Inakustik - Referenz NF-4005 AIR Stereo RCA <> RCA - Interconnect Cable Pure Silver

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 Pure Silver 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.

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.

New RCA SL connectors (SolderLess): Soldering is a proven and established connection technology, but it is not without its weaknesses. These include the solder used in the signal path, which reduces the conductivity, and the generation of thermal voltages, even if it is kept to a minimum. With our recently developed SL (SolderLess) RCA connector, the connections from the signal conductor to the contact element are pressed with the highest precision and with a pressure of 1.5 tonnes. A further seemingly tiny improvement that brings great rewards in terms of audio performance.
