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.

The Premium digital audio/video cable with a solid copper core conductor and double shielding is designed for connecting streaming devices, CD or Blu-ray players to an AV receiver or an audio DAC (digital-to-analog converter). It is also suitable for transmitting analog video signals. Wave impedance: Wave impedance is the most important parameter for cables that transmit high frequencies sand digital information. It results from the geometry of the cable and the dielectric constant of the dielectric used. The wave impedance is precisely adapted to the respective application in order to avoid reflections in the cable. This is the basic prerequisite for fast and error-free transmission of digital information and authentic reproduction. Gold-plated contacts: Surfaces are always rough when viewed under a microscope. The effective contact surface is thus reduced to the "peaks" on the respective surfaces. Gold is a very soft material that evens out tiny irregularities, increases the contact surface and reduces undesirable transition resistance. In addition, the precious metal gives the contact surfaces long-term protection from corrosion. Shielding: EMC interference, from sources such as mobile phone and WiFi networks, is constantly increasing. A dense (e.g. multi-layered) shielding is necessary to protect sensitive signals from this interference, so preserving the fine details.
The Star digital audio/video cable features a highly flexible design with dense spiral shielding and gold-plated connectors. It is designed for connecting streaming devices, CD or Blu-ray players to an AV receiver or an audio DAC (digital-to-analog converter). It is also suitable for transmitting analog video signals. A crucial factor for cables that transmit high-frequency digital information is the wave impedance. This value depends on the geometry of the cable and the dielectric constant of the dielectric used. Precise adjustment of the wave impedance to the respective application is essential in order to avoid reflections in the cable. This is the only way that digital information can be transmitted quickly and error-free, enabling authentic reproduction. Because surfaces always appear rough under the microscope, the gold plating of the connectors plays a decisive role. This roughness means that the effective contact area is reduced to the touching "peaks" of the surfaces. A very soft material, gold evens out these tiny irregularities, increases the contact surface and reduces undesirable transition resistance. In addition, the precious metal gives the contact surfaces long-term protection from corrosion. The cable adheres to the conventional coaxial design in which the "hot" signal conductor is located in the center and is protected by an enveloping shield that also serves as return conductor for the signal. This tried-and-tested design is suitable for a wide range of applications, and ensures that your audio and video transmissions are of the best-possible quality.
Interconnect Cables: Unlock Your System's True Potential
What are Interconnect cables and why do they matter?
