Solid Core Conductors
Strand interaction is the single greatest cause of distortion in cable, and one of the easiest to avoid. Whenever current crosses the oxidized contact between bare strands, the signal will be altered. In addition, the magnetic fields of the various strands are constantly interacting, causing confusion (smearing) and causing the contact pressure between strands to be constantly modulated. AudioQuest’s solid core conductors are the complete solution to this problem.
The sheer amount of metal used in an audio cable is much less important than the quality. Since the surface of a conductor has 100% current density at all frequencies, the surface most defines the sound quality of the whole conductor. AudioQuest’s Perfect Surface metals start with very high purity copper or silver, which minimize distortion caused by grain boundaries that exist with any metal conductor. These are then drawn and annealed though a novel proprietary process which creates an exceptionally soft silver or copper conductor with an astonishingly smooth and uncontaminated surface. Extreme high-purity solid Perfect-Surface Silver (PSS) is the ultimate embodiment of this conductor technology.
Conductor material quality makes a world of difference. Impurities in the conducting material cause a harshness signature similar to strand interaction. The best materials have very long grain structures and superior contact between the grains - all of that going on inside every single strand! The quality of a conductive path is most defined by a conductor’s surface. The surface is a meeting of the area of greatest current density inside the conductor, and of the greatest external magnetic field density. The conductor surface is like a rail-guide for the entire energy envelope.
Noise, in the form of RF energy, is the mortal enemy of good sound. Our environment is more contaminated with RF than ever due to the huge proliferation of RF radiating devices like computers and mobile phones. Traditionally RF energy is routed to ground through the use of a “shield” consisting of either a braided metal or foil. This “draining” of RF to ground causes a modulation of the ground plane, which in turn causes a form of signal modulation.
The Noise-Dissipation System greatly reduces the effect of this modulation. A combination of metal and carbon-loaded synthetics prevents most RFI from ever reaching the equipment's ground plane. The carbon-loaded synthetics have the ability to turn some of this RF energy to heat, to very effectively “lose” this energy. Metal, used in a passive manner, is used to act as another method of dissipating and reducing the incoming RF. This results in dramatically less modulation of the signal, less distortion and better sound.
Making the perfect connection between conductor and connector is not a simple process. There are three accepted ways to make the connection between a cable and an RCA or XLR plug. Solder is by far the most common method of connection. Resistance welding is clearly superior to even the best solder. However, just as solder introduces an inferior layer of differing material, causing distortion and reflections, so does welding. The alloy created at the interface of cable and plug is far superior to solder, but it is still an undesirable intermediary layer. After so much attention to the quality of the conductor and connector, the contact system deserves just as much consideration.
AudioQuest’s new Cold-Weld System solves this problem with a superior connection that ensures that the structural integrity of the conductor is kept completely intact. The Cold-Weld System refers to a combination of high pressure at the point of contact and the use of silver impregnated paste.
In a very similar manner to the way a compass needle aligns itself to the Earth’s magnetic poles, the AudioQuest Dielectric-Bias System (DBS) featured on all WEL Signature products causes the molecules of a cable’s insulation to align themselves relative to an electrostatic field. A 72v DBS battery-pack attached to inner and outer DBS field elements creates a strong and stable field. This keeps a cable's insulation fully polarized all the time, something no level of signal can come close to accomplishing. The result is considerably more transparency and dynamics. Because DBS battery packs are attached when the cables are assembled, they do not require an additional run-in period. Because there is no “load” on the batteries, they will last for years. A test button and LED allow for occasional verification of battery charge.
Electrostatically unorganized insulation causes non-linear phase error; different amounts of time delay for different parts of the signal. Polarized (aligned) insulation eliminates almost all of this distortion for much smoother and easier sound from a quiet, black background. Information and emotion come through as never before.
