You can use any aftermarket grounded power cord since the ground pin is floated at the Blue Ray chassis. At the wall the ground pin will help hold male plug in place.
I have the Pioneer Elite Blue Ray and tried several cords, all help the sound a little but I would not claim it's a good value to buy ultra expensive AC for Blue Ray as it behaves more like a computer than a high end CD player.
