Description
Newly updated and tweaked to perfection Prima MKII speaker cable utilizes more OCC single crystal copper strands in a multiple strand litz construction with an individually insulated silver coated core with Japan sourced LDPE Dielectric. Prima MKII also has a tighter conductor twist before extrusion and the insulated pairs are also twisted at a higher pitch rate than the previous Prima. Using a tight strand/high pitch lay this 9AWG speaker cable can handle the most demanding systems and loudspeakers on the market. New to the MKII is our Delrin insulated BFA speaker connectors which are a mix of pressed formed copper sheet with lightweight aluminum shells which don’t come into contact with the gold plating. Other connector variations such as spades, and locking banana are available by contacting us through the website.
The Prima MKII like all of our cables goes through our new Ultra Sonic cleaning process where we run the raw copper through a water bath that is super charged to burn away dirt, oil, residue and impurities on the surface of the wire. This Ultra Sonic Bath also has the added unique effect of giving our cables a pre-burn sound that could take hundreds of hours to achieve through normal use. Prima MKII is has Cryo treated bare conductor before extrusion.

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.
