Supra’s flagships, the Sword Interconnect and the Sword Loudspeaker cable, are of a patented cable design. The secret is the bifilar wound litz conductors, each comprising a number of individually insulated wires. The bifilar winding is built with 6 of these wires helically wound in one direction and 6 in the opposite direction. This divides the magnetic field into opposing directions resulting in self-cancellation. Because Sword’s conductors comprise a number of insulated wires, dynamic skin effect is cancelled. Sword behaves as a phase stable cable. The difference in phase shift from 500Hz to 100kHz is only 0.002 deg. This grants for a perfect timing.
Supra is one of the only European cable brands that actually manufactures its own cables, to its own specifications, in its own factory (in Sweden). For a long time now, it has been producing very worthy, fine sounding interconnects and speaker cables, in any colour you like as long as it’s pale blue. The new Sword is – shock, horror – semi-translucent, ermm pale blue. Those crazy Swedes!
In a high end cable market dominate by the likes of Chord Company and Van den Hul, it’s a difficult call for a less well known name such as Supra, but the Sword is good enough to take on anything. Of course, each different variety of cable has its own character, but the Supra’s will win many friends. It is exceptionally neutral, with just a touch of dryness noticeable against the likes of the (much more expensive) Chord Indigo. Bass is seriously strong and clean, but there’s no artificial bloom. Midband is translucent, with a light, airy, spacious, widescreen presentation, and treble gloriously crisp and delicate. An essential audition at the price, an ideal for taming a splashy, loose or wayward high end system.
