The speaker cable model Type 4 was first introduced about 1983. It wasnt the prettiest cable, but the performance advantage of its polypropylene insulation was dramatic and much appreciated. Several evolutionary steps later, the current version of Type 4 was introduced in 1995a design whose foundation is so well balanced that it hasnt changed since thenand still isnt changing.

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%.

Features

HIGH PURITY CONDUCTORS - SOLID PERFECT-SURFACE COPPER+ (PSC+)
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 minimises distortion caused by grain boundaries, which exist within any metal conductor. The astonishingly smooth and pure Perfect-Surface Copper further eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other premium coppers.

SOLID CONDUCTORS
Eliminate harshness and confusion due to strand-interaction.

MULTI-LAYER CARBON-BASED NOISE-DISSIPATION
Multi-Layer carbon-based Noise-Dissipation plus Direction-Controlled conductors and shielding significantly lower noise-floor and reduce amplifier Transient-Intermodulation Distortion (TIM).

STAR-QUAD GEOMETRY
Balanced Star-Quad Geometry reduces time-smearing while preserving dynamics, and clarity.
