The TUBULUS Argentus Xs Umbilical Cable is a high end umbilical cable especially made for the Pass Labs Xs series. This cable is based on huge high quality silvered copper conductors. These are solid core conductors to prevent strand interaction, which is a major source of distortion.
The silvered conductors are surrounded by mainly air, because (except for a vacuum) air is the best dielectric. This air insulation is made possible by our tube construction, which can only be made by hand.
To preserve signal integrity the conductors are individually shielded. The TUBULUS Argentus Xs Umbilical Cable is also equipped with a very thick copper braid shielding to prevent electrical noise entering the cable. Which leads to a 100% coverage. To complete this shielding the Xs umbilical cable is finished with high quality aluminum Neutrik NLT8FX Speakon plugs.
All this leads to a very powerful and neutral umbilical power cable, which brings lots of tranquility, dynamics, detail and defined bass!
TUBULUS Argentus Xs Umbilical Cables are made for Pass Labs Xs amplifiers such as the Xs Preamplifier, Xs Phono, Xs 150, Xs 300.
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.

TONE Magazine –
In the case of the Tubulus Argentus Xs umbilical cable, this has been the easiest cable review I’ve ever done. While some of the online cognoscenti make outrageous claims for and against various cables, some of which cost as much as a nice pre-owned BMW M4, the Tubulus umbilicals offer out of this world value. At about $800 USD, in the context of a $38,000 preamplifier, or a $45,000 phonostage, this is a 2-3% upcharge. Normally I would say the cost is noise, but in this case, it’s the absence of noise that is so exiting. The Tubulus cables do not change the tonal balance in my system at all, and I like that. What they do accomplish is to lower the noise floor further and increase resolution. Also, the Tubulus cables don’t need much break in. They sounded excellent at plug in, and slightly smoother after a few days. A hallmark of a high-performance audio system is the way loud sounds smoothly and gently transition to quiet ones, and then off to nothing. This is another area I heard dramatic improvement with the Tubulus cables, digital playback sounds more like analog in this context. Everything auditioned has more texture, with more space between the notes than before. I am definitely buying the review pair, and ordering another pair for the XS Phono. That being said, I’m happy to award the Tubulus XS umbilical one of our Exceptional Value Awards for 2020.
I did not really believe that just a different “umbilical cable” would make a significant difference in my fantastic Xs300. Well, it really does. Even tighter bass, more soundstage, more definition. And audibly so. Highly recommended.
