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-induced distortion.
Semi-Solid Concentric Packed Conductors
Semi-Solid Concentric Packed Conductors are used in some of AudioQuest’s 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)
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.
The relationship between conductors defines a cable’s 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.
