Digital-2404 Air Pure Silver (XLR)
The AIR technology is a milestone in our more than 40-year company history and is causing a worldwide sensation in the hi-fi industry.

Our cables of the REFERENCE AIR series have already caused a sensation in the world of high-end connections: "It was the best cable that ever acted between amp and speakers!" (AUDIO 02-2020 | LS-1204 AIR PURE SILVER). With the NF-1204 AIR Pure Silver, the analog device connection of the AIR family is now also available as a pure silver cable. Dimension, structure and arrangement of the conductors correspond to the respective copper versions. As with the LS-4004 AIR Pure Silver, LS-1204 AIR Pure Silver and LS-1204 Pure Silver, the signal conductors have been optimized. The AIR technology is a milestone in our 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.

AIR ISOLATION & FLEXIBILITY
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
ELECTROSTATICS AND CAPACITY
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.
HANDMADE IN GERMANY
Just like all speaker and audio cables from our Reference series, the NF-1204 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.
