Inakustik Reference LS-4005 Air Pure Silver
Inakustik Reference LS-4005 Air Pure Silver is an Ultra-high-end loudspeaker cable that will bring out the very best in audiophile reference systems.
AIR technology is a milestone in our more than 46-year company history and is causing a sensation in the hi-fi industry worldwide. The approach itself sounds relatively banal: The physically induced losses must be minimised in order to transmit the original music signal as authentically and neutrally as possible. And, thanks to the AIR technology, loss-free transmission is closer than ever before. It leads to a significantly better reproduction, which is not only subjectively audible, but also objectively measurable.
The insulation (or dielectric) of the AIR cables is practically perfect thanks to the air insulation, and hardly affects the sound at all. The structure, dimensions and arrangement of the conductors are optimised, and approach the limits of what is physically possible. Adding another highlight to this perfect audiophile foundation, we then focused on the conductor material of the cables. Copper in the appropriate purity is already a very good conductor. A superconductor, where electrical resistance is zero, would be perfect, of course.
Unfortunately, superconducting materials require temperatures of at least -70 degrees. Under realistic operating conditions, the best conducting material we have is currently silver. At 61.35 S/m (Siemens pro Meter), its conductivity is approximately six percent superior to that of copper. However, this precious metal is about 100 times more expensive.
Below you can learn more about the outstanding technical features of this cable, the innovations in the 5th generation and the physical principles used in the AIR technology.
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: Minimise 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.
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.
Pure silver conductors
Pure silver is regarded as the best conductor, delivering more detail across all frequency ranges. The charismatic sound of pure silver is primarily due to its high drift speed. Pure silver cables shouldn’t be confused with silver-plated cables. Silver-plated cables are said to lend a metallic and aggressive character to the sound, something pure silver cables never do.
The multicore structure
Inductance is critical to the capacitance of a loudspeaker cable, 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.
