While I absolutely agree that the vast majority of claims for power cords are absolute nonsense, when I brought home my Marchall amp for the first time there was a loud oscillating hum. Back to Guitar Center it went, where we couldn't duplicate the problem. They gave me another one anyway, and it had the same problem.
Ultimately we found that I had a wall wart power supply in close proximity to the power cord, and moving them far away cured the problem.
Just be sure your cord has good EMI/RFI (anything reasonably well shielded) and your good to go.
Or get one of those $4,500 "soundstaging champs" for a real guitar amp epiphany. Sure
