CAT-2405 AIR
The CAT-2405 AIR is a high-end LAN cable designed for connecting audio components in streaming setups. It is based on our specially developed Air Helix construction, which enables low-loss and interference-resistant signal transmission. For this construction, we have designed a special clip that forms a stable supporting framework inside the cable. Several of these clips hold the signal pairs in a helical shape and at a defined distance freely in the air. The entire arrangement runs within a high-density shield. Two connecting bridges keep the clips evenly spaced and at the same time provide the necessary flexibility in the cable structure. Digital signal transmission: In mathematics, digital information is represented as binary values, but technically it is transmitted via analog voltage curves. To distinguish between states such as "0" and "1", voltage thresholds and time windows are defined. The transition between these states does not occur abruptly, but continuously—the signal passes through intermediate values, for example, between 0 and 5 volts. Capacitive loads, dielectric losses, noise, and external electromagnetic influences can distort these transitions. This results in timing shifts in the signal, known as jitter. Jitter makes it harder to assign data precisely in time and impairs the reconstruction of digital audio signals. Advantages of the Air Helix construction: The overall shielding made of dense braid, as well as additional foil shields for each pair of wires, effectively protect against external interference. The Air Helix construction uses air as a dielectric and ensures a constant distance between the wire pairs. This arrangement reduces crosstalk and capacitive losses, contributing to unadulterated signal transmission. Streaming components and integrated digital-to-analog converters (DACs) benefit from the improved signal quality and can process data more precisely. CAT connector with rotation mechanism: Conventional RJ45 connectors can only be plugged in at a fixed orientation. Depending on the position of the socket, this can result in unfavorable cable routing and mechanical stress on the connector, cable, and socket. To counteract this, we use rotatable RJ45 connectors with a 180° mechanism. Each connector can be rotated by about ±45°, resulting in a total adjustability of about ±90° between both connectors. This allows the cable to be routed without tension and in a space-saving manner.

CAT 8.1
Strictly speaking, "digital" exists only in mathematics as a binary number system. In technical reality, there are no purely digital signals. To identify zeros and ones, electrical voltage thresholds and time windows are defined. When switching from zero to one or vice versa, the signal passes through all intermediate values — for example, from 0 volts to 5 volts. Capacitive loads, dielectric losses, noise, and electromagnetic interference caused by the cable additionally affect this transition. This results in timing deviations, known as jitter, which complicates the precise reconstruction of the audio signal. The Reference CAT 8.1 cable is a LAN cable specifically designed for connecting high-end components in a home network. An additional shielding mesh, the so-called hyper-shield, protects the sensitive signals from electromagnetic interference. Furthermore, each data pair is individually shielded with an additional foil layer. This combination effectively reduces interference and supports streaming players and built-in digital-to-analog converters (DACs) in reproducing the audio signal with minimal loss and maximum precision. This ensures that the Reference CAT 8.1 cable provides a stable and high-performance connection - ideal for demanding audio and video streams in a home network.

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.
