How is it possible that all along this path, which current flows from the power plant to the socket, the last one and a half meters of the power cord can make changes to the sound of the electronic device?
In fact, each device is located between two power lines: hot and neutral. From the perspective of the device, the power cable is not the last but the first one and a half meters. Its goodness (which translates into the sound qualities of an audio device) depends on the intensity of current it can deliver and how it deals with the effects of EMI's electromagnetic radiation of the component to which it is connected.
Most EMI radiation that affect sound quality in the system are produced by the audio components themselves. The basic source of audible sound degradation are power supplies in audio / video devices. This is because, in general, rectifier bridges are used in the power supplies, which generate a huge number of transient states when switching rectifier diodes. The design of the power cable can, however, significantly affect the reduction of these signals in the power supply. The power cord is actually part of the primary winding of the mains transformer. Most of the filters in power supplies are ineffective in blocking the components of very high frequency distortion, which is why many of them pass through DC current barriers. The sonic effects include high levels of background distortion, blurred or indistinct transients, and a general lack of transparency and clarity.
Our solutions reduce these problems in power cables dedicated to devices at any price level.
