SuperClamps are plug-in devices designed to improve the sound of your Hi-Fi or Home Cinema by reducing the effects of mains voltage spikes. They're designed by us and offer a very simple way to upgrade your system.

SuperClamps consist of two components – one a fast, solid state device culled from aerospace applications and the other a varistor to absorb the spike energy. These two components are mounted into a mains plug which you simply plug into a power socket (one close to your Hi-Fi system is ideal).

Nothing needs to be connected to the plug – they will work as long as the socket they are plugged into is switched on. They are not designed to replace the 13A plug on a cable.


A spike is a very brief over-voltage 'event' ranging from a few tens of volts above the highest legal peak voltage (360V for 230V), up to several thousand volts. They are typically under 1 millisecond in duration, are very common and often (though not always) the energy involved is small. Longer duration events are called surges and have the potential to do more damage, but mercifully these are less common.

Spikes are caused by things such as lightning strikes, power outages, tripped circuit breakers, fluorescent lights, refrigerators and washing machines switching on and off. The quality and severity of spike activity varies during the day, and from day to day. Even with well-designed equipment, spikes or transients – if regular – can and will prematurely stress and wear out critical mains-connected parts and their insulation.



In our opinion, high voltage spikes can also cause audible degradation of Hi-Fi sound by their effect on a Hi-Fi system's power supply and by raising the background noise level in amplification circuits. The spikes saturate the core of the mains transformer, preventing normal transformer operation during the period of each spike and causing distortion to the waveform. Mains spikes reduce the capacity of the power supply by 'strangling' the transformer operation producing subjective effects on an amplifier like softened bass and increased high frequency distortion.





You can fit as many SuperClamps as you like. One customer kept adding them until he stopped hearing improvements - and he had over 15. The SuperClamps work particularly well plugged into unused sockets throughout the house and if you need to buy more of the SuperClamp Plugs featured on this page there's a saving to be had if ordering a triple pack - see the triple pack here




SuperClamps are available mounted into a mains plug as on this page. They are also available mounted in a two-way 'cube' – the SuperCube – which is useful if you don't have a spare socket to connect a SuperClamp plug.

SuperClamps are also an optional upgrade on our PowerBar mains extensions and any power cable that is fitted with a WattGate plug. The components are fitted internally for optimum performance. To add a SuperClamp to any of these products, check the 'SuperClamp' box on the product page at the point of ordering and it will be included.

SuperClamps are also incorporated as standard in the Silencer and MiniPurifier power filters, and also into our XBlock mains extensions. If you have any of these products, you'll be benefitting from the SuperClamp.


SuperClamp components work a bit like a crumple zone on a car - they partly absorb energy by micro-degradation. Whereas modern car crumple zones normally collapse on a single impact, SuperClamp components are designed to deminish over a long period of time; this is why we recommend replacement approx every 5 years to maintain your SuperClamp's performance.
