Breathtaking sound through air insulation - On their way to perfect insulation, German cable manufacturer in-akustik has realized many innovative designs—for example, the DUO PE insulation or the PETS (PE tube support). Now, another groundbreaking invention has arrived: the Referenz NF-2404. A product that again raises the bar and approximates the ideal of pure air insulation as closely as never before. When it comes to high-end applications, air is still the best insulator currently available as it achieves low capacities and low losses. With NF cables (fitted with RCA or XLR plugs), these factors are critical for creating an exceptional connection. But consistent design is equally important: The precisely defined distance between the conductors and the shield must be maintained at all times. Flexibility is another key challenge - the cable must allow for conveniently running it behind your hi-fi equipment or rack. Just like all loudspeaker and audio cables from the Referenz series, the NF- 2404 is entirely made in Germany. The clips are meticulously assembled by hand at the on-site factory and then threaded into the Super Speed waveguide. The resulting Air Helix is then provided with a shield and the PE network jacket and finally fitted with GAP-RCA-II or XLR plugs. It may seem paradoxical but thanks to this highly innovative air-insulation design, enjoying hi-fi sound becomes a virtually breathtaking experience.
Air Helix structure
• Extremely low capacities thanks to air dielectric
• Super Speed waveguide
• Low longitudinal inductance resulting from braided lacquered conductors
• PE network jacket preventing micro-vibrations
• Braided shield made of low-oxidation copper
