(1261 Zeichen (mit Leerzeichen) / 195 Wörter)The unique AIR technology from in-akustik impressively demonstrates what high-end speaker cables can achieve in terms of sound - thanks to selected materials and sophisticated cable architecture. For the further development of its AIR cable series, the German manufacturer has intensively worked on perfecting the conductor material now: The flagship Reference LS-4004 AIR Pure Silver and the Reference LS-2404 AIR Pure Silver have got conductors made of pure silver. Although copper is a very good conductor in the corresponding purity, the best conductive material under real conditions is silver - with a conductivity around six percent better than copper. However, the precious metal is about 100 times more expensive. That is why in-akustik has decided to deliberately disregard the costs and instead consistently expand the limits of what is feasible once again. The result is a combination of the legendary AIR Helix construction and the associated air insulation (the best possible dielectric in addition to the vacuum) with the best conductor material in the form of pure silver - instead of, for example, alloyed or merely silver-plated wires. The high quality sound of the outstanding AIR-Silver cables now sets new standards in the high-end sector.

For the further development of its AIR cable series, the German manufacturer has intensively worked on perfecting the conductor material now: The flagship Reference LS-4004 AIR Pure Silver and the Reference LS-2404 AIR Pure Silver have got conductors made of pure silver.
The AIR technology is a milestone in in-akustik's more than 40-year company history and is causing a worldwide sensation in the hi-fi industry. The approach sounds relatively banal: Physical losses must be minimized in order to transmit the original music signal as unchanged and neutral as possible. And AIR technology comes closer than ever to lossless transmission. It leads to significantly better sound reproduction, which is not only subjectively audible, but also objectively measurable. The insulation or dielectric of the AIR cables is almost perfect thanks to the air insulation and hardly influences the sound any more. The construction, dimensions and arrangement of the conductors are optimized and fully exploit what is physically feasible.
In order to set another sonic highlight on this basis of audiophile perfection, the developers at in-akustik have now focused on the conductor material of the cables. Copper of the appropriate purity is a very good conductor. A superconductor that does not resist the current would be perfect. However, the superconducting properties of the material require low temperatures of at least minus seventy degrees. Silver is currently the most conductive material under real conditions. At 61.35 S/m (Siemens per meter), its conductivity is about six percent better than that of copper. However, the precious metal is about 100 times more expensive.
Theoretically, the copper cross-section could simply be increased. However, this would require considerable compromises in cable construction, which would ultimately have a negative effect on the sound. That is why in-akustik has decided to deliberately disregard the costs and instead consistently expand the limits of what is feasible once again. The result is a combination of the legendary AIR Helix construction and the associated air insulation (the best possible dielectric in addition to the vacuum) with the best conductor material in the form of pure silver - instead of, for example, alloyed or merely silver-plated wires. The high quality sound of the outstanding AIR-Silver cables now sets new standards in the high-end sector.
AIR helix from in-akustik
The AIR Helix construction is absolutely unique. In order to come as close as possible to perfect air insulation, in-akustik has developed special clips. Inside the cable, a large number of these clips form the supporting framework, which keeps the signal conductors helically free in the air and guides them through the cable at a defined distance. The flexibility of this construction is achieved with the LS-4004 AIR Pure Silver by joints in the clips.
Of course, the conductors themselves also play an important role. They consist of 24 high-purity silver wires braided onto a PE core. A wafer-thin varnish layer on the wires prevents eddy currents within this "Cross Link Super Speed" waveguide. It protects the wires from oxidation additionally. By far the largest currents in the entire audio chain flow through the loudspeaker cable. Some of the correspondingly strong magnetic fields are compensated in the conductors themselves by the bifilar arrangement of the wires.
The LS-4004 AIR Pure Silver and LS-2404 AIR Pure Silver are the optimal solution for the realization that loudspeaker cables should primarily have a low inductance: Due to the two-layer arrangement of the double layer multicore, the magnetic fields around the individual conductors overlap and neutralize each other. This considerably reduces the inductance of the cable and also the high audio frequencies are transported unhindered and without time delay.
Made in Germany like all loudspeaker and audio cables of the Reference series, the LS-4004 AIR Pure Silver and LS-2404 AIR Pure Silver are completely manufactured in Germany. The clips are assembled by hand with great care at in-akustik’s own on-site factory and the "Cross Link Super Speed" waveguides are threaded in. The resulting AIR Helix then also receives the PE network jacket by hand, before the rhodium-coated plugs are installed and the cable is tested for proper function.

„Kompromissloser Klang“ — so kurz lässt sich beschreiben, was die in-akustik GmbH & Co. KG mit Sitz in Ballrechten-Dottingen bei Freiburg seit der Firmengründung 1977 antreibt. Sie gehört als ein Unternehmen der Braun-Firmengruppe zu den Top-Unternehmen der HiFi- und Musikbranche: Mit eigenen Independent-Plattenlabel und als führender Anbieter von HiFi- und Videokabeln. Seit Juli 2014 vertreibt in-akustik die Lautsprecher der Schweizer High-End-Schmiede Piega in Deutschland, seit Januar 2016 zudem die Audio- und Heimkino-Komponenten der legendären schwedischen Marke Primare. Seit 2018 wird das klangstarke Lieferprogramm durch die unerschütterliche Gerätebasis Stoic ergänzt — für Wand, Möbel und Boden. Darüber hinaus bietet in-akustik Systeme für intelligente Haustechnik an, die ebenso im privaten wie im öffentlichen Bereich eingesetzt werden kann. Mit viel Liebe und Leidenschaft bietet in-akustik stets exzellente Qualität und lässt nicht locker, selbst das beste Kabel, die perfektesten Lautsprecher und die schönsten Medien noch verbessern. Seit 2019 werden die Kopfhörer der amerikanischen Marke Koss in Deutschland vertrieben. Die Umgebung der Rheinebene und des Kaiserstuhls, des Schwarzwaldes und der Universitätsstadt Freiburg aber gibt den engagierten Mitarbeitern die Muße, in Ruhe am kompromisslosen Klang zu tüfteln.
“No compromise in sound” — this is how you can describe what in-akustik GmbH & Co. KG with its headquarters in Ballrechten-Dottingen near Freiburg since the company was founded in 1977.
