The TUBULUS Argentus USB Cable V4 is based on pure silver conductors. These are solid core conductors to prevent 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. This air insulation is made possible by our tube construction, which can only be made by hand.

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 power conductors are physically separated from the audio conductors. With this construction there are 4 layers of effective shielding separating the power and audio conductors.

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 TUBULUS Argentus USB cable V4 is finished with shielded plugs which are soldered with silver containing solder.

The TUBULUS Argentus USB Cable V4 is also available as a dual head version, which has separate usb-a plugs for power and audio.

TUBULUS 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 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.

    The Tubulus Argentus USB cable is excellent with awesome price to performance ratio. Comparing to my trusted Shunyata Sigma V1 USB cable at 4 times the price. Your cable fared very well at least I didn’t notice a down grade in sound! Full of information and not aggressive and not thin.

    I’ve tested the Tubulus cables extensively and I’m very impressed. A lot more 3D experience in the music! And with the Tubulus usb cable between my Ubuntu network player and dac, it significantly sounds better than with a standard usb cable. Now it’s really time to say goodbye to my cd player. It’s all just very good, because you can actually hear a live performance instead of the speakers. And that’s just what I’m looking for. So I’m very satisfied with the Tubulus interconnects, speaker cable and usb cable.

    Original Review (Dutch)
    Ik heb de Tubulus kabels uitgebreid getest en ik ben zeer onder de indruk. Een stuk meer 3D beleving! En de Tubulus usb kabel, tussen mijn ubuntu netwerk player en dac, klinkt ook beduidend beter dan een ‘gewone’ usb kabel. Ik zeg nu echt vaarwel naar de cd speler. Het geheel is gewoon erg goed, want je hoort steeds meer een live gezelschap en steeds minder de speakers. En daar is het mij uiteindelijk allemaal om te doen. Ik ben dus zeer tevreden over de Tubulus interlinks, luidsprekerkabel en usb kabel.

    I received the Tubulus USB cable in good order.
    Apart from the fact that it looks good, it sounds warm and detailed.
    Definitely worth the investment.

    In my search for a high-end USB cable I had on trial for a week the AudioQuest Carbon, AudioQuest Coffee and Tubulus Argentus USB cable. Before I listened to them, I’ve let them play for a night.

    Listening test AudioQuest Carbon :
    In comparison with a standard USB cable, the sound was a lot more open, more details .

    Listening test AudioQuest Coffee:
    Here it began to sound really interesting. All just a bit more of everything (like effects in the music). Break in time was the shortest.

    Listening test Tubulus Argentus:
    Initially the same as the Coffee only it seemed as if the high tones were less present. What didn’t bother me. Gradually it became clear that the micro detail in the music was easier to hear and that there were certainly high tones but with more tranquility. It was also like being there with the performing artists.

    And when I played the “2 meter sessions” CD the moment came for me that I knew “this is it”! The 3D-soundstage or how you may call it was very special, Here the Tubulus really stood out from the rest. I’ve also listened to the Buena Vista Social Club with the Coffee and Argentus and the conclusion was the same for me. With the Tubulus Argentus, it’s like being in the same space as the performing artist. Which is great! The sound of the piano has also more depth.

    Conclusion :
    I think I have been clear enough, My choice is
    the Tubulus Argentus USB cable!

    Original Review (Dutch):
    In mijn zoektocht naar een high-end USB-kabel heb ik een week lang de Audioquest Carbon, Audioquest Coffee en de Tubulus Argentus USB-kabel op proef gehad. De kabels heb ik eerst een nacht laten inspelen voordat ik ging luisteren.

    Luistertest met de Audioquest Carbon:
    In vergelijk met een standaard USB kabel was het geluid al een stuk opener, meer details.

    Luistertest met de Audioquest Coffee:
    Hier begon het geluid echt interessant te worden, alles net even iets meer.(effecten in de opnamen). Het inspelen was hier wel het korts nodig.

    Luistertest met de Tubulus Argentus:
    In eerste instantie hetzelfde als de Coffee alleen iets minder hoog. Wat ik op zich niet erg vind. Langzaam werd duidelijk dat het micro detail in het geluid makkelijker te horen was en dat het hoog er zeker wel was maar met meer rust. Het was ook als of je net iets meer bij de optredende artiesten aanwezig bent.

    Na verloop van tijd was ook de CD van de “2 meter sessies” aan de beurt en hier kwam voor mij het moment “dit is het helemaal”. De 3D weergave of soundstage of hoe je dit
    verder wil benoemen was erg bijzonder, hier sprong de Tubulus er echt
    met kop en schouders boven uit. Ook met de Buena Vista Social Club heb ik de
    Coffee en de Argentus een paar keer achter elkaar beluisterd en de conclusie
    was voor mij hetzelfde. De ervaring dat je in de ruimte staat als of je
    aanwezig bent is bij de Tubulus Argentus geweldig! Ook de klank van de piano heeft meer diepgang gekregen (aanslag en naklank).

    Ik denk dat ik wel duidelijk genoeg ben geweest. Mijn keuze is geworden
    de Tubulus Argentus USB-kabel!

    I was quite sceptic about special audio USB-cables. But after trying the Tubulus Argentus USB-cable I realize it’s no fable. This cable made the biggest difference a cable has ever made in my audio setup! And I have heard many. Everything fell into place. The sound is very clean and revealing with a great stereo image and depth.
