In a conventional multi-strand cable, distortion caused by electrical and magnetic strand interaction is compounded as each strand changes position within the bundle. In an AQ Semi-Solid Concentric cable, strands within the bundle maintain their fixed relationships, significantly reducing distortion. Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.
