Inakustik Reference Air LS-8005 Pure SIlver Spade Speaker Cable

Our Take

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.

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. 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.

Product Details

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 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.

• "Point-to-point Air Helix” for authentic sound
• Air as the ultimate dielectric minimizes capacitance
• Cross Link Super Speed waveguide for a balanced sound
• Pure silver conductors: one of the best conductors ever
• BFA banana & spade lug 360° adjustable
• Grounding option to divert interference

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 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.

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.
