Have too? No.So HaveMeterWillTravel's statement about eliminating this "mains phase inversion induced common mode noise" by using a different power cord actually means you have to modify a power cord by cutting it open and swapping the hot and neutral wires?
I would never advocate doing this. One is now risking a house fire.I'm going to show off the depth of my understanding of basic electrical theory by asking another question: instead of cutting open the ac cord and swapping the wires, wouldn't it make more sense to pull the wall receptacle out and swap the wires there?
If that actually fixes this problem HaveMeterWillTravel has identified, wouldn't it make OP's assertion "an AC Power Cord cannot make a difference" strictly true - assuming your ac wall outlet is wired correctly?
It is not an issue of the outlet nor the cable being incorrect, per say. They most likely are. Rather, if there is an issue in the equipment, then it may be the most practical method for an end user.
Myself? I just pitch the power supply and get a correct one.
