The TUBULUS Argentus Jumper Cables are based on high quality pure silver and silvered copper conductors. These are solid core conductors to prevent strand interaction, which is a major source of distortion.
The conductors are individually insulated and 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.
The Tubulus Argentus Jumper Cables have various diameter conductors. Because every diameter has its owm musical character. The pure silver conductors are also treated with a special thermo-process (not cryo) to reallign the monocular structure.
The TUBULUS Argentus Jumper Cables are available with high quality gold plated spades or banana plugs, which are soldered with silver containing solder.
TUBULUS Argentus 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!**

WHY USE AIR INSULATION
Most audio wire has extruded insulation, where the insulation material is in intimate and immediate contact with the conductor along its entire length. This forms the dielectric of the wire, which has a tendency to absorb and release energy to and from the conductor. The occurrence of this phenomenon produces negative sonic affects. Dielectric constant measurements are used to determine the ability of an insulator to store electrical energy. Common insulator materials and their dielectric constants are Teflon (2.1), polyethylene (2.25) and polyvinyl chloride PVC (3.18). The best practical dielectric is air, which has the near-perfect lowest dielectric constant (1.00059) next to a vacuum (which has a perfect dielectric constant of 1). That’s why TUBULUS uses air insulation.

My new handmade speaker jumpers and i2S cable from Dutch Tubulus arrived on Monday 24th of January. Posted Friday and received Monday – thanks to DHL! I immediately connected the cables to the music system, turned up the volume and I almost fainted with surprise. I was expecting some improvement, but not close to what came out through the speakers. I will try to describe what I heard:
It is as if transparency has been added over the entire frequency range, which means better dynamics and tonal reproduction. Even with open eyes, it is as if the speakers have disappeared. The soundstage has opened up even more, and the elements I have previously complained about (high frequency noise) have disappeared. Cymbals sound like real instruments, made of precious metals. Female voices are full-bodied and clean, even when it comes to pronunciation of the critical T, ST and SH sounds (sibilance).
I can only dream about how it will sound when the cables are completely run in. The i2S cable connects the DDC and DAC and transports the i2S signal, after it has been converted from USB. Ideally, the Denafrips DDC should be an integrated part of the DAC. With the new i2s cable, it sounds like I got a much more expensive DAC!
Now, after almost 2 weeks with about 100 hours of use, it seems that the Concentus i2S delivers maximum, and the all-over cleaner sound especially in the upper register, and better micro dynamics is transferred to the electrostatic panels with renewed musical energy and without any kind of electrical noise or filtering.
I can highly recommend both the Tubulus Argentus speaker jumpers and the Tubulus Concentus i2S / HDMI cable.
