Audiofeil, no, no, no. Every power cord sounds the same, it's the wall socket that makes the difference. :-)
Below is a scene I'm writing from "A Few Good Audiophiles". (Any similarities to "A Few Good Men" is purely intentional).
Jack: You want the proof?
Tom: I want the proof!
Jack: You want the proof? You can't handle the proof!
Jack: Son, we live in a very electrical world. There are things that go on that you can't possibly fathom. I offer the security of a well made wall socket so that you can sleep at night under the blanket of knowing that you are getting the best sound possible. Deep down, you WANT that socket in your wall. You NEED that socket in your wall and I resent you even questioning my authority about the way I go about it.
Jack: Are we clear?
Tom: Crystal.
