The inconsistency of the UK mains supply is almost legendary: at 7.45pm most weekdays 20 million kettles are boiled, and the strain on the national grid is immense with voltage stability suffering as a consequence. This is why your hi-fi system invariably sounds better very late at night, because demand is at its least. Our mains products will help you battle the vagaries of the country’s mains supply and get the best from your hi-fi or AV system. Mains products DO make a difference – especially ours!
