AudioQuest Columbia Interconnect Cable RCA-RCA 1.0m Pair

Columbia improves upon one technology and introduces another. AudioQuest's Noise-Dissipation System receives an additional layer, which further reduces the modulation of noise on the ground plane. Next, we integrate Dielectric-Bias System. DBS reduces the loss and distortion of the audio signal, preserving the subtle nuances and textures. Your music will appear from a blacker background with greater dimensional space.

Solid Perfect-Surface Copper+ Conductors
Perfect-Surface Copper+ has an astonishingly smooth and pure surface. Proprietary metal-processing technology protects the wire’s surface at every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure and smooth as possible, it becomes a wonderfully low-distortion PSC+ conductor. PSC+ is manufactured by applying the same exceptional technology to an ultra-pure copper. The resulting sound quality is even more focused and simply less in the way. For over 30 years AudioQuest has pioneered the use of superior metals; yet even we were surprised by the huge leap in performance made possible with Perfect-Surface Technology. PSC+ simply outperforms all previously available copper metals at any price. All of Columbia’s conductors are solid. Electrical and magnetic interaction between strands in a conventional cable is the greatest source of distortion, often causing a somewhat dirty, harsh sound. Solid conductors are fundamental toward achieving Columbia’s very clean sound.

Polyethylene Air-Tube Insulation
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. All of Columbia’s conductors use PE Air-Tube Insulation because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. PE Air-Tube Insulation causes much less of the out-of-focus effect common to other materials.

Dielectric-Bias System
All insulation slows down the signal on the conductor inside. When insulation is unbiased, 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 that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check.

Carbon-Based 3-Layer 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.

Triple-Balanced Geometry
The three conductors in Triple-Balanced Columbia cables ensure that whether prepared with RCA or XLR plugs, the positive and negative signals have equally low-distortion conducting paths. The 100% coverage shield is never used as an inferior conductor.

Cold-Welded Direct-Silver Plated Pure OCC Copper System
This plug design enables a perfect heat-free connection between cable and plug. The connection between the plug and conductors is made using AQ’s Cold-Welded System, which provides a superior connection that ensures that the structural integrity of the conductor is kept completely intact. The Cold-Welded System refers to a combination of high pressure at the point of contact and the use of copper- or silver-impregnated paste. (Columbia’s copper conductors get copper paste.) XLR plugs are also available.

Shipping Rates

We calculate your shipping rate based on the total weight of your items and your delivery address. Standard shipping to the UK Mainland (excludes Northern Ireland, Isle of Man, Channel Islands) is free, except where specifically indicated. Don't worry, you'll always see the final shipping charge displayed before you reach the payment step (on the checkout page).

Carriers

We despatch the bulk of our UK mainland items on a 24 hour service.  Non-Mainland locations – Isle of Man, Isle of Wight, the Scilly Isles, the Scottish highlands and Islands, the Channel Islands and Northern Ireland may take a day or so longer. Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as UPS and occasionally by a Pallet service.

Order Tracking

If a tracking # is provided by the carrier, we will update your order with the tracking information. Please note that some orders will not have tracking numbers.
