SUPRA Sword Jumpers – Replaces the original jumpers
Want to hear your speakers true potential? Not hard to guess the answer to that. Very often, but not always, is the original jumpers connecting high and low frequency register of substandard quality. If you invested in a pair of good speaker cables, you end up choosing back and forth between the two or three pair of speaker connectors available. Everytime, you find the other registers suffering and we recommend that the thin sheet metal jumpers supplied from factory is replaced with our Sword Jumpers if you desire a really seamless transition.
How is it possible, that this cable, performing so good, is so affordable? The answer is that we are Swedes and we have a different posture to designing and prizing. In spite of the affordable price, we are proud to say that the Sword is one of the best speaker cables there is. If you take a bunch of Swedish engineers, hifi nerds as well, and ask them to design a cable of sonically benign materials, physically laid out to counteracting the malignant electrical behavior and finally ban any mystery boxes, batteries or cryogenic treatment of 9N Copper, you end up with the Sword. And what is more of a problem for our competitors, it does not need to cost a fortune.
Completely transparent, perhaps a worn-out cliché, is still what most users and tests agree on. 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, individual insulated strands cancels the dynamic skin-effect. The Sword behaves as a non-inductive and in-phase cable through the entire audible frequency range. The only thing not cancelled is the sound, allowing you to hear every little note of the music.
So, finally, we apologize for the low price and hope you might consider to give it a good try anyway?
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.
The Sword Jumpers is supplied with fixed spade (fork) connectors.
