AudioQuest 4.0M PR EARTH RCA DBS Carbon Pair

The AudioQuest Earth analogue interconnects are designed for mid to high end sytems and deliver outstanding performance and value.

The Earth interconnect features Triple-Balanced Geometry and asymmetrical signal and ground impedance. When used single-ended with RCA plugs, the 1 larger conductor is used for positive and the 2 single-gauge-smaller conductors are combined to provide a ground reference which has 59% lower impedance than the signal conductor.

Solid Perfect-Surface Copper+ (PSC+) Conductors :

Strand interaction is the single greatest cause of distortion in a cable. Semi-Solid Concentric Packed Conductors avoid many strand-interaction distortion mechanisms. Solid-core conductors offer a complete and compelling solution to this problem.

Conductor metal quality is critical for the best cable performance. The conductor surface is the only area of the conductor with 100% current density at all frequencies. The smoothness of the conductor surface is imperative because the surface is a guide rail for the entire energy envelope. The best copper and silver conductor metals have fewer grain boundaries and low oxygen content for low distortion and high performance.

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 Earth'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 Earth’s very clean sound.
