The TUBULUS Concentus i2s cable is specifically designed for i2s signal transport and is based on high quality pure silver conductors. These are solid core conductors to prevent strand interaction, which is a major source of distortion.

The conductors are of various diameter and individually insulated by air. Which is unique! We use air insulation because (next to a vacuum) air is the best dielectric.

The pure silver conductors are treated with a special thermo-process and are twisted with a high twist rate for the purposes of cancelling out electromagnetic interference (EMI).

To preserve signal integrity the conductors are individually shielded. An overall screen and copper braid completes the triple shielding with a 100% coverage. The TUBULUS Concentus i2s cable is terminated with high quality shielded HDMI or RJ45 plugs.

All this makes it unique and the best i2s cable in the world.

TUBULUS Concentus i2s cables are hand crafted with love, expertise and devotion with no excess decoration or luxury packaging and therefore true value for your money!

A high end i2s cable may sound like nonsense. After all it’s just 1’s and 0’s it has to transport. Any hdmi cable can do that. But those 1’s and 0’s have to be transported by a bunch of electrons traveling through a wire and electrons don’t know if they are ‘analog’ or ‘digital’. In fact, all electrical signals are analogue.

However, the digital signal is different; it is a pulse train, a square wave instead of a sine. But a perfect square wave doesn’t exist, because transition from one to zero requires time. So there is always a rise/fall time and the edges of the square wave will be rounded. In fact the square wave is a kind of trapezium with rounded edges.

Depending on the quality of the cable, the corners of the square wave will round off to a greater or lesser degree and the “flat” portions of the wave will become uneven as well. Small changes will make it harder for the receiver to detect the exact moment the rise or fall is happening. This will induce jitter. And if the changes become too big, the receiver will not even be able to reconstruct the logical 1’s and 0’s properly.

This is why a high quality i2s cable like the TUBULUS Concentus can make great improvements in sound quality.
