Best Budget power Cords

hi,you can build one if you want,save a lot of money but i dont think it make the sound better.

I am reasonably sure that a poorly shielded power cord can degrade the sound and/or create rfi problems. Beyond that I am not sure what you get when you start playing with different cords.
I have recently purchased 2 Volex 14 ga. cords from Newark Electronics for $35, including shipping and they seem to work fine. The changes, were, however only subtly for the better. These are the same cords that many diy'ers modify by changing the plugs.

Just put together some Asylum power cords from diycable.com and heard an improvement from stock cords in a headphone system. If you put them together yourself they're $38 for 4'or assembled for $63. In my speaker system I use Silver Audio Power Burst at $140 for 3'which definately made a difference. Both systems have PS audio power conditioning. I've never actually compared the two in the same system.
