Supra Sword Loudspeaker Cables


SKU: N/A Categories: ,


The Supra sword speaker cable is one of the best speaker cables in the world, irrespective of price.

Take a bunch of Swedish electrical engineers who also happen to be a bit nerdish when it comes to high fidelity and ask them to design a cable made of commercially available sonically benign materials, physically laid out to counteract the malignant electrical behaviour and not to use mystery boxes, batteries or cryogenic treatment of 9N copper.

Completely transparent is perhaps a worn-out cliché but is still what most users and testers agree on. The secret? The bifilar-wound litz conductors comprising 24 individually insulated strands per pole, 12 wound in one direction, the remaining 12 in the opposite, resulting in magnetic field cancellation and very low inductance. Further, the litz wound and individually insulated strands cancels the dynamic skin-effect. The Sword behaves as a non-inductive and in-phase cable through the entire audible frequency spectra. The only thing not cancelled is the sound, allowing you to hear every little note of the music, at full dynamics.

The Supra Sword range of cables are built and terminated at the factory in Sweden. We have a lot of experience in re-terminating this cable for those customers requiring shorter lengths due to a room change or damage.

I have demo cables available to try out and I encourage you to test them in your own system.
