HARP was discovered through Gabriel’s research into ‘current drift’ and audio frequency current resonances that occur in speaker cables. Theoretically, a speaker cable may develop current resonances in the audio band, being roughly analogous to standing waves (modals) in room acoustics. The ‌‌HARP module acts as a current mode diffraction device that breaks up these resonances, improving the perceived resolution and coherency of the system.

‌‌ArNi® is a type of wire created by Shunyata Research designed to be the finest quality wire available for audio purposes. It begins with the highest purity of copper available – OFE C10100 or Ohno (single crystal). Then it is formed in virtual hollow tubes eliminating skin effects and eddy current distortions. In addition, the wire undergoes our proprietary KPIP™ process.

Shunyata’s VTX-Ag cables are uniquely constructed with both an inner, center conductor made of pure silver and an outer concentric ring conductor made of pure copper. It’s made using the finest fluorocarbon insulation to minimize dielectric absorption and re-radiation which translates to an improvement in resolution and clarity. VTX-Ag delivers the speed and clarity of silver and the midrange warmth and three dimensional power in the lower octaves of copper without imparting any of the negatives associated with either metal. – The best qualities of silver and copper combined.

Shunyata Research uses only the highest purity of copper available for the production of its wire products. ‌‌OFE Alloy 101 or ‌‌C10100 is the highest grade of copper with a minimum 99.99% purity and a conductivity rating of 101% IACS. OFE stands for oxygen-free electrolytic and supersedes the term OFHC (oxygen-free high conductivity). ‌‌C10100 is the only grade of copper that comes with a written certification of purity.

Crimping, soldering, brazing and cold soldering are all inferior methods of joining two wires or terminals together. ‌‌Sonic welding uses high energy sonic waves to literally join two metals together at a molecular level. There is no solder or intermediary metals involved in the process.
