Powerful, Pure-bred Performance
A Greyhound's combination of long legs, deep chest, flexible spine, and slender build make it an excellent hunting and racing breed, capable of reaching speeds in excess of 64 kilometers per hour (40 MPH). However, the gentle, intelligent greyhound would just as well spend its day simply and quietly enjoying long naps in the soft shade. Greyhounds rarely bark, are very patient, show great devotion and affection toward their families, and exhibit a surprisingly friendly attitude toward people and other dogs. But don’t be misled by their distinctly slim conformation: Greyhounds are in fact exceedingly healthy, powerful animals, and they make loyal, loving companions for people young and old.
AudioQuest's Greyhound offers pure-bred performance in a subwoofer cable, featuring Solid 0.5% Silver Conductors, Foamed-Polyethylene Insulation, Metal-Layer Noise-Dissipation System (NDS), Hyperlitz Coax Geometry, and Cold-Welded Gold-Plated Plugs.
Solid 0.5% Silver Conductors
Solid conductors eliminate strand-interaction distortion and reduce jitter. Solid silver-plated conductors are excellent for very high-frequency applications. These signals, being such a high frequency, travel almost exclusively on the surface of the conductor. As the surface is made of high-purity silver, the performance is very close to that of a solid silver cable, but priced much closer to solid copper cable. This is an incredibly cost effective way of manufacturing very high-quality subwoofer cables.
Foamed-Polyethylene 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. Greyhound uses air-filled Foamed-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 Foamed-PE, it causes much less of the out-of-focus effect common to other materials.
Metal-Layer Noise-Dissipation System (NDS)
100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment’s ground reference requires AQ’s Noise-Dissipation System. Noise-Dissipation System prevents a significant amount of RFI from reaching the equipment’s ground plane.
Hyperlitz Coax Geometry
In Greyhound, a perfect circle of eight negative conductors spiral around a single larger positive conductor, creating a cable with a large cross-sectional area, minimizing skin effect, and providing low resistance.
Cold-Welded Gold-Plated Plugs
This plug design allows for a connection devoid of solder, which is a common source of distortion. Because the ground shells are stamped instead of machined, the metal can be chosen for low distortion instead of machinability.
Grounding
Sometimes there is a hum problem unless the subwoofer and AV receiver (or surround-sound processor) are attached to each other using a separate wire. If your system has a hum problem, try attaching the little spade-lug tails to the metal chassis of the subwoofer amplifier and to the chassis of the sending component. Usually, this extra wire will not be needed.
