AudioQuest Athena + BigFoot BiWire Combo Speaker Cable w/ RF/ND-Tech for BiWireable Loudspeakers

• BiWiring: When a speaker has separate Bass and Treble inputs, running separate cables to the Bass and Treble inputs significantly reduces distortion. BigFoot is the Bass-Only cable for Lone Ranger and Athena speaker cables. A BiWire Combo with Bass-Only and ZERO cables joined together at the amplifier is usually most convenient, though joining them is optional.
• RF/ND-Tech: A cable’s ground leads act as an antenna, making them subject to induced Radio-Frequency (RF) noise. Employed in BigFoot, AudioQuest’s RF/ND-Tech greatly reduces the resulting distortion and signal masking, yielding unprecedented levels of noise dissipation across the widest bandwidth of radio frequencies possible. The unique circuit design uses a common-mode phase-cancelling array, providing linear noise dissipation across the entire length of the cable.
• ZERO-Tech (No Characteristic Impedance): The only way to prevent characteristic-impedance mismatch-effects between a cable and its attached source and load circuits is for the cable not to have a characteristic-impedance. ZERO-Tech accomplishes this by eliminating any electrostatic field between the cable’s high and low signal conductors — enabling uncompressed current transfer. All-important transient current is unrestricted and RF Noise-Dissipation is more effective and linear.
• Solid No-Grain Copper (NG-C) and Perfect-Surface Copper+ (PSC+) Conductors: Solid conductors prevent strand-interaction, a major source of dynamic distortion. BigFoot's high-purity PSC+ copper minimizes distortion caused by grain boundaries and maximizes RF-Noise Dissipation. Athena's NG-C comprises PSC+ for its inner 90% and extreme-purity, essentially single-crystal, copper for the conductor’s crucial outer 10%.
• Linear Noise-Dissipation: The Earth is permeated with RF-Noise from satellites, cellular, WiFi, etc. Combining RF/ND-Tech with ZERO-Tech, Graphene+Carbon Mesh-Network, direction-controlled metal, 72v DBS, and Perfect-Surface Silver shield drains in a BiWire Combo produces a remarkably effective solution against sound-damaging RF-Noise.
• 72v Dielectric-Bias System (DBS) with RF Noise-Trap: Insulation is also a dielectric that acts like a shunt-filter. Biasing the dielectric both minimizes dielectric-noise and linearizes the filter, significantly improving wide-bandwidth dissipation of induced noise.
• RF Shield Drains: Significantly aid in the efficient dissipation of RF-Noise. Athena and BigFoot employ superior Perfect-Surface Silver shield drains.
• Cold-Welded Red-Copper Spades or Bananas: Cold-Welding avoids the introduction of heat and distortion-causing materials like solder. The bare parts are submerged (hung) in silver instead of tumbled in a lower-grade solution. Speaker breakouts and plug casings are synthetic, not metal, to avoid inducing RF Noise into the conductors.
• Directionality: All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. A fundamental aspect of AudioQuest’s multifaceted Noise-Dissipation technology, Direction-Controlled Conductors ensure induced noise is dissipated and drained properly.
