Price per metre. The cable is supplied in one piece in the quantity purchased.

Available colours: Light Blue, Dark Grey or White selectable from menu.

The SUPRA Classic 2.5 in white, light blue or dark grey. Extremely flexible 2.5 sqm two-core cable with tinned OFC copper multi-strands with a purity of 5N, i.e. greater than 99.999%. The insulation jacket is a special ionically stable PVC that minimises corrosion of the tinned surface and ensures excellent acoustic performance. By reducing the skin effect and current jumps between the wire surfaces, the tin contributes to improved sound quality.
This range covers all hi-fi applications from low power systems (such as rear speakers in home theatre systems) to high power systems with long cable lengths.

The conductors are individually tinned (with pure tin) OFC copper in such a way as to minimise the skin effect by acting as a semi-Litz-type cable.
Furthermore, this tinning process (not silver plating!) helps to limit conductor jumps, thus transforming the multi-strand cable into a kind of solidcore (single conductor).
Supra claims that the advantage of pure tin over silver lies in the fact that copper and tin ‘mix’ together rather than creating a kind of diodic ‘barrier’ like that between copper and silver. In addition, pure tin protects OFC copper from oxidation.

The technical specifications of the CLASSIC 2.5 (2.5 are the mm2 cross-sectional area) state a resistance of 6.8 Ohms per km (kilometre!) and an inductance of 0.45 µH per metre.
