INTRODUCTION

The AudioQuest Leopard 72 V DBS tonearm cable is the best in its class. Thanks to the Pure-Surface-Silver (PSS) technology, distortion has been reduced to almost zero. In other cable designs with separate strands, distortion occurs at the boundary of each strand. Because the solid conductors in PSS are made of extremely pure silver, distortion is eliminated. The result is an extremely lifelike reproduction while maintaining the original clarity, details, and dynamic contrasts.

FEP AIR-TUBE INSULATION (FEP IS A FLUOROPOLYMER)

Any solid material next to a conductor actually becomes part of an imperfect circuit. Wire insulation and printed circuit board materials all absorb energy (loss). Some of this energy is stored and later released as distortion. However, air absorbs almost no energy and FEP is the best extrudable solid insulation, which absorbs less energy than other materials. The use of FEP Air-Tube insulation, with almost nothing but air around the solid conductors, improves the sound focus and dynamics of an audio system.

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. An unmatched dielectric causes a non-linear release of energy. This results in different amounts of time delay (phase shift) for different frequencies and energy levels. To prevent this unwanted phase shift, the "Radio Frequency Trap" has been developed. The RF Trap is also used in AudioQuest's Niagara series power products and ensures that no radio frequency noise is induced in the signal conductors (DBS, US Pat #s 7,126,055 & 7,872,195 B1).

CARBON-BASED 4-LAYER NOISE DISSIPATION SYSTEM

To prevent captured radio frequency interference (RFI) from modulating the equipment's grounding reference, AQ's Noise-Dissipation System (NDS) is required. Traditional shielding systems typically absorb noise/RF energy and then dissipate it to the ground of the components. However, the downside is that the critical "reference" grounding plane is modulated and distorted. This results in signal distortion. In the AudioQuest Leopard 72 V, the NDS includes alternating layers of metal and carbon-loaded plastic to "shield the shield" and absorb and reflect most of this noise/RF energy before it reaches the ground layer.
