Product information "LS-8005 AIR"

High-end loudspeakers need power – and a lot of it, quickly and precisely. For the perfect sound the power must correspond one hundred percent with the analog image of the original sound source, be it an A cappella soloist or a stomping rock concert. A few technical tricks that help to skillfully circumvent physical influences are required to deliver this power to the loudspeaker right on time and holistically. Line resistance and line inductance play an important role with speaker cables.

The powerful Referenz LS-8005 AIR has impressive 32 Cross Link Super Speed waveguides with an enormous total cross-section of 38 mm². The cross-section alone, however, does not make a good cable. The smart nesting of the conductors almost completely eliminates magnetic fields, paving the way for the finest sound facets and powerful pressure in equal measure.

Good sound needs air! In developing our Air technology, we have proven that an audio cable’s insulation plays a key 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.

Grounding option: The number of cell phones, WiFi routers, Bluetooth devices, PV systems and charging stations etc., is constantly increasing. This also increases the potential for electromagnetic interferences, which can affect hi-fi and high-end systems. Cables act like antennae and can transfer the interferences to the devices, where they overlay the audio signal in sensitive circuit areas, resulting in a “washed out” sound. Effective shielding and grounding concepts are crucial to protect the sound. The grounding cable of a record player is a very well-known example of this. The LS- 8005 AIR is equipped with a grounding option, which, depending on the configuration, can be connected to the amplifier’s earth, the protective conductor or earth or a grounding box, to divert disturbances.

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.

  • "It's not magic, it's a great cable. The best cables are not those that get the most out of a hi-fi chain, they're the ones that lose the least of the original sound. Cables should behave inconspicuously with regard to sound."

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


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 multicore structure

Inductivity is a critical parameter in loudspeaker cables. By cleverly arranging the conductors in the multiply nested multicore structures, overlapping magnetic field areas are created that significantly reduce inductance. This allows the entire frequency spectrum, including high frequencies and dynamic impulse sequences, to be transported in an unimpeded way and with no delays. The music seems more exquisitely detailed, and the sound gains in fine dynamism. All details are kept distinct yet harmonious at the same time.

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.


Grounding option

The growing number of cell phones, WiFi routers, PV systems and charging stations increases potential electromagnetic interference, affecting hi-fi systems. Cables can act as antennae, transferring interference to devices and degrading sound quality. Effective shielding and grounding are essential for protection. The LS-8005 AIR includes a grounding option that can connect to an amplifier’s earth, protective conductor, or a grounding box to divert disturbances, similar to a record player's grounding cable.

BFA Banana & Spade 360°

Movement across three axes make the 360-degree BFA and spade connectors really easy to connect and disconnect. Difficult set-up operations that put a strain on both cables and devices are a thing of the past. The connectors can easily be attached to terminals from a wide range of manufacturers. No awkward bending is necessary, avoiding damage to surfaces and potential contact resistance. Set-up is fast and problem-free. The attractively designed connectors are the perfect complement to the outstanding sound.

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.

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. To get closer to the pinnacle of audiophile perfection, we also carefully examined the conductor material. Copper in the right purity is itself already an excellent conductor, but a superconductor with no ohmic resistance to the current would be simply perfect. The material’s superconducting properties, however, require extremely low temperatures of at least -70 degrees. Under realistic conditions, silver is currently the most conductive material. With a conductivity of 61.35 S/m (siemens per meter), it outperforms copper by around six percent. Many manufacturers only use silver-plated conductors, which over time can seem, “bright”, “metallic” and even, “annoying”. We, on the other hand, use pure silver, which has a far more neutral sound. Due to the higher drift speed of the electrons, our pure silver cable delivers a more penetrating and sumptuous sound performance, across all frequency ranges. On the other hand of course, silver is about one hundred times more expensive than copper. Grounding option: The number of cell phones, WiFi routers, Bluetooth devices, PV systems and charging stations etc., is constantly increasing. This also increases the potential for electromagnetic interferences, which can affect hi-fi and high-end systems. Cables act like antennae and can transfer the interferences to the devices, where they overlay the audio signal in sensitive circuit areas, resulting in a “washed out” sound. Effective shielding and grounding concepts are crucial to protect the sound. The grounding cable of a record player is a very well-known example of this.

NF-4005 AIR | XLR
High-end audio cable Quality: Referenz AIR Helix Point-to-Point
Length: 1 m
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 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 new XLR 180° plugs developed in-house can be rotated by +/- 45 degrees, i.e., up to a total of +/- 90 degrees from connector to connector. The finishing touch for perfect cabling.

AC-4500 | SCHUKO
High-end power filters Quality: Referenz 2 filter types | DC suppression
Filter configuration: 3 x analog - 3 x digital | Model: Black
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.

AC-4005 AIR | Schuko - C19 | UHQ
High-end mains power cable Quality: Referenz AIR Helix Point-to-Point | Multicore
Length: 1 m | Connector: SCHUKO> C19
Dynamic music places an impulsive load on the output stages of an audiophile hi-fi chain. That's why we developed the Referenz AC-4005 AIR mains cable. Specially developed clips are used to keep the individual wires at a defined distance apart. The resulting "air dielectric" reduces power losses to a minimum and significantly improves the electrical parameters. The multicore structure leads to an overlap, so compensating for the magnetic fields around the individual cores. The line inductance is greatly minimized, depending on the number of cores, and the skin effect caused by steep current flanks at high frequencies is clearly and audibly reduced. In addition, the usable conductor cross-section is effectively extended, and without the negative effects of thicker cables. A dense shielding braid of tinned copper protects neighboring cables and components against external interference and also prevents oxidation. Each of our Referenz AIR mains cables is tested and inspected with the utmost care. The results are documented, and each cable is given an individual serial number.
