Columbia receives Audioquest’s wonderful PSC+ copper conductors; ultra pure copper that has received Audioquest's

proprietary Perfect Surface treatment for superb and linear high frequency reproduction. Polyethylene tube insulation for all three conductors minimizes the conductor's interaction with the insulation for greater air and transparency.

The 72V DBS system smooth's frequency response and the Cold-Weld connectors eliminate harshness. The three-layer Noise-Dissipation System protects the entire cable from the deleterious effects of airborne noise. Standing on its own, Columbia is a wonderful sounding cable; capable of bringing out the best in any system, but perhaps the most astonishing thing about Columbia is how close it sounds to its big brothers at a fraction of their prices.

AudioQuest's Columbia analogue audio cables transfer signals with almost no noise or signal loss. Each cable features three solid copper conductors to effectively eliminate electrical and magnetic interference that can add brittleness to the sound. And AudioQuest uses an extremely pure grade of copper to minimize harshness and distortion, for outstanding clarity.

Dielectric-Bias System

Most higher-end cables require a break-in period before they perform their best. A charge builds up in the insulation through continual use, increasing the efficiency of the cable. This charge can dissipate when the cable's not in use, giving you less than optimal performance until it builds up again.

AudioQuest's Dielectric-Bias System (DBS) eliminates this break-in period. A small battery pack attached to the cable polarizes the insulation with a 72-volt charge, giving you clear, expressive sound from your system every time you turn it on. This also helps eliminate the time delay that can create audio distortion.

Air tube insulation and shielding

Each conductor has its own insulating air tube, which prevents information smearing better than foam insulation. An additional layer of shielding negates almost all electronic noise, for the cleanest signal possible.

High-quality connectors eliminate the weakest link

Columbia cables feature RCA connectors made of silver-plated copper. The connectors are fastened by cold welding — a process that uses high pressure and silver paste to minimize signal loss. By contrast, solder tends to impede the signal, and the heating of the copper conductor during soldering can negatively affect its performance.


  • 3 solid, high-grade Perfect-Surface Copper+ conductors per cable
  • Dielectric-Bias System with attached battery pack (batteries included) maintains constant 72V charge for optimal performance
  • PE Air Tubes to minimize information smearing
  • conductors labelled for proper direction of signal flow
  • cold-welded silver-plated RCA/XLR plugs
  • textile braid cable cover
  • warranty: 5 years
  • Please note that the longer pairs of this cable are a special order item, and so there will be a short delay in you receiving them.
