BALANCED REFINEMENT COPPER (BRC)
Unlike most of our rivals who religiously adhere to the utilization of Oxygen Free Copper (OFC), we have elected a different touch with BRC - Balanced Refinement Copper. Every ounce we use is mined in the Ural region of Russia, which undergoes electrolytic refinement to achieve an entirely uniform and defect free crystal structure with unrivalled conductivity, high ductility and resistance to tearing.
Extensive analysis was combined with listening tests to determine the list of chemical elements with the most negative impact on the sound: Si, S, As, Ge, Sn, Cr, Mn, Fe, Co. On the contrary, the residual presence of silver (Ag) and lead (Pb) is much more benign as it increases the recrystallization temperature and helps the wire retain high electrical conductivity after it has been subjected to stress.
This effect might be likened to mineral water. Many impurities are definitely unwelcome but the presence of other substances in trace amounts results in a water that is preferable in taste terms to “purer” distilled water. Seeking to achieve a similar benefit in conductors, we place orders for copper with the specified impurity ratios. Named Balanced Refinement Copper (BRC) it reveals stunning musical fidelity, rendering information exactly as it was intended without any coloration.
INSULATORS
Complex insulation, which is a combination of conductor insulation and dielectric binding, is what Tchernov Cable is widely renowned for. We opted for a high purity Russian-made non-polar polyethylene (PE) without any artificial polymerization accelerators that do have polar molecular structure to obtain the industry-leading level of dielectric permittivity. Different PTFE tapes are used for dielectric binding and our cutting-edge SATI® insulation, which has no equal in the High End industry to date.
JACKETS
The importance of quality jacketing can’t be underestimated as numerous vibrations have a critical influence on the audio band. The innovative Combined 2-layer SPVC jacket with the air-foamed inner layer, pioneered by Tchernov Cable exemplifies long-term dielectric stability, efficient absorption of acoustic noise and vibrations along with the enviable flexibility. There is nothing similar on the market to date.
However, in our top-end Reference & Ultimate cables the remarkable thermoplastic polyurethane (TPU) Elastollan® is used to reach even higher damping efficiency. Developed by BASF, Elastollan® provides high viscosity, mechanical strength and unmatched vibration absorption, as well as incredible resistance to abrasions, tears, temperature fluctuations, and aggressive chemicals.
ORGANIC DYES & ADDITIVES
The unique Russian-made purely organic dyes with the exact SPVC molecular matching are used for jacket coloring. They have no analogs elsewhere in the world as they do not contain any metal ingredients that degrade the consistency of insulating materials. The antistatic treatment eliminates the electrostatic effect that severely deteriorates signal transmission. The stabilizing additive serves for the SPVC mass homogeneity during its extruding and subsequent hardening.
SOLDER SFS/AG
Tchernov Cable uses its own original solder with a low melting point of only 180 °C and perfect silver and copper ratios, developed from the outset.
The presence of a special flux adds the unbeatable soldering homogeneity. The optimal diameter of 0.8 mm makes termination with any connector type straightforward. The SFS/AG solder is manufactured to our technical specification in Japan.
