The TUBULUS Argentus USB Cable V3 is based on pure silver conductors. These solid core conductors are surrounded by mainly air, because (next to a vacuum) air is the best dielectric.
The 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 power conductors are physically separated from the audio conductors. With this construction there are 2 layers of thick copper shielding separating the power and audio conductors.
The TUBULUS Argentus USB Cable V3 is also available as a dual head version, which has separate usb-a plugs for power and audio. Also are the powerlines equipped with RF-filtering.
TUBULUS Argentus USB 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 USB CABLE?
A high end USB cable may sound like nonsense. After all it’s just 1’s and 0’s it has to transport. Any USB 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 USB cable like the TUBULUS Argentus can make great improvements in sound quality.
