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.

Thanks to the Air Helix design, the conductors run freely suspended through the length of the cable.
The Air Helix architecture permits signal conductors to be insulated to practically 100% by air. Special clips were developed to provide the supporting framework. Positioned at defined intervals inside the cables, these clips keep the helically-arranged conductors apart. Cable flexibility is assured by means of two struts that ensure the clips remain together but also at a precise distance from each other. This architecture is unique, bringing low capacitance and minimum dielectric losses – a true milestone in the search for open and unadulterated sound.
Our physical approach: Minimize losses for true-to-original playback.
Our Referenz AIR cables transport audio signals between source, amplifier and speaker in an authentic way and with a minimum of loss. You can enjoy music that precisely expresses the emotions of the artists at the time of recording – sensual, subtle, light-hearted or orchestral right through to full-blooded and rocking. Vocals and instruments are delivered in unadulterated form. Everything remains vibrant and full of emotive energy. Favorite tracks and pieces continue to trigger strong feelings even when you’ve heard them a hundred time over.
To the point
AIR Helix
The Air Helix architecture enables the signal conductors to run freely suspended through the length of the cable and permits signal conductors to be insulated to practically 100% by air.
The dielectric
The dielectric Using air as a dielectric lowers capacitance to a minimum. In comparison with other insulators, using air as a dielectric leads to no increase in capacitance and creates no dielectric losses.
Multicore structure
By cleverly arranging the conductors in the multiply nested multicore structures, overlapping magnetic field areas are created that significantly reduce inductance.
The conductors
The Cross Link Super Speed waveguide avoids so-called skin effects and delivers a balanced sound, even with complex music passages and high volume levels.
Pressure-grouted contacts
The connectors are pressed directly into the conductor material of the cable using a special tool with a force of 1.5 tonnes. Contact resistance and other negative solder effects are avoided.
Point-to-point Air Helix for end-to-end connections
A new feature in the 5th generation of in-akustik’s Air Helix architecture is the point-to-point connection. Specially designed transitions are available for each type of cable and connector. Across the complete length of the cable – point-to-point AIR Helix. It may sound trivial at first, but the results are impressive. Sound signals are transported with minimized losses, right through to the final centimeters. The sound is more detailed and dynamic than even before.
The conductor structure
The Cross Link Super Speed waveguide avoids skin effects caused by eddy currents in the conductor. Thanks to the braided structure, the waveguide is able to precisely transport even extreme current peaks. A lacquer coating around each wire prevents eddy currents within the conductor and protects against oxidation. All this results in a conductor that delivers a balanced sound consisting of vibrant and never overemphasized timbres, even in complex musical passages and at high volume levels.
The conductor material
The conductor material is a crucial factor for the transmission of sound signals. Any contamination worsens the conductance and increases the background noise. We only use pure, oxygen-free copper in our AIR cables. We ensure that only carefully selected batches of pure copper are processed. We take great pains to measure the quality of the copper before it is sent to the mill for drawing to the required cross-section over the course of a multi-stage process.
The shielding
EMC interference, from sources such as mobile phone and WiFi networks, is constantly increasing. This interference impairs the sensitive audio signal. Interference occurs when signals of different frequencies overlap. This can result in unwanted distortions that have nothing to do with the original signal. Dense shielding is therefore essential to protect the extremely sensitive music signals from this interference so that even the finest details are preserved.
Cable manufacturing unit
The beating heart of in-akustik is our manufactory. This is where our success story is rooted – permeated by a congenial working atmosphere, a love of music and a passion for detail. At in-akustik, we believe musical enjoyment stems from a listening experience that remains as close as possible to the original recording and the artist’s interpretation of the piece. That’s why we boast a committed workforce that combines curiosity with a keen sense of precision. With a fascination for music and things that are really special – like the development of our complex AIR cables.
Handmade
Each cable is handcrafted with the utmost care. Our extensive know-how and the qualifications of our team enable us to manufacture the complex cables in a customized manner. Apart from the finest of materials, our most important resource is the manual dexterity of our cable assemblers. In assembling our outstanding cables, they demonstrate meticulousness, composure and dedication.
Rigorous quality control
We manufacture in accordance with the highest standards. Rigorous quality control is carried out before, during and subsequent to assembly. We verify the tolerances of ever individual component. At every stage of manufacturing, we check the configuration and electrics for short-circuits. We also conduct functional and mechanical testing. No product leaves our manufacturing unit without a final quality check.
Sensitive phono signals
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 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.
RCA SL connectors (SolderLess)
Soldering is a reliable and well-established joining technique, but it has its drawbacks. Disadvantages include the presence of less conductive solder in the signal path and the emergence of low thermoelectric efms. The RCA SL connector of our fifth generation Referenz AIR cable is now also pressure-grouted from signal conductor to contact elements with 1.5 tons, like all other Referenz AIR cables. A further seemingly tiny improvement that brings great rewards in audio performance.
Rhodium-coated
The best cable requires optimum connection technology. We use tellurium copper, a harder metal alloy that maintains the high conductivity value. Much superior to that of brass connectors. The rhodium coating ensures long-lasting contact and corrosion resistance. The stable conductivity is even maintained with frequent conversions. This is better than gold contacts, which wear out quicker.
Pressed contacts (1.5 tonnes)
The contact elements of the connectors are pressed directly into the conductor material using a special tool with a force of 1.5 tonnes. This creates a stable and reliable connection without the use of solder or ferrules. Transition resistances and negative effects are avoided to ensure optimum signal transmission.
