The WEL Signature Reference Series Tonearm Cable is the culmination of over 30 years of research, trial, and error, and just plain old-fashioned listening. WEL Signature incorporates all of AudioQuest's best techniques, materials, and practices such as Perfect-Surface Silver conductors, FEP Air-Tubes, Noise-Dissipation System and our most advanced, custom-machined RCA and XLR connectors. WEL Signature will leave you breathless and never wanting for more.

Solid perfect-surface silver (PSS) conductors

Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest's highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimises distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.

FEP air-tube insulation (FEP is a fluoro-polymer)

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 later released as distortion. Air, however, absorbs next to no energy, and FEP is the best extrudable solid insulation, absorbing less energy than other materials. The use of FEP Air-Tube insulation, with almost nothing but air around the solid conductors, improves the sound of an audio system's focus and dynamics.

Dielectric-bias system with radio frequency trap

All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio-frequency noise will not be induced into the signal conductors from the DBS field elements. 

Carbon-based 4-layer noise-dissipation system

It's easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. NDS's alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.
