REFERENZ LS-4005 AIR Pure Silver (2x3.0m) BFA

REFERENZ - Speaker cable

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 minimized 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 optimized, 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.
