Fit our best spike clamps

MegaClamps 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 an easy and effective way to upgrade your system.

MegaClamps use components culled from the communications industry which are more effective at absorbing mains spike activity than anything we have tested before. The MegaClamp component is mounted in a 'wall-wart' type plug which simply needs to be plugged into a power socket close to your Hi-Fi system. A spare socket in your mains extension is ideal.

The versions

MegaClamps are available mounted in a compact wall-wart as shown on this page. They are also available mounted in a two-way 'cube' - the MegaCube - which is useful if you don't have a spare socket to connect a MegaClamp.

The MegaClamp is also an optional upgrade on our MiniPurifier mains conditioner, saving you money and space.

The MegaClamp is fitted as standard to all new PowerBlocks mains extensions.

It doesn't need to be replaced

Unlike the SuperClamp which wears out and becomes less effective over time, the MegaClamp is many times more effective than the SuperClamp and has the advantage of not needing to be replaced every five years. As with all of our clamping products, we recommend that you unplug your Hi-Fi or Home Cinema equipment in the event of a storm - nothing will protect your equipment in the event of a direct lightning strike.

  • What are spikes?

    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.

    Review
    You can read many opinions (controversial) on the net regarding this product and its usefulness. Russ Andrews offers 60 days money back so I decided to try one. I have used the Silencer previously and could hear the benefits it provided. So I decided to try the megaclamp/silencer combo. My system is connected to a top grade extension block. After plugging the new product I noticed a greater bass definition, more open mid and high range on a quieter background. The difference is subtle but nevertheless there. I had a friend who came to hear it and could confirm what I experienced. To me the subtle (but noticeable change) is worth having so I will keep the unit. Try it for yourself and if you don't hear/like the difference it makes, you can send it back!.
