The TUBULUS Libentus i2s cable V3 is specifically designed for i2s signal transport and is based on high quality silvered copper conductors. These are solid core conductors to prevent strand interaction, which is a major source of distortion.

The silvered copper conductors are individually insulated by air. Which is unique for a i2s cable. We use air insulation because (next to a vacuum) air is the best dielectric.

The conductors 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 braiding and high quality shielded HDMI plugs completes this shielding so that a 100% coverage is guaranteed.

The TUBULUS Libentus i2s cable V3 is compatible with all i2s devices and also with the Auralic Lightning Link.

NOTE: If a ‘standard’ HDMI or RJ45 cable doesn’t work in your setup a Tubulus i2s will not either. Then you might need a i2s cable with custom pinout.

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 Libentus can make great improvements in sound quality.
