Beautiful noise

AUDIOPHILES know that the electricity supply drawn from their main community power grid is "dirty", containing all sorts of interference that can distort the music signal and reduce the sonic performance of their equipment.

These radio frequency artifacts are introduced by the thousands of household appliances like

TVs, PCs and microwaves that draw their power from the grid - which explains why music playback sounds so much better late at night when most of these items are switched off.
