Types 9 Low-Distortion & Low-Noise speaker cable is essentially Type 4 with better metal, and with added layers and techniques of Noise-Dissipation for more effective noise control than any previous Type 4 iteration. In addition, Type-9 conductors are a little bigger than previous 4-series cables. The conductors are a little farther apart, reducing interaction between adjacent conductors by 35%. Solid Perfect-Surface Copper+ (PSC+) conductors prevent strand interaction, a major source of ear fatiguing transient intermodulation distortion. The astonishingly smooth and pure Perfect-Surface Copper+ eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other premium coppers. The superior purity of PSC+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor. Multi-Layer carbon-based Noise-Dissipation plus Direction-Controlled conductors and shielding significantly lower noise-floor and reduce amplifier Transient-Intermodulation Distortion (TIM). Balanced Star-Quad Geometry reduces time-smearing while preserving dynamics, and clarity.
