    Here`s why

AIR cables for unadulterated sound

Our Air technology is the product of our profound in-house know-how and years of research work. It defines new standards. The sensitive sound signals are influenced by a wide variety of parameters: resistance, inductance, capacitance, insulation and skin effects all change the sound. The fragile signals are distorted during transmission. Our specially developed AIR technology minimizes any resulting losses. Now already in its 5th generation.

  • Press review | Image-hifi - Heinz Gelking | LS-2404 AIR

    "The LS-2404 Air creates a little more space in the otherwise generous sound of my chain. The stage appears wider and deeper, the background darker, the action more relief-like. It's amazing how much energy and excitement has made it from the concert via the sound carrier into my listening room. Clapping, cheering, whistling in the audience."

  • Press reviews | Fidelity - Michael Vrzal | LS-4004 AIR

    "The lowest bass frequencies seemed to stand in the room with a previously unknown sovereignty.  And that with harmonic details, three-dimensionality, sound separation and dynamics at their very best. “This cable has what it takes to lift the performance of my chain into the next higher class! That's how big the difference was between the entry-level cable, which is not bad per se, and the ultimate cable from the Black Forest"

High-end audio cable Quality: Referenz AIR Helix Point-to-Point
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

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

Where does fine sound begin? Where does it end? These questions ring constantly in our ears. The truth is, various factors have a major impact on the sound quality produced by audio systems, and one of these factors is power supply. It is subject to fluctuations that vary depending on the location of your home (in a city or a rural environment). If we look at things from a purely physics perspective, the music produced by a loudspeaker is ultimately nothing more than domestic current converted into sound. This statement sounds almost too banal compared to the hi-fi jargon we are all accustomed to. Unfortunately, all too often we ignore where the sound actually comes from and the importance of having a stable power supply. A “clean” current is the raw material of fine sound, and our AC-4500 Power Station makes sure that this is what you get. The AC-4500 Power Station is available in several versions – from a basic model with one filter for all six sockets through to the top model that comes equipped with six separate filters, one for each socket. The models differ not only in the number of filters they are equipped with, but also in the combination of filter types they provide – type I (for analog devices) and type II (for digital devices). The AC-4500 Power Station was developed completely in-house, and each unit is manufactured in the company’s own facility. Units subsequently undergoes rigorous testing with documentation of the results. Because safety is paramount for this type of unit, we have also arranged for an accredited laboratory to verify CE/CB conformity. The Power Station’s sensitive technology is protected by a robust metal housing made of 2 mm-thick galvanized sheet steel. It has an elegant front panel made of brushed aluminum. The interior of the housing is designed so that the socket groups are shielded from one another, and any interference stemming from the connected devices is unable to propagate.

A hi-fi system basically reproduces nothing other than modulated household electricity. This means this should arrive at the device as constantly as possible. Here the mains cable (power cable) plays a significant role. The big challenge for power supply cables is extreme current peaks. They are caused by the connected devices themselves converting alternating current into direct current. These extreme current peaks cause a whole range of undesirable effects. Specially designed for connecting up top-notch high-end audio systems, the Referenz AC-2405 AIR mains cable is based on the already legendary AIR technology. In conjunction with this technology, i.e. the "omission" of insulation material, which would "soak up" part of the energy like a sponge, the Referenz AC-2405 AIR is able to transport very large amounts of energy in a very short time. Many design details of the Referenz AC-2405 AIR counteract the undesirable effects and make it an outstanding energy pipeline for the highest audiophile requirements. However much we focus on high-end sound, safety plays a particularly important role in this cable category. For this reason, every Referenz AC-2405 AIR cable is tested extremely carefully. In addition to an exhaustive functional test, each cable is also subjected to an insulation and high-voltage test. The results are documented, and each cable is given an individual serial number.
