Zavfino - Silver Dart - Interconnect Cables

The Zavfino Silver Dart cable is the culmination of 3 years of development and testing using the H-Wound™ stranding technique on large gauge conductors coupled with the newly developed Graphene doped conductive dielectric.  Utilizing Zavfino H-Wound™ stranding each power core is guaranteed “Zero Strand Loss” during assembly as the final horizontal silver OCC layer not only allows for perfect pitch across the conductors but also acts as a barrier layer to prevent fallen or clipped strands during the assembly process. What this means is 100% identical cores before they are hand assembled with our custom audio connectors.

UltraSonic 7 High Voltage / Thermal Break-in

This is a two-stage process. In the first stage draw the bare conductor 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, we 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.

Zavfino’s H-Wound™ + Zero Strand Loss

Drawing on more than 18 years of manufacturing experience, Zavfino has developed a remarkable new technique for twisting stranded wire tightly around a central solid-core conductor. An electrical phenomenon commonly known as the “skin effect” occurs when electrons move through any solid core conductor. Higher frequencies travel along the outside (the skin) of the conductor faster than midrange and lower echelon frequencies. This results in smeared PRaT, muddled instrumental timbres, and an unnatural sound. Zavfino’s new H-Wound™ manufacturing technique negates the skin effect. Originally developed by OEMs Siemens and Klangfilm, Zavfino uses a customised transformer wire-stranding machine. Zavfino further modified the gears in this machinery to create windings at a slower RPM ratio with a much tighter pitch. This patented manufacturing process enables us to twist the wiring at the tightest pitch possible without overlapping the wire strands. Most wire-stranding machines can only fabricate windings up to a maximum of 300 twists per metre.

Setting the bar far higher, Zavfino’s patented H-Wound™ cable winding machine creates a pitch rate of 14,000 to 16,000 twists per metre; which is unmatched by any other audiophile cable maker. Zavfino’s new Zero Strand Loss™ manufacturing technique protects the bundled conductors from being damaged during stripping and termination. By ensuring that each core has zero chipped, cut, or mangled strands guarantees that each insulated core is 100% identical. For audiophiles, the sonic results of tighter windings and Zero Strand Loss™ conductors are cables with quieter backgrounds, remarkable timbral accuracy, lifelike PRaT, jaw-dropping mid-range resolution, and superior low-frequency extension. The Zavfino new H-Wound™ stranding technology allows the protection of the delicate electrical signal being transferred through the cable. Combined with Zavfino’s state-of-the-art manufacturing techniques, precision-matched OCC Copper (Cu) and Silver (Ag) conductors used in the Silver Dart™ Series of cables bring unequalled purity and honesty to all forms of music. The results are previously unheard details, finesse, and accuracy across the frequency spectrum.

Deep Cryo™ Treatment

All of the conductors used in our cables undergo Deep Cryo™ treatment before the insulation is extruded over the metals. Our 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 we 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.

Zavfino is the first audiophile cable OEM to integrate graphene insulation into high-end A/C power cables as a dielectric shield. After more than two years in development with a leading American graphene polymer research company, they unveiled the new proprietary ZGRAPh-LDPTM conductive shielding/dielectric, first used within the Silver DartTM OCC A/C power cable.The results of using ZGRAPh-LDPTM

1. Superior protection from electromagnetic interference as the graphene contour moulds to our copper shields and prevents EMI spikes. The end result is improved grounding and vastly superior signal transmission.
