If the power cord does not have a voltage drop, has good shielding and also good high frequency characteristics, its sound quality will be as good as a much more expensive cord with the same characteristics.
Power cords are not actually voodoo, but there is a surprisingly large and totally unnecessary snake oil. I suspect this is because many of the power cord manufacturers simply don't know why their cable works.
