OCC Silver Dart - Graphene Dielectric Speaker Cable

Category: speaker

Type: Speaker Cable


The OCC Silver Dart is the culmination of 3 years development and testing using our H-Wound™ stranding technique on large gauge conductors coupled with our newly developed Graphene doped conductive dielectric.  Utilizing our H-Wound™ stranding each  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 layers to prevent fallen or clipped strands during the assembly process. What this means is 100% identical cores before they are secured in our Audiophile Grade power connectors.

The Silver Dart’s OCC conductors are Cryo-Treated before extrusion and then undergo our thermal cleaning process to remove any external dirt, oils, and drawing residue from the conductor surface. This high voltage cleaning also puts a continuous voltage through the cable giving the Dart a sound and performance of a cable, which has been run-in for many months.

Silver Dart also uses our spaced layer “cable in cable” technique insulating this cable to an overall diameter of 23mm using a power cable inside a power cable design that is uniquely our own and adding it’s signature sound.

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.
This is a two-stage process. In the first stage we 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.

UltraSonic 7 High Voltage / Thermal Break-in
This is a two-stage process. In the first stage we 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, we increase the voltage 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 customized transformer wire-stranding machine. We 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 meter. 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 meter; 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, we can guarantee 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. Our new H-Wound™ stranding technology allows us to protect the delicate electrical signal being transferred through our cables. Combined with Zavfino’s state of the art manufacturing techniques, our precision matched OCC Copper (Cu) and Silver (Ag) conductors used in the Silver Dart™ A/C power cord bring an unequalled purity and honesty to all forms of music. The results are previously unheard details, finesse, and accuracy across the frequency spectrum.
