All Rockville pro audio cables are made with 100% copper which boosts the efficiency of the cable. There is nothing better than 100% copper. Most of the cheaper cables on the market do not use 100% copper, instead they make their cables with CCA (Copper Clad Aluminum). CCA cables do not perform on the level that 100% copper cables perform at. Cca will not conduct signals efficiently. A 16 gauge 100% pure copper cable will perform better than thicker CCA cables on the market. If you find cables on the market that do not mention the copper content, there is a good chance that they are selling you a cheaper cable that is CCA and not 100% copper. Rockville pays an inspection company to oversee the manufacturing of the product to ensure that we provide a 100% Oxygen Free copper Cable (OFC). Our OFC cables are less prone to oxidation, and will provide maximum signal transfer.
