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 and Digital 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 Phono 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 rhodium coated plugs.
