REFERENZ NF-2404 AIR PURE SILVER RCA (1.5m)

Stereo Cable [2xRCA M - 2xRCA M]

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 we have 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.

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

If you take off a sweater with a high synthetic content it crackles and sparks. The reason for this is that the integrated plastic material stores electrical energy, which is then discharged again. The same happens in the insulation material of a cable. It „absorbs“ electrical energy like a sponge and then releases it again. With an audio cable, however, these are parts of the audio signal. A dimension for this is the cable capacity, i.e. the unwanted storage capacity of the cable. While capacitors are supposed to store energy and have a correspondingly high capacity, the capacity of the cable should be as low as possible. It significantly influences the transmission characteristics through losses and also leads to interactions with the connected electronics. The ideal solution is therefore an air insulation such as the one implemented with the Air-Technology, as this separates the „capacitor plates“ of the cable and thus reduces the capacitance.

Just like all speaker and audio cables from our Reference series, the NF-2404 Air Pure silver are entirely manufactured in Germany. The clips are meticulously assembled by hand at on-site factory in Germany. The resulting Air Helix design then receives a PE network jacket before the finish cable is subjected to a thorough and final inspection.

• Low longitudinal inductance resulting from braided lacquered conductors
• Diameter: about 25mm
• PE network jacket preventing micro-vibrations
