Jacket: black/green/gray braid Rocket 88 incorporates AudioQuest's patented Dielectric-Bias System (DBS) and replaces Long-Grain Copper with Perfect-Surface Copper+. DBS offers a lower noise-floor, so you can hear deeper into the nuances of your favorite music. At the same time the addition of more PSC+ offers a smoother, more relaxed, and natural sonic timbre and texture. SOLID PERFECT-SURFACE COPPER/PERFECT-SURFACE COPPER+ (PSC/PSC+) CONDUCTORS: Rocket 88 uses a carefully finessed and optimized combination of Perfect-Surface Copper and extremely high-purity Perfect-Surface Copper+. The astonishingly smooth and pure combination of PSC+ and PSC significantly eliminates harshness and greatly increases clarity. Rocket 88's conductor mix is dominated by PSC+. CARBON-BASED NOISE-DISSIPATION (INSULATION): The four negative conductors in Rocket 88 are insulated with partially conductive Carbon-Loaded Polyethylene. This remarkable material damps radio-frequency from being fed back into the amplifier. Rocket 88 uses Foamed-Polyethylene Insulation on its positive conductors. DIELECTRIC-BIAS SYSTEM (DBS, US Pat #s 7,126,055 & 7,872,195 B1): All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio. AudioQuest's DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. SPREAD-SPECTRUM TECHNOLOGY (SST):The different SST-determined conductor sizes used in Rocket 88 allow an exceptionally clear, clean and dynamic sound. BIWIRING: Rocket 88 is an exceptional Single-BiWire cable.
