Seasoning your sound with powercords

Do you season your components with opposing sounding powercords?

For instance, if your dac is neutral would you put a warmer sounding powercord on it?  And if you have a warmer sounding amp would you put a leaner sounding powercord on that?

I have a 10 gauge gold series cullen cable and a 12 gauge crossover series powercord.  I would think that it would be better to use the 10 gauge gold cable on my integrated and the 12 gauge crossover series on my gungir dac, but I believe that Patrick recommended doing the opposite.

I feel like I have lost some top end on my new Carreras compared to the ones I did a review on but I made like 3 other changes at the same time.  I replaced the crossover series on my integrated with a brand new gold series, added a gungir dac instead of the bluesound dac, put the crossover series on the dac, and I believe that all the drivers and crossover components on my carreras are brand new.  I’ve let me system “run in” for maybe around 12 hours now.  I also had to twist and bend the gold series powercord quite a bit right out of the box to get it positioned the way I want it.

With all this in mind, I feel like the top end on the Carreras is less pronounced than when I was reviewing a different pair 2 months ago, on the bluesound dac...

Any thoughts?
