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 FEP is eliminated.

TRIPLE-BALANCED:  Optimized for RCA or XLR

Needle Dr reviews the Audioquest Columbia
Researching interconnects can be dizzying, with all the options nowadays. Certain questions always arise - Copper or silver? Braided or solid core? What connectors? Too often, what gets lost in all the research is the most important aspect of all - sound quality. The Audioquest Columbia interconnects bring together years of research and development, and address sound quality first and foremost. With a 72V DBS system in place, shielding and directionality are king. The rhythm and pace of recordings is delivered with uncanny precision, making it one of the more fun cables you can implement into your system. Able to be fitted with quality RCA or XLR connectors, the Audioquest Columbia is a perfect fit for any application.
