Unless the original is damaged, I cannot see where it would make a diffference....If it does make a difference on a given component, I would not buy that brand, since they would have clearly demonstrated their negligence in not providing a suitable cord, which is unforgiveable for such a basic item.....and if the original power cord disturbs you, dont look inside the case of your amp....you will see all those skinny little cheap wires that look like those in a 1960s transistor radio, and be compelled to replace them also since they carry current and signals..
