Audioquest Columbia Audio Interconnect Cable with 72V DBS

Columbia is now shipping with 72V DBS!

NOISE-DISSIPATION SYSTEM:  100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment’s ground-reference requires AQ’s Noise-Dissipation System. Metal and Carbon-Loaded synthetics prevent most RFI from reaching the equipment’s ground-plane.

SOLID PSC+ COPPER:  Perfect-Surface Technology applied to extreme-purity copper eliminates irritation and provides tremendous clarity.

DIELECTRIC-BIAS SYSTEM (DBS, US Pat #7,126,055):  All insulation slows down the signal on the conductor inside.  When insulation is un-biased, it slows down parts of the signal differently, a big problem for very time sensitive multi-octave audio.
AudioQuest’s DBS creates a strong stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS pack’s batteries will last for years. A test button and LED allow for the occasional battery check.

PE AIR-TUBES:  Air is a nearly perfect dielectric. Once the DBS is attached (for 2 weeks), the normal irritation caused by un-biased Teflon is eliminated.

TRIPLE-BALANCED:  Optimized for RCA or XLR
