Supra Ply 3,4mm2 2 x 3,0m m/bananplugger

2x3.4 mm² sandwich design. Ply combines low induction and tin plating which provides for explosive dynamics. Ply is a multi-award winner and one-of-a-kind quality cable from SUPRA. Pre-terminated with CombiCon crimp connectors providing a 6mm threaded body.

Crimping means pressing together under very high pressure. A properly crimped joint brings the materials together in an airtight, homogeneous and electrically ”invisible” joint that is superior in this application. All factory crimping is performed using dedicated machine tools.

SUPRA Ply - A Logical and scientific Design
The square shaped design reveals the full potential of dynamics and transients of your Hi-Fi system Further, it reduces interference and interaction distortion. Tin plated.

Audio cables’ performance is initially determined by their loop resistance (R) & inductance (L) & shunt capacitance (C). For most speakers, R & L must be low, but capacitance value, C doesn’t matter as speakers already act as large cap loads. But simply using larger wire makes R low, at the expense of an increasing ratio to L with musically unacceptable effects.

Ways to make inductance L low also with low resistance, include tapes, either stacked or arranged in ribbons. But these types are impractical to fit to nearly every speaker connector without discontinuities, & are stressed often unsightly when bends are required in real installs & also aren’t suited to mobile uses.Litzing with multiple, insulated conductors is more practical, but quality Litzes are expensive and termination not easy. Other types are gross, like industrial pipes, unsuited to many domestic spaces. Simplistic fat conductors’ rising impedance (due to L) of +6dB/octave is further raised by internal eddy currents causing ’Skin effect’, like ’the square root of inductance’, adding. +3dB/oct, to the L-reactance slope. For typical cable runs, net inductivity is such that performance in heavy plain conductors is measurably affected with steady signals just above 1kHz.

Cables with copper or silver stranded conductors suffer from complex oxidation. The semi conductive ’diodes’ between the strands aren’t seen by steady tests, but look like a high capacitance to music signals. This causes energy storage/release cycles, that regular tests miss, yet which is audible with music. This problem is also describable as the electron flow being ’trapped’ inside strands & twisting away from the direct route.

SUPRA PLY is a large section, low resistance cable, overcoming skin effect & transient distortion, using pure tin plating. Tin melds to copper without any diodic barrier, & also protects the copper from common corrosions - ideal for outdoors & 12 volt. Most audiograde cables’ conductors are damaged by contamination, by plastic out-gassing, from the impure atmosphere, & liquid spills. Some are protected but only by a thin coating that’ll one day crack with use and age. Neatly, oxidation forming on Ply is sonically benign.

Other advantages when installing, PLY’s rectangular conductor is readily circularised for insertion into receptacles of most regular connectors. Square outer profiling suits most housings too - unlike ribbons, tapes & litzes. PLY is readily coiled, more like thinner, basic cables - making it friendly in temporary setups.
