Do i need good pc s with PS PP?

I think power cords better than the typical OEM stock cords always help. You do not need to spend megabucks. Kind of like the cheap $1.00 interconnects that come with some equipment. They allow you to use the unit right out of the box, but should be replaced to really get the most out of the equipment.

A lot of people on Agon love the $60 Absolute cords. Some of my equipment came with heavy 14 AWG cords and they work pretty good. You can get them at any hardware store. I mostly have Vansevers standard cords.
