Description
The TUBULUS Concentus ethernet cable is based on high quality pure silver conductors. These are semi-solid concentric conductors to minimize strand interaction, which is a major source of distortion.
The conductors are surrounded by air, because (next to a vacuum) air is the best dielectric. The use of air insulation in a ethernet cable is unique.
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 cancelling out electromagnetic interference (EMI).
To preserve signal integrity the conductors are individually shielded. An overall shield and thick copper braiding completes this shielding so that a 100% coverage is guaranteed.
To prevent radio frequency interference (RFI) from modulating the ground reference skin effect filtering is applied to the shield. This is a very effective way to eliminate noise and RFI before it reaches the component.
The high quality RJ45 plugs are also shielded and soldered with silver containing solder. All this makes it an unique ethernet cable.
The TUBULUS Concentus ethernet cable is available in a 100Mbps and a 10Gbps version. Of course the high speed 10Gbps is faster but the best result for audio streaming is achieved with the 100Mbps version. And as known is 100Mbps more than sufficient for all audio formats.
TUBULUS Concentus ethernet 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 ETHERNET CABLE?
A high end ethernet cable may sound like nonsense. After all it’s just 1’s and 0’s it has to transport. Any ethernet 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 ethernet cable like the TUBULUS Concentus can make great improvements in sound quality.
