AudioQuest X2 Unterminated Speaker Cable
The X-2 is a 14 awg speaker cable which uses semi-solid concentric-packed long-grain copper.
In a conventional multi-strand cable, distortion caused by electrical and magnetic strand interaction are compounded as each strand changes position within the bundle. In an Audioquest Semi-Solid Concentric-Packed cable, strands within the bundle maintain their fixed, rigid relationships, significantly reducing distortion.
This copper is considered "Oxygen-Free Copper." What this means is that the copper is actually oxygen-reduced, but is not selected for low distortion. AudioQuest's Long-Grain Copper means fewer impurities, less grain junctions, and lower distortion.
