SC Tchaikovsky speaker cables:


The SC Tchaikovsky offers solid core copper leads suspended in air within a framework of ultra low dielectric fabrics and PTFE tubing. With this cable build we have achieved an effective dielectric constant of 1.0018 with a signal transfer speed of 299253,8 km/h or 99.82 % of the speed of light making this one of the fastest speaker cables in the world - only rivaled by our Ravel and Beethoven cables. With gold z-plug or spade connectors (Speakon or unterminated bare wires optional), pure silk brocade cable sleeves, 4 x 12 AWG UP-OCC 7N solid core copper leads and one week build time the SC Tchaikovsky stands out as a marvel of sight and sound.

Ultra Pure Ohno Continuous Cast copper wire is considered to be some of the finest wire in the world.Extremely natural sounding without any hints of edginess or graininess.
The manufacturing process of wire starts with molten copper being formed into long rods or bars. These bars are then drawn through a small orifice that is sized to produce the required gauge of wire. Conventional high purity copper wire has 1500 grains per foot of wire. The grain count is significant because these juncture points compromise the transmission of audio signal down the wire. Oxygen Free High Conductivity (OFHC) wires has an improved formation, with a count of 400 grains per foot.
In 1986, Professor Ohno from the Chiba Institute of Technology developed a continuous casting process for wire (OCC), which resulted in revolutionary improvement in the structural formation. The Ohno method uses heated molds, which controls the length of time that the molten copper cools down in. The rapid cooling time of the conventional casting process is responsible for the fractured grain structure; which results in an inferior end product. Wire drawn from OCC ingots will contain a single copper grain, which can be over seven hundred feet in length. A single grain wire has all the desirable properties for signal transmission, and is remarkably durable. Because of its characteristics of single crystal, unidirectional, free of impurity, flexible fatigue-resistance, corrosive-resistance, low electric resistance, none-crystal boundaries, rapid transmissibility, perfect in structure, and easy to process, all make it an ideal material for making rapid transmission lines.
