Sword ISL

Our best analog interconnect cable ever; the flagship of Supra. Sword-ISL is a Supra RCA-8 jubilee connector pair designed for single-ended analog applications.

SUPRA Sword Interconnect - High End

The success of the Sword speaker cable gave us the idea of ​​developing a connecting cable based on the same patented concept. The cable works as a perfect signal carrier without the side effects of traditionally designed cables, which have severe frequency response and phase shift problems.

Sword preserves signal integrity with almost immeasurable warping due to our freedom and ability to master the electrophysical layout, rather than compensating with mystery boxes and batteries. Regardless of the price, the Sword series is hard to beat. Available in an unbalanced (RCA) and a balanced (XLR) version.

How does that sound?

Supra Sword doesn't sound at all. Supra Sword transmits the complex musical signal of an infinite number of sine waves and an infinite number of levels without any distortion between the output of the source and the input of the receiver. No part of the music suffers a delay (phase shift), so the timing of each note before and after is exactly the same.

When every other hi-fi device in the system is able to reproduce the timing and preservation of the sound of the recordings just as correctly, the speaker placement and the acoustics of the listening room are optimal, the result is so lively that one really can imagine being in the studio with the musicians.

The sword's lack of electrical properties ensures complete transparency. It's sometimes difficult to distinguish a transparent cable from one with an apparent "sound lift" that emphasizes certain notes. But you'll quickly notice that if every album in the music collection has the same sound style and not the unique signature of each album/melody.


The figure shows the structure of the cable. In each polarity conductor there are twelve individually insulated strands forming two layers. The inner six strands are spun around an inner core and have a high pitch in one direction, the outer six strands in the opposite direction, separated from the inner layer by an extruded insulating layer. This orientation of the strands effectively counteracts any unwanted electrophysical properties, so that all audible frequencies are evenly distributed inside and there is no open window for harmful noise to penetrate. The music is let through sounding exactly the same. This is what distinguishes a completely transparent cable.
