Problems of the power grid
In the urban power grid, there are significant low and high frequency electrical interfering fields flowing from the power lines into the devices and then distributing to all Hi-Fi devices of the audio system via the cable connections.
In addition, directly within the domestic power grid there are critical electrical consumers (switching power supplies, computers, energy-saving lamps, refrigerators, heating systems, cooktops, routers, AV systems, etc.), which feed massive low and high-frequency interfering fields into the power grid distributing to all Hi-Fi devices via the cables.
