SUPRA Sword Excalibur – Simply the best!
For 2 years Sura have been trying to develop the ultimate speaker cable, the result was Sword Excalibur. The goal was to make the world's best speaker cable, no compromises or shortcuts. Every part of the design must be of top quality but still affordable and as always manufactured in Sweden. Bifilar-wound litz conductors, PE insulation, twisted and shielded for minimal interference, CNC-milled cable splitter with ground connection, XL-Annorum earth conductor, solid copper connectors with Rhodium plating. The crimp bodies are specially designed for Excalibur, the conductor is twisted into the crimp body (like a F-connector) for maximum bending strength. The de-insulated Litz wires are then crimped mechanically for a perfect and airtight cable connection. The connector body is provided with a M6 connection, which enables any connection with Rhondium-plated spades or banana pins. The ground connection with XL Annorum conductor is in standard 30cm and also it is equipped with specially adapted and rhodium plated Combicon connectors.

We have previously modestly stated that our standard Sword is one of the best cables available, regardless of price or manufacturer. Sword Excalibur takes a few more steps towards an almost total transparency, still the only word that correctly describes this patented "high-end" speaker cable.

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. Patented cable design, manufactured in Ljungskile, Sweden!

What does it sound like?
The best way to describe it is nothing, but that is hard to imagine, so we will try to explain. Sword will maintain the true signal put out from your Hi-Fi system, giving a completely transparent transition from amplifier to speaker. You will hear the music, nothing more, nothing less.

We only sell Sword pre-terminated!
The reason is that the transition between the cable and connectors is very critical. In order to maintain the superior cable and contact properties, we have reached the conclusion to keep this in-house. We crimp the unit together at high pressure, making a perfect, air tight, joint.

It is supplied in an exclusive black wooden Box comprising both Rhodium plated banana and spade connectors. We simply could not resist an extra treat for this remarkable cable.
