As bonkers as the price-tag may seem, this cable brings the biggest improvement of any of the mains products iwe've tested.

This particular version of the company's Reference PowerKord sports an optional Wattgate plug – and the results are remarkable.

Levels of detail, dynamics and clarity of sound are improved upon tenfold. Gains in picture quality aren't quite as substantial, but the cable still gives images a serious boost in resolution and cleanliness.

Not everyone can afford to spend over £200 on a mains cable, but those who own high-end components costing £2000 upwards should seriously consider this PowerKord lead.
