| Supra Sword Excalibur speaker cable
Sword Excalibur Simply the best
For 2 years we have been developing our ultimate speaker cable.
The result: Sword Excalibur.
Our goal was to make the worlds best speaker cable, with
no compromises or shortcuts. Every part of the design must be
of the highest quality while still affordable and as usual manufactured
Bifilar-wound litz 5N OFC conductors, twisted and shielded for
minimal interference, PE insulation, CNC-milled cable splitter
with ground connection, XL-Annorum earth conductor, solid copper
* The Supra CombiCon CB03-EX crimp bodies are specially designed
for Excalibur, and each conductor is twisted into the crimp body
for maximum bending strength. The uninsulated litz wires are crimped
mechanically for a perfect and airtight cable connection.
* The connector body has a Supra M6 thread, which allows the user
choice of interchangeable rhodium-plated Supra spades or banana/BFA
* The ground connections are 30cm long, using Supra XL-Annorum
conductors, and specially adapted, Rhodium-plated Supra CombiCon
In the past, we modestly claimed that our original Sword was
one of the best cables available, regardless of price or manufacturer.
Sword Excalibur takes a few more steps towards total transparency,
still the only words that properly describe this patented high-end
The secret? The bifilar-wound litz conductors comprise 24 individually
insulated strands per conductor, 12 wound in one direction, the
remaining 12 in the opposite, resulting in magnetic field cancellation
and very low inductance. Further, this reduces any possible dynamic
Sword Excalibur behaves as a low inductance cable whilst maintaining
phase throughout the entire audible frequency range resulting
in minimal insertion loss between amplifier and loudspeaker. The
only thing not cancelled is the SOUND, allowing you to hear every
nuance of the MUSIC, in its full dynamic glory.
The earth conductor should be connected in the source end only
(amplifier side) as follows:.
* To the Earth terminal at the amp (not available on all amps)
* To the Negative speaker out terminal
* Or connect to any of the amp chassis screws.
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.
The standard lengths of Sword Excalibur cable are 2m, 3m, 4m or
5m sets. Other bespoke lengths can be made to order - expect a
4-6 week delay (due to Brexit issues, importing into the UK from
the EU) for these to be assembled to order and then despatched
Each set is terminated with Supra CombiCon interchangeable connectors
(a choice of BFA, Banana or Spade connectors are supplied in each
Please also note: Sword is a "single-wire" cable - that
is, if you want to bi-wire, you'll need 2 sets.

Sword Excalibur received incredibly good reviews by the Swedish
magazine Hifi&Musik, read

A matching interconnect cable, terminated with either lockable
or XLR connectors (Sword-IXLR)
is also now available.
