Types 5 Low-Distortion & Low-Noise speaker cable is essentially Type 4 with better metal, and with conductors that are a little farther apart, reducing interaction between adjacent conductors by 35%. Solid Perfect-Surface+ Sonic-Signature Conductors. Carbon-Loading and Direction-Controlled Conductors. Star-Quad Geometry. A finessed combination of grainless-sounding Perfect-Surface Copper+ Sonic-Signature conductors, plus Long-Grain Copper, enable a smooth and natural "lack-of-character". Carbon-Loading and Direction-Controlled conductors provide effective Noise-Dissipation, minimizing noise modulation and amplifier distortion. Balanced Star-Quad Geometry reduces time-smearing while preserving dynamics, and clarity.
