Supra Ply 2 x 3.4 mm2
Supra Ply is a long life multi-award winner and one-of-a-kind quality cable from Supra Cables.
When mangling the braid to thin conductor layers, extruding a thin layer of insulation and then putting them together with the flat sides facing eachother, the capacitance will increase significantly.
An in-depth analysis require some mathematics exercise, so we leave the physical theory here and simply state that two conductors with different polarity laid out with a large mangled side area facing each other, will feel their individual charge, thus acting as a capacitor.
If we just stopped there, we would not gain anything, but the real finesse it that the capacitance will raise at the expense of inductance! And, the capacitance is sonically less significant in the speaker circuitry. Further Supra Ply offers the tin plated strands that reduce the disruptive electron jumps between lead strands resulting in a signal time shift, a very unwanted distortion when the original holographic 3D sound stage is desired.
Once again, Supra Cables design a "simple" yet ingenious cable that because of its physical properties counteracts malignant sonical behaviour, is cost efficient to produce, thus affordable to the customer and allowing for a better sonical experience. Still. Because this is a quite old design.
What we have done recently, presented in a separate section, is an evolution of this concept with an even wider conductor, mangled in a twop-step process, facing each other resulting in a further elevated capacitance, hence even lower inductance (Supra Ply Wide).
Supra Ply is available in a number of configurations, conductor areas, w/o screen, on bobbin or pre-terminated lengths, all with the basic sonic concept and some extra features added.
The shielded version, with the drain wire connected to the negativ lead is also a way to further increase capacitance, improve sonics, but also protect both adjacent equipment from harmful fields and radiations as well as the human aspect, e.g. EHS - electro hyper sensitivity.

The Difference that makes the Difference - for You
Unlike many of todays audio cables, the Ply benefits are proven by repeated measurements and tests nearly all over the world.
The figures 1 and 2 shows our Ply and a generic cable with a wide space between the conductors, a quite common "high-end" design today. We fed both cables with the most challanging signal there is, square wave, representing very high frequencies. Every drum beat, piano fingering, classical music, acoustic jazz, etc, is full of ultra fast transients, best represented by the square wave.
The result speaks for itself. While Ply only show a minor loss, the generic cable dampens the highs up to 20 kHz by a staggering 10 dB! It is a major treble roll-off, clearly audible and will undoubtedly drive the listener to compensate using the tone controls and by doing so further deteriorate sound quality by adding tone control phase shift.
Before purchasing any cable, visit your local Supra dealer and discuss your level of equipment, borrow a couple of speaker cables sets to make a good listening comparison. Anyone searching for that particular live feeling, when music displays the typical dynamic drive, 3D soundstage, clean crisp highs and clean dynamic bass, in fact almost feeling like the beat is imaginary slightly faster, will probably end up with a set of Supra Cables. It is such great fun when music comes to life and your feet will not stop stomping the beat!
