• Air insulation
• Handmade concentric tube construction
• Special thermo-process
• Dual shielding with 100% coverage
• High quality plugs


The TUBULUS Concentus Analog Interconnect is based on high quality pure silver conductors. These are solid core and semi-solid concentric conductors to minimize strand interaction, which is a major source of distortion.

The conductors are of various diameter and individually insulated by air. We use air insulation because (next to a vacuum) air is the best dielectric. This air insulation is made possible by a unique concentric 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 TUBULUS Concentus Analog Interconnect is also equipped with 2 layers of very effective shielding to prevent electrical noise entering into the cable. This shielding has a 100% coverage.

TUBULUS Concentus Analog Interconnect cables are available with high quality RCA or XLR plugs, which are soldered with silver containing solder.

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.

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.

    The Concentus Analog Interconnect is wonderfull! It is a big step above the JCT Module one which one was a big step above any other câble I had before including high-end JCT cables….
    I’m able to listen music to lower volume level with the same, sorry, more pleasure (about 6 to 10db lower) with udge of details and how easy it is to follow singers than before.
    it is very clear, detailed, a litte wider 3D image, top realistic, super transparent (more emotions than before and no harshness), and has “REALY NEUTRAL” sound (no sound signature added). I fall in love with these XLR cables.
