Good power cord vs Killer power cord?

I have down sized some stuff in my rig and am wondering what to do. I am purchasing a brand spanking new Audio Magic Mini Digital that will be going into a dedicated outlet. It will be used just for my cdp. Got two power cords. One is very good, and one is drop dead amazing-(Harmonix Studio Master, case you're dying to know). Which do you put where? Dedicated outlet to AM?
AM to CDP?
My thinking is to go with the good cord directly from the outlet to the AM, and the killer cord from the AM to the cdp. I'd appreciate your experiences, as to what you have found that gives you electric nirvana. thanks guys. warren :)
