Cable capacitance plays a decisive role, especially for audio cable connections between individual devices. As the signal sources are very weak and react sensitively to high cable capacitance, audio cables are virtually predestined for air insulation using air helix technology. In addition to this, we have also developed a completely new and entirely solder-free RCA connector for the Referenz NF-1205 Air. It consists of several component parts that are only joined together during the course of the assembly process. As with the loudspeaker cable, the thin layer of enamel is first removed from the high-purity copper wires of the "Cross Link Super Speed" waveguide by machine. Then, the contact pin of the connector, which is made of tellurium copper, is pressure-grouted with the conductor using a force of 1.5 tonnes. The connection of the shielding is also completely new: It is now hermetically sealed with screws. Click here and discover the exciting details

New XLR 180° plug: It is only possible to insert XLR connectors in one direction. This can be annoying as the position of the XLR sockets in devices varies. In order for the cable to fit, it must sometimes be twisted by force. This puts a strain on cables, plugs and device sockets and sometimes simply looks a mess. The newly developed XLR 180° plugs can each be rotated by +/- 45 degrees, i.e. +/- 90 degrees in total. The finishing touch for perfect cabling. Click here and discover the exciting details
Breathtaking sound thanks to air insulation - we have already created many innovative designs on the way to perfect insulation, such as DUO-PE insulation or PETS (PE Tube Support). The Referenz NF-2405 cable is another true milestone and an absolute world first in the cable sector. Normally, the conductors are kept at a distance from each other by more or less high-quality filling and insulation materials. With the NF-2405, however, the conductors run through a series of clips connected in series, which form the inner framework and give the NF-2405 exceptional flexibility for high-end cables. The NF-2405 is manufactured entirely in Germany, like all speaker and audio cables in the Referenz series. The clips are assembled by hand with meticulous care in the company's own factory and then the Cross Link super-speed waveguide is threaded in. After this, the resulting air helix is also shielded by hand and given a PE network jacket before the finished cable is assembled using the RCA plugs we developed ourselves. New RCA SL connector: Soldering is a reliable and well-established joining technique, but it has its drawbacks. Disadvantages include the presence of poorly conducting solder in the signal path and the emergence of low thermoelectric emfs. With the SL RCA Plug developed in-house, the connections from the signal conductor to the contact elements are precisely pressure-grouted together using a force of 1.5 tonnes. A further seemingly tiny improvement that brings great rewards in terms of audio performance. Click here and discover the exciting details

Good sound needs space! In developing our Air technology, we have proven that an audio cable’s insulation plays a decisive role and has a significant influence on the sound. This is due to dielectric losses and the electrostatic properties of the insulating materials, which burden the hi-fi system like heavy luggage and make it sluggish. By “omitting” this strain we then help the entire hi-fi chain to achieve top performance. We do this with special clips that guide the signal conductors through the cable in a row and freely suspended. A cable’s geometry also influences these factors. Bigger distances mean less load. This is exactly where our NF-4005 AIR comes in: The AIR helix design and the cable’s dimensions create even more space and air between the signal conductors. The cable thus forms a wide audiophile corridor and rolls out the red carpet, so to speak, for every sound detail. New RCA SL connectors (SolderLess): Soldering is a proven and established connection technology, but it is not without its weaknesses. These include the solder used in the signal path, which reduces the conductivity, and the generation of thermal voltages, even if it is kept to a minimum. With our recently developed SL (SolderLess) RCA connector, the connections from the signal conductor to the contact element are pressed with the highest precision and with a pressure of 1.5 tonnes. A further seemingly tiny improvement that brings great rewards in terms of audio performance. Click here and discover the exciting details

Because the outputs on hi-fi devices only supply extremely weak signals and are sensitive to high cable capacitance, the capacitance of a cable plays a significant role when connecting components together. A “low-pass filter” can be created that cuts off high frequencies and also causes phase shifts. This is the reason why RCA and XLR audio cables are ideal companions for the air-based insulation used in the MICRO AIR technology. Another special feature of the NF-204 Micro AIR is its symmetrical architecture, which guarantees high immunity to EMC radiation. Alone or in combination with the LS-204/LS-204-XL, the NF-204 Micro AIR opens up the connection floodgates and allows your components to perform at their very best.

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

Precisely because audio signals are so sensitive, we have equipped our Referenz NF-202 phono cable with some extremely effective technologies: Optimum DUO-PE II insulation, air-filled PE tubes, an innovative GAP connector and, above all, extremely fine, solid conductors made of high-purity OFC copper guarantee uniform runtimes and crystal-clear signal transmission. The ground and signal conductors are the same size and arranged symmetrically. The PE network jacket prevents micro-vibrations.
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
