Audioquest Robin Hood Zero Speaker Cable
SOLID PERFECT-SURFACE SILVER (PSS) & SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS
Solid conductors prevent electrical strand-to-strand interaction, major sources of distortion. Surface quality is critical because a conductor can be considered as a rail-guide for both the fields within a conductor, and for the magnetic fields that extend outside the conductor. The astonishingly smooth and pure Perfect-Surface Copper+ eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other premium coppers. Extremely high-purity Perfect-Surface Silver further minimizes distortion caused by grain boundaries, which exist within any metal conductor.
ZERO TECH: NO CHARACTERISTIC IMPEDANCE FOR UNCOMPRESSED CURRENT TRANSFER
The integrity of any audio transient (instantaneous peak-to-peak voltage swing and current) delivered from a power amplifier to a loudspeaker has always been compromised. Whether the amplifier is valve or transistor, regardless of class of operation, the amplifier’s source impedance and loudspeaker’s load impedance are never critically matched. The speaker cable’s characteristic impedance is yet another culprit in a highly compromised non-linear electrical circuit. AudioQuest has always stated that all cables cause damage because the output is never as good as the input. However, by eliminating a speaker cable’s characteristic impedance, AQ’s ZERO Tech is an unprecedented step towards reducing that damage. The result is greater dynamic contrast, better audio transient response, and bass slam that are rendered seemingly without effort because the cable is not electrically restricting (strangling) the music.
