No matter how perfect an AC power source, distortion is added within any AC cable, especially within a stranded cable. Even the most sophisticated filters and power supplies cannot eliminate this cable caused distortion. Because having the right tools for the jobs can often be unpredictable AudioQuest offers NRG-X3/i in packs of 5 in the following lengths: 8", 16", 24", and 36".
SEMI-SOLID CONCENTRIC PACKED CONDUCTORS: Semi-Solid Concentric Packed Conductors are used in some of AudioQuests AC power and speaker cables as a cost-effective, flexible alternative to typical stranded conductors. Semi-Solid Concentric Packed Conductors use fewer, larger strands that do not change position down the length of the cable. While solid conductors are the complete solution to strand distortion, Semi-Solid Concentric Packed Conductors avoid many of the distortion mechanisms of stranded conductors.
LONG-GRAIN COPPER (LGC): allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metal industry specification regarding loss, without any concern for distortion. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance. NRG-X cables use Long-Grain Copper (LGC) strands in Semi-Solid Concentric Packed conductors. This physical arrangement, in which strands are packed more tightly and never change position within the bundle, significantly reduces strand interaction distortion. The greater purity and less complicated grain structure within LGC copper further reduces distortion, as does the helical relationship between the conductors. Using these finely finessed cables enables a more engaging, more enjoyable, more effective experience.
HELICAL-ARRAY GEOMETRY: The relationship between conductors defines a cables most basic electrical values (including capacitance and inductance). However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly effect performance. Helical-Array (such as circular-spiral) construction allows for significantly better dynamic contrast and clarity than if the same conductors were run in parallel or as multiple twisted pairs
TERMINATIONS: The connection between the plug and conductors is made using AQ's Cold-Weld system which provides a superior connection that ensures that the structural integrity of the conductor is kept completely intact. The Cold-Weld system refers to a combination of high pressure at the point of contact and the use of copper or silver impregnated paste.
