Product information "USB-2405 AIR Pure Silver | A < > B"
The Air Helix construction of the Referenz USB-2405 AIR is truly unique. To achieve an almost perfect air isolation, we developed a special clip system. Inside the cable, a large number of these clips form a supporting structure that keeps the signal conductors suspended freely in air in a helical arrangement and guides them through the high-density shielding at a precisely defined distance. The flexibility of this construction is achieved through two support rails that not only hold the clips together but also maintain the exact spacing between them.
Strictly speaking, the term “digital” only exists in mathematics in the form of the binary number system. In the technical world, there are no purely digital signals. To detect zeros and ones, defined voltage thresholds and timing windows are used. The transition from a zero to a one, or vice versa, always requires a certain amount of time during which the signal level passes through all intermediate values, for example from 0 volts to 5 volts. Capacitive loads, dielectric losses, noise, and electromagnetic interference caused by cables can further influence this transition. This results in timing deviations known as the jitter effect, making precise reconstruction of the audio signal more difficult or even nearly impossible.
To get closer to the pinnacle of audiophile perfection, we also carefully examined the conductor material. Copper with the right purity is already an excellent conductor, but a superconductor with no ohmic resistance would be the ideal solution. However, superconducting properties require extremely low temperatures of at least -70°C. Under realistic conditions, silver is currently the most conductive material available. With a conductivity of 61.35 S/m (siemens per meter), it outperforms copper by around six percent.
Many manufacturers use silver-plated conductors, which over time can result in a sound character often described as "bright," "metallic," or even "harsh." We use pure silver conductors instead, which provide a much more neutral sonic character. Due to the higher electron mobility, our pure silver cable delivers a more detailed and powerful sound performance across the entire frequency range. Silver, of course, is also around one hundred times more expensive than copper.
USB connectors are known to only fit in one direction. This can be inconvenient, as the position of USB ports varies between devices. To adjust the cable routing, the cable often needs to be twisted significantly, placing stress on the cable, connectors, and sockets while also affecting the overall appearance of the installation. Our newly developed USB connectors with a 180° rotation mechanism provide the solution. Each connector can be rotated by ±45°, meaning that a total rotation of ±90° from one connector to the other is possible. This is the final refinement for a perfectly installed cable connection.
The dense shielding of the Referenz USB-2405 AIR protects the sensitive signal from electromagnetic interference. Beneath the shielding is the innovative Air Helix construction, where air and the precisely defined spacing between the conductors act as the dielectric, preventing dielectric losses and significantly reducing capacitive loading. Together, these design elements make it easier for the digital-to-analog converter (DAC) to process the signal and help optimize the reconstruction of the audio signal.

The jump from a zero to a one or vice versa always requires a certain time, during which the signal level passes through all intermediate values, from 0 volts to 5 volts, for example. Capacitive loads, dielectric losses, noise and electromagnetic interferences caused by cables additionally manipulate this change. This results in temporal shifts, or the, “jitter effect”, which makes precise reconstruction of the audio signal difficult or almost impossible.
New 180° USB connector: As we know, USB connectors can only be inserted in one direction. This can be difficult, as the position of the USB sockets in devices varies. To adjust the course of the cable, it often has to be twisted quite a lot, which puts strain on cables, connectors and sockets and also looks unsightly. Our recently developed USB connectors with 180° rotation mechanism offer a solution: Each one can be rotated by +/- 45 degrees, enabling a total rotation of +/- 90 degrees from connector to connector, thus providing the finishing touch for perfect cabling.
The dense shielding of the Referenz USB-2405 AIR cable protects the sensitive signal from electromagnetic interferences. Under the shielding is the innovative air helix structure, where air and the spacing between the conductors act as insulators, preventing dielectric losses and significantly reducing capacitive loads. On the whole this makes the digital-to-analog converter’s (DAC) work easier and perfects the audio signal’s reconstruction.

The Air Helix architecture of the Referenz Digital-2405 AIR is absolutely unique. We have developed a special clip that enables us to come as close as possible to perfect air insulation. Inside the cable, a large number of these clips form the supporting structure that keeps the helically-arranged conductors apart in the air and guides them through the shielding at a defined distance from each other. Cable flexibility is assured by means of two struts that ensure the clips remain together but also at a precise distance from one another. With coaxial cables, the shielding is generally also used as a ground wire. The Referenz Digital 2405, on the other hand, has a double-symmetric design with two positive and two negative conductors. This means that the shielding is completely separate and the signal remains free of interference. Even if it sounds paradoxical, thanks to the innovative air insulation in this cable, hi-fi becomes a simply breathtaking sound experience. Click here and discover the exciting details
With the Digital-2405 AIR Pure Silver, the digital member of the AIR family is now also available as a pure silver cable. The dimensions, structure and arrangement of the conductors correspond to the respective copper versions. As with the LS-4005 AIR Pure Silver, LS-2405 AIR Pure Silver and LS-1205 Pure Silver, the signal conductors have been optimized. AIR technology is a milestone in our more than 40-year company history and is causing a sensation in the hi-fi industry worldwide. The approach itself sounds relatively banal: The physically induced losses must be minimized in order to transmit the original music signal as authentically and neutrally as possible. And, thanks to the AIR technology, loss-free transmission is closer than ever before. 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 practically perfect thanks to the air insulation, and hardly affects the sound at all. The structure, dimensions and arrangement of the conductors are optimized, and approach the limits of what is physically possible. Adding another highlight to this perfect audiophile foundation, we then focused on the conductor material of the cables. Copper in the appropriate purity is already a very good conductor. A superconductor, where electrical resistance is zero, would be perfect, of course. Unfortunately, superconducting materials require temperatures of at least -70 degrees. Under realistic operating conditions, the best conducting material we have is currently silver. At 61.35 S/m (Siemens pro Meter), its conductivity is approximately six percent superior to that of copper. However, this precious metal is about 100 times more expensive.
