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.
