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 and semi-solid concentric conductors to minimize 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.

With a special thermo-process the silver conductors are restructured at a molecular level to reach a quality close to mono crystal silver. The conductors are also twisted with a high twist rate for the purposes of minimizing 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 which are soldered with silver containing solder. 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! And we offer a MONEY BACK GUARANTEE!** Because TUBULUS cables are made by hand the average production time is about 1 to 2 weeks.

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.

    I’ve used a standard Delock HDMI cable (triple shielding) as i2s cable between the Denafrips Hermes DDC and the Denafrips Terminator 2 DAC. Then I’ve upgraded it to Audioquest Vodka and gained some fine details in the highs, slightly noticeable.

    Then I’ve upgraded to the Tubulus Concentus … it was a mesmerizing experience: blacker background, extreme channel separation (headphone like), more details, wider and deeper scene.

    I’ve Been using the tubulus concentus i2s cable for a few days. It connects the 3d-lab nano network transport to the dac of the same brand. Immediatly, an incredibly wide stereo effect and an instrument rendering finesse that I did not expect. For example the roundness of the saxophone is wonderful. I hear the background sounds of the orchestra as if i was approaching the musicians. I understand that the cable needs quite some playing time to reach maximum result but already this i2s cable is a marvel.

    Received the Tubulus Concentus i2s cable this morning. That was fast! First impression is very encouraging. Seems to be more prominent in the mid-range and more micro details (better timbre and more decay) which is much to my liking.
