Zavfino 1877Phono 12 AWG OCC Jumpers with 24k Gold Spades.  These pure OCC copper jumpers are carefully hand assembled to ensure that each spade connector is securely attached and has full contact with the internal high purity OCC wires. Zavfino's  24k gold plated spade connectors are made to fit most modern binding posts and are high purity CNC machined copper.   This is a set of 4 jumpers, for use with bi-wire enabled speakers to replace the often cheap, nasty and poor sounding metal strips used by speaker manufacturers.

Deep Cryo™ Treatment All of the conductors used in these jumper cables undergo Deep Cryo™ treatment before the insulation is extruded over the metals. Zavfino's research has proven that the conductor—and only the conductor— benefits from cryo-treatment. Materials such as polyvinyl chloride (PVC™), Teflon™, PE, and Silicon™ can all be adversely affected by cold-temperature annealing. Cryo-treating non-conductors and insulating materials can cause them to break down and become brittle.  The purity, size, and molecular structure of each conductor determine the specific temperature within the -186ºC to - a 196ºC range that Zavfino  cryo-treat it at.  Zavfino’s research into cold temperature physics has proven that the absolute lowest temperature is not necessarily the best for cryo-treatment. UltraSonic 7 High Voltage / Thermal Break-in This is a two-stage process. In the first stage the bare conductor is drawn through a ceramic die into an ultrasonic cleaning chamber that bombards the conductor with multiple ultrasonic frequencies. This emulsification process removes all debris from the surface of the wire down to the molecular level and leaves absolutely zero residues. After each individual wire is processed, Zavfino strand it into bundles and then subject the bundles to further treatment. During the second stage of the ultrasonic burn-in, the voltage is increased to a higher level that’s just below the threshold of the conductor. This adjustment in temperature allows us to get a unique “break-in effect” normally associated with cables that have had 30 to 40 hours of signal and/or current run through them.
