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.
