Supreme-quality interconnects, fabricated with the best available materials and construction, cost-no-object. Hand-built by Delphi Aerospace on behalf of VSA. Cast, single crystal laboratory-grade copper, Teflon insulation, and Patent Pending Spiral Helix winding geometry designed to eliminate magnetic field reactance distortion. Uses very interesting Viablue plugs from germany which are a twist lock design but with a difference, locking clockwise, pins made of bronze. Easily compete with leading cable brands but at half the price. Thanks for looking.
