Referenz AIR Pure Silver Cables

The good old record sounds more vibrant than ever. The demand is astonishing, even for experts. The figures for records sold are increasing just as surprisingly as the number of record players. It’s a real boom. But how to improve the sound? One way is to use a new, better cable between the tonearm and the phono amplifier. The Phono-2405 AIR is a cable created to deliver top sound. What sets it apart is an absolutely unique air insulation, called the Air Helix. We have developed a special clip for this technology. It separates the two cable bundles, keeps them apart, and virtually embeds them in air. Using a large number of these clips, it is possible to route earth and signal extremely stably over longer distances. Why the effort? With this approach it is possible to pass on the sensitive signals without slowing them down - the result is fast and high-resolution sound. The Super Speed waveguides are threaded by hand and the clips are fitted with great care in the company's own factory. After this, the resulting Air Helix is also shielded and fitted with the PE network jacket by hand. Finally, the rhodium-plated connectors are fitted and cable functionality is tested. Because it's all about the most important, smallest signals: There is nowhere in the audio world where smaller currents flow that need to be passed on perfectly. The signal level of an MM or MC system is extremely sensitive, at just a few thousandths of a volt. In addition to this, the systems have an inductive character. In combination with the cable capacitance, they form what is known as an oscillating circuit, which favors specific frequencies. If these frequencies are unfavorable due to excessively high capacitance, this has a major effect on the harmony of the sound. Extremely low capacitance and dielectric losses are just two advantages of the Referenz Phono -2405 AIR. They form the basis for unadulterated enjoyment of your vinyl jewels. The sound of good records can hardly be resolved in a finer way than this. 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 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.

Experts have already been impressed by the LS-1204 AIR (copper). This is how AUDIO summed it up: "A stroke of genius that shows competitors how it should be done – in terms of sound, too. This was wonderfully dynamic, with the most fabulous drive reaching the speaker cones. Admittedly, the price is not low, but the acoustic yield is truly world class. What's more, everything was made by hand. You can feel the love for the product." With the LS-1205 AIR Pure Silver, the currently most filigree model in AIR technology is now also available as a pure silver cable. The structure, dimensions and conductor arrangement of this cable correspond to the copper version of the LS-1205 AIR. As with the LS-4005 AIR Pure Silver and LS-2405 AIR Pure Silver, the conductors have been optimized. Pure silver is used as the conductor material for the LS-1205 AIR Pure Silver too. Under realistic conditions, silver is currently the most conductive material. At 61.35 S/m (Siemens pro Meter), its conductivity is approximately six percent superior to that of copper. The electrons move 1.5 times faster than in a copper conductor! Click here and discover the exciting details
