These cables come from the installer series of AudioQuest and are packaged in plain Mylar bags. Don't expect the fancy packaging that you typically find with other AudioQuest products. NRG-Y3 cables use direction-controlled Long-Grain-Copper (LGC) strands in a Semi-Solid Concentric conductor arrangement in which strands are packed more tightly and never change position within the bundle. This construction significantly reduces strand interaction distortion. The greater purity and less complicated grain structure within LGC copper further reduces distortion.
