"HiFi and power supply – safety first!"
In this video, we give you an insight into the product development of our power cables. The power supply is the foundation of any hi-fi system. In addition to improving sound quality, safety aspects play a special role in hi-fi power cables. Extensive testing processes are required to ensure that a power cable meets CE conformity. That's why every one of our hand-made Referenz AIR power cables is put through its paces with the utmost care. After an intensive mechanical and electrical function test, every hi-fi mains cable is subjected to an insulation and high-voltage test. The result is logged and assigned to the respective mains cable by means of an individual serial number.
