equipment that will pass current through it for 240 hours or so and then install it in my system and listen. The sound of my system with the power cable in place is what it is.

I know I have no baseline to compare what the cord sounded like before and after burn-in but my reasoning for doing this is that pretty much every burn in thread I've come across has stated aftermarket cables change/improve the SQ of your component after 200 hours or so of break in. To me why go through the trouble of the swapping back and forth and wondering. Just run the cable in and listen.

Some cables, usually excellent ones, continue improving after 200 hours but not dramatically. And not only power cords.

I would have to agree with Glory. I can understand an interconnect having an effect on sound but not a power cord. I am all for having a good quality power cord so it can deliver the proper amount of current but because it is before the power supply I just can't see how burn-in has any effect at all on a power cord.

Can you understand how a Bumblebee flies? It's an aerodynamic impossiblility. There are quite a few things that work in this world, that no one actually has a concrete answer for, YET! One thing I DO know; Any improvements to the power supply of a piece of audio gear(and/or the power to it), can provide great sonic benefit.

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.
