What is Oxygen Free Copper vs. Standard Copper Speaker Wire?
There are numerous materials used to build speaker cables from copper to oxygen-free copper (OFC) to silver. There is not a significant difference in sound quality between speaker cables made with Oxygen-free copper and speaker cables made with standard copper. The difference is oxygen-free copper prevents corrosion which over time will deteriorate the cable and eventually lower conductivity. So the better the materials used to build the speaker wire the longer you will have great quality sound performance.
