Description
The TUBULUS Concentus Digital Interconnect 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 silver conductors are individually insulated by air. We use air insulation because (next to a vacuum) air is the best dielectric. This air insulation is made possible by our unique star septet tube construction, which can only be made by hand. The conductors are positioned in a star septet configuration to maximize noise rejection.
The Tubulus Concentus Digital Interconnect consists of various diameter conductors because every diameter has its own musical character. With a special thermo-process the silver conductors are restructured at a molecular level to reach a quality close to mono crystal silver.
The TUBULUS Concentus Digital Interconnect is also equipped with 2 layers of very effective shielding to prevent electrical noise entering into the cable. This shielding has a 100% coverage.
The TUBULUS Concentus Digital Interconnect is available with high quality silvered RCA plugs (S/PDIF) or XLR plugs (AES/EBU), which are soldered with silver containing solder.
TUBULUS digital interconnect cables are hand crafted with love, expertise and devotion with no excess decoration or luxury packaging and therefore true value for your money!

WHY BUY A TUBULUS DIGITAL INTERCONNECT CABLE?
A high end digital interconnect cable may sound like nonsense. After all it’s just 1’s and 0’s it has to transport. Any 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 digital interconnect cable like the TUBULUS Concentus can make great improvements in sound quality.
Clemens –
After 48 hours of playing I seriously listened to the Concentus digital interconnect. It indeed has a fuller midrange and a tighter low end compared to the Argentus. But it also has a more spatial image and more texture. The Argentus is good, but the Concentus plays a class above. Really great!
