This is a single cable, not a pair. This double star quad geometry ‚Flat Rock‚ cable does not look normal on the outside, and it is not at all normal on the inside. A sophisticated combination of extraordinary materials and extremely refined design lets the Rockets equally honor all types of music. Solid Conductors: Eliminate harshness and confusion due to strand interaction. Long-Grain Copper/Perfect-Surface Copper: Rocket 33 uses a carefully finessed combination of Long-Grain Copper (LGC) and extremely high-purity Perfect-Surface Copper (PSC). LGC has fewer oxides within the conducting material, less impurities, less grain boundaries and definitively better performance. The astonishingly smooth and pure PSC further eliminates harshness and greatly increases clarity. Dual-Triple Geometry: The relationship between conductors defines a cables most basic electrical values (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 affect the sound. The Dual-Triple construction of Rocket 33 allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel. Spread-Spectrum Technology (SST): Any single size or shape of conductor has a specific distortion profile. Even though radially symmetrical conductors (solid or tubular) have the fewest discontinuities, any particular size does have a sonic signature. SST is a method for significantly reducing the awareness of these character flaws by using a precise combination of different size conductors. The six different SST-determined conductor sizes used in Rocket 33 allow an exceptionally clear, clean and dynamic sound. Bi-Wiring: Rocket 33 is an exceptional Single-Biwire cable.
