AudioQuest Perfect Surface Copper, Air-Tube Insulation, and Triple-Layer Shielding Ensure the Best Sound for Your Dollar

Excellent resolution and dynamics coupled with an even tonal balance make Diamondback a great choice for all music lovers and audiophiles on a budget. AudioQuest’s PSC copper conductors get air tubes, triple balanced geometry and welded connectors making Diamondback ultra-smooth and extremely resolving. Many sophisticated design techniques, superior materials, and an exceptional termination system combine to make AudioQuest Diamondback possible. The results have put the Diamondback at the top of any price-to-performance list by anyone who demands proper cables, yet cannot spend a fortune.

"The Diamondback has a discerning and revealing treble with good timing and separation...[Diamondback is] capable of excellent sound quality because it melds the vocals and music with authority. It is never out of control..."
– HiFi World

Diamondback is Triple-Balanced. This means there are three identical insulated conductors, in addition to a separate conductor underneath the 100% coverage foil shield. When used with XLR connectors and balanced electronics, the two positive signals (inverting and non-inverting) and the negative, all get the same low-distortion conducting path. The shield is attached to chassis ground through the case of the XLR, providing extremely effective shielding without contaminating the quality of the negative conducting path. When Diamondback is fitted with RCA plugs, two conductors are used together for the much higher potential across the negative connection, providing a substantial performance advantage. The shield is only attached at one end, providing total shield coverage without compromising the negative conducting path.

Conductors: All of Diamondback’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 Diamondback’s very clean sound.

Metal: PSC (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 conductor. For fifteen years AudioQuest has pioneered the use of superior metals; yet even we were surprised by this huge leap in performance. PSC clearly outperforms previous AQ metals that cost over ten times as much.

Insulation: Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation, circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. Diamondback uses air filled FPE (Foam Polyethylene) insulation on both conductors because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in FPE, it causes much less of the out-of-focus effect common to other materials.

Cold-Weld System: Novel plug design enables a perfect heat-free connection between cable and plug. XLR plugs are also available. Diamondback’s silver plated RCA plugs use a patented design that eliminates the distortion caused by the extra contact inside most plugs. Because the ground shells are stamped instead of machined, the metal can be chosen for low distortion instead of for its machinability. A combination of these major ingredients, and many more subtle details add up to explain how Diamondback can sound so clean, clear and dynamic.
