Our take on the AudioQuest CV-4

AudioQuest CV-4 speaker cables feature an innovative design and top-quality materials to help your high-performance audio system deliver optimal sound. AudioQuest takes their own innovative approach to cable design based on years of in-house research, carefully engineering their cables to transfer signals as faithfully as possible.

Quality construction

Solid conductors improve accuracy and clarity

Each of the cable's four conductors is a single, unbroken strand of pure copper, which ensures highly efficient signal transfer with minimal loss. Solid conductors eliminate electrical and magnetic interference that can add brittleness to the sound with multi-strand conductor cables.

Precise cable geometry

The CV-4 uses two 17-gauge and two 20-gauge conductors. This difference in diameter reduces the possibility of distortion caused by any particular conductor's sonic "signature." A specialized spiral arrangement of the four conductors minimizes potential signal interaction, resulting in sound that's clearer and more dynamic.


DBS

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 48-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 jitter.


High-quality connectors eliminate the weakest link

The CV-4 cables feature banana plugs, fastened by cold welding — a process that uses high pressure and copper paste to minimize signal loss. By contrast, solder tends to impede the signal, and heating the copper can negatively affect its conductivity.

Features

Overview: The AudioQuest CV-4 speaker cables feature multiple solid conductors in a Star-Quad Geometry Design. Each cable is equipped with a 48-volt DBS pack which aligns the molecules in the dielectric, and enhances performance. Each cable is terminated with two PK-BFA banana plugs at each end.

Conductors: The CV-4 has a total of four solid conductors: Two 20-gauge Perfect-Surface Copper+ (PSC+) conductors and two 17-gauge PSC+ conductors. Overall, the combination of conductors is equivalent to 15 AWG (1.54 mm²).

Star-Quad Geometry: The relationship between conductors defines some of a cable's basic electrical values (capacitance and inductance). Designers at AudioQuest have aligned the four conductors in a spiral configuration to effect performance. The Star-Quad design of the CV-4 delivers significantly better dynamic contrast and clarity than if the same conductors were run in parallel.

Perfect-Surface Copper+ (PSC+): The CV-4 uses extremely high-purity PSC+ conductors. The conductors are solid, which prevents strand interaction, a major source of distortion. The extremely smooth and pure Perfect-Surface conductors eliminate harshness and greatly increase clarity, compared to OFHC, OCC, 8N, and other coppers. Extremely high-purity PSC+ further minimizes distortion caused by grain boundaries, which exist with any metal conductor.

Dielectric-Bias System (DBS): Each CV-4 cable has an attached 48-volt Dielectric Bias System (DBS) pack to enhance performance. This patent-pending system eliminates non-linear phase shifts caused by the dielectric properties of the cable insulation. The DBS pack puts a continuous 48-volt potential (DC bias) between the pin in the very center of the CV-4 and the outer shield-like layer, which fully aligns and polarizes all of the dielectric material in between. The system uses the same concept as continuously leaving your components powered on to make them sound better. A test button and LED allow you to occasionally verify battery performance.

Terminals: Each CV-4 cable is terminated with a pair of silver BFA/Banana plugs on each end. The BFA/Banana compression plug offers more surface contact than spade connectors, and better contact pressure than regular banana plugs.

Directionality: Each speaker cable is clearly marked for directionality for best performance. The breakouts (where the single cable splits into separate terminated conductors) are either marked "Speaker End" or "Amp End" to guide you. The DBS packs are both located on the "Speaker End" of each cable.
