Supra Sword speaker cable
Supra
have developed many ideas for their cables over the past 25+ years since the company's'
founding. And now one of the results of it's investment in Research and Development
is the Supra Sword cable, designed by Johnny Svard (Svard is Swedish for Sword
!!).
Sword is a speaker cable made from 24 conductors - 12 are wound
one way (say clockwise) and the other 12 are wound counter-clockwise. When terminated
(in the factory) great care is taken to ensure that all 24 conductors are in correct
electrical and mechanical contact with the terminations.
This helps to ensure that the cable has absolutely no inductance. And as you may
recall from your school days, with high level signals, inductance has one of the
largest effects on the "sound" of speaker cables (and how they interact
between the output stages of the amplifier and the passive components on the speaker
cross-over network).
By reducing the speaker cable inductance to a negligible amount,
Supra can claim to have a speaker cable that introduces no
effects of its own into the sound of the system. Thereby allowing
the main components of the system to work harmoniously together.
The standard lengths of Sword cable are 2m, 3m, 4m or 5m sets. Other
bespoke lengths can be made to order - expect a 5-6 week delay (due
to Brexit issues, importing into the UK from the EU) for these to
be assembled to order and then despatched to us.
Each set is terminated with Supra CombiCon interchangeable connectors
(a choice of BFA, Banana or Spade connectors are supplied in each
box).
 
For some lengths we can optionally supply Sword with FIXED spade
connectors at both ends - currently only 4m and 5m lengths are available
in this option.
Please also note: Sword is a "single-wire" cable - that
is, if you want to bi-wire, you'll need 2 sets.

in a superb wooden presentation case.
However, this has now been discontinued and new shipments of Sword
are packed in a cardboard presentation box.

Sword Jumpers
Sword can also be supplied as a pair of 28 cm
"jumpers" to connect across bi-wire terminals (and which replace the
inferior sounding gold-plated brass "jumpers" fitted to many bi-wireable
speakers when used in single-wire mode).
Sword interconnects
A matching interconnect cable, terminated with either lockable
phono (Sword-ISL)
or XLR connectors (Sword-IXLR)
is also now available. |
