Very clear and detailed USB cable, with a realistic, transparent, open and width stereo image!
Review quote: “…With the TUBULUS Argentus Black USB cable, it’s like being in the same space as the performing artist. Which is great!…”
• Pure silver conductors
• Solid core conductors
• Partially air insulation
• High twist rate EMI cancellation
• Special thermo-process
• 2 layers of thick copper shielding
• Fully isolated power conductor
• Special RF-filtering on power conductor
The TUBULUS Argentus Black – USB cable is based on pure silver conductors, because silver is the best electrical conductor of all metals and silver oxides are no problem for audio signals. The solid core silver conductors are surrounded by partially air, because air is the best dielectric (except for a vacuum) of all. To enhance the good qualities of silver the conductors are treated with a special thermo-process (which is not cryo). The signal conductors are twisted with a high twist rate for the purposes of cancelling out electromagnetic interference (EMI) from external sources and are placed behind 2 layers of thick copper shielding. To preserve signal integrity the power conductor is fully isolated from the signal conductors and equipped with RF-filtering, which is unique!
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 Black can make great improvements in sound quality.
TUBULUS USB cables are hand crafted with love, expertise and devotion with no excess decoration or luxury packaging and therefore true value for your money!
