Evolution-300 PowerKord™

The Evolution-300 PowerKord™ uses twice as many woven conductors as the Evolution-100 and is perfect for use with any Hi-Fi component, from sources, preamps and through to power amps. It is also effective when used with any of our mains extensions including the top-of-the-range Signature PowerBlock, and our Balanced Mains Units. Assess for yourself the improvements it can make (our money-back guarantee gives you 60 days to try it out).

The range has evolved

The new Evolution range of PowerKords feature Kimber’s new high purity copper (higher than in the previous PowerKord models) and our new earth arrangement which reduces the amount of noise induced into the earth by 20 times over the previous model. They really are an evolution of the design that we've loved for the past three decades and are the best performing PowerKords we've made.

Evolution-300 PowerKord™ Features

  • Evolution-300 uses sixteen separately-insulated Kimber Kable conductors, woven together to reduce Radio Frequency Interference.
  • Progressing from the established 'earth down the centre' woven cable design used in earlier PowerKords, the Evolution-300 features a new, low induced noise earth arrangement where the earth is helically wound around the outside of the weave.
  • It's not just the earthing arrangement of the new PowerKords that has improved. Kimber have been working on the purity of the copper wire used in the PowerKords' braid; the new Evolution range features a higher purity copper than the older design.
  • The Evolution-300 PowerKord™ is encapsulated in a Noise Reduction sleeving which uses a combination of two strand thicknesses to achieve flexibility and a soft, tactile feel to the cable.
  • High performance Audio Quality mains plugs and IEC connectors are used to ensure a positive, low-resistance connection to your component.

Making the right connection

Most Hi-Fi and Home Cinema components - such as your CD player or integrated amp - are fitted with a standard 10A IEC (kettle type) socket. For these, along with our PowerBars™, PowerPurifier™ and X-Blocks™, choose the W320e standard IEC (pictured above, left).

If you are fitting your cable to one of our PowerBlocks™ or older UltraPurifiers™, you'll need to choose the Wattgate W320i high current IEC (pictured above, right).

Wattgate IEC connectors are designed to make a very tight connection to the pins of the IEC socket on your equipment or on our mains extensions - the better the connection, the better the performance. Consequently, they need to be pushed home very firmly. We strongly recommend watching our instructional video before fitting to ensure your Wattgate IEC is connected properly to the equipment.

"Good Power Cable"
I've just used this cable on my tube power amp Class A without burn-in of the cable.
Already noticed a slight improvement in the speed.
However, I need to let burn-in after 300 hrs to get the full effect.

"Worthwhile Upgrade"
Bought to upgrade my LP12. In the time it took me to pluck up the courage to sever the old cable and fit this I made the mistake of fitting it to my CD player which had a Powerkord 100. It was such an improvement that I couldn't go back. Now I have the same Powerkord 300 serving both the LP12 and the CD, so the cable has to be switched when I change source. I need to buy a second 300 though if the 300 is so much better than the 100 I can't help wondering what the 500 would be like. The effect? A thoroughly re-vitalised collection of vinyl and CD's. Expectations truly exceeded. Buy one (or two). Your collection and your ears will thank you for it.
