Here is something interesting I discovered about OFC hifi cables.

There are 3 mains type,

C10100 - also known as Oxygen-Free Electronic (OFE) This is a 99.99%pure copper with 0.0005% oxygen content.

C10200 - also known as Oxygen-Free (OF) It has a 0.001% oxygen content, 99.95% purity

C11000 - also known as Electrolytic-Tough-Pitch (ETP) 99.9% pure. It has 0.02% to 0.04% oxygen

Standard C11000 wire thats is in your house wiring, electrconic products and has the same electrical resistance as the OFC type of 1.71 microhm-cm @ 20 C. OFC copper is used in high temperature applications such as high power generators. The link show the properties for each of the copper type.

So standard copper cable is as good as OFC copper cable in transmitting the electrcial signal despite what cable companies tell you.
