The regular power cord is a copper 14/3, which is actually from Taiwan. Surprise, surprise. We buy them in quantities of 500, so the price is good. I listened to maybe 8 or 9 a few years back, and this standard one is simply quite good.
Now, every pc will make a difference, I just can't state absolutely if this is a step forward or backwards, if it is a small step or a big leap. There are so many variables involved here.
HOWEVER ::::: for our customers, we have special deals on Quattro P/C's, for $ 75. And thaht cord works well no matter what system.
