Power cord replacement where first?

Like Eliz says, try it on both. Let us know your thoughts.

Thanks for the input I do not have the Kimber pc yet but, also looking at zu, audio art. Anything I can find under 100 dollars really. But I never thought of experimenting after I purchase it haha. Good thought . I also haven't changed speaker cable. I guess I should look into that as well. Basically I want to improve my system by adding to what I already have before considering changing existing which I really don't want to do

I still have monster xp speaker cables. Maybe I should replace them first?

I'm surprised nobody suggested upgrading your power to your wall outlets first. Dedicated 20amp lines for amps and source will make a much bigger improvement than power cords.

Upgrade all cords with Pangea and call it a day, for less money. I was very impressed.
Glad to hear things might get even better with a dedicated 20 amp line.
