SUPRA’s flagship. Sword is a patented cable. The secret is the bifilar wound litz conductors, each comprising 24 individually insulated wires.
The bifilar winding is built with 12 of these wires helically wound in one direction and 12 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. Therefore Sword behaves as a non-inductive and phase stable cable. The difference in phase shift from 500Hz to 100kHz is only 0.002 deg. This allows for perfect timing. Patent holder: Johnny Svärd.
What does it sound like?
Supra Sword passes the most complex music transients without any deformations. Signal delay is the same at all musical frequencies. Therefore it vanishes, giving a clear 3-dimensional presence, a sure sign of the highest fidelity.
Sword 2x3m
Owing to the special construction with two opposite wound wire groups which cancel each other’s fields, the termination quality is very critical.
The termination is done with strong, gas tight crimping, so the joined metals are fused into one unit. This is more pure and secure than any soldering.
Sword is available in standard length of 2m, 3m and 4m pair, delivered in a Mahogany wood case.
Termination: Spade/Banana/BFA combination connector.
Customised lengths available on order.
The Sword Combi Connector
Sword comes with crimp-fastened screw-adaptors, and a set of connectors that can be screwed onto these. The pictures show Spades and banana/BFA connectors, as well as the Spade replaced with Banana/BFA directly screwed onto the adaptor. All connectors are included in a Sword kit.

Sword Jumper 28 cm pair
Fixed Spade termination, not the CombiCon, i.e. not replacable with Banana connectors. This is a bridge connection for loudspeakers with double inputs (Bi-amp). Tom Frantzen of the German magazine STEREO created the idea of this product.
The usual strap connections between the loudspeaker terminals are good examples of how a jumper should NOT be designed. They make the most high inductance connection by means of the wide distance between the conductors. In order to overcome this weak link the SUPRA Sword Jumper was developed.
