The MCRU Pinnacle Mains Power Lead

From: £1,265.00

  • Based on 30+ years experience
  • Our best mains lead solution
  • This is not just “another” mains lead
  • Get one step closer to the live sound



The Pinnacle mains lead is the result of our 30+ years experience with the mains and related components. It encompasses everything we have learned about providing your equipment with the best possible mains feed.

The Pinnacle contains a host of our specialist tweaks many are “under the bonnet” so to speak and nothing has been spared in the quest to provide the best mains lead available today.

Each component from the cable, to the filtration in the central enclosure, fuse, earthing, filtering the mains plug and IEC connector and how the internal wires are terminated has been tested and tweaked to be the best it can be.

Our meticulous attention to detail results in a class leading product that will offer tangible sonic improvements no matter where it is used.

The Pinnacle can be used to power mains conditioners, re-generators, balanced mains units, mains extension blocks and individual components. It works by blocking out DC on the mains which is usually as a result of switch mode power supplies from fridges, freezers, microwaves etc, DC blocking provides instant sound quality improvements proven by customer feedback, the Pinnacle also incorporates some sophisticated mains filtering to further enhance performance. Because we have used audiophile quality cable designed specifically for hi-fi use and our specially chosen mains plugs and IEC connectors the unit functions as a superb mains power lead even without the DC blocker and filtration element.

We have found the mains lead works best when powering the entire system and we have available a different configuration to power individual components should the need arise. Available with UK | EU | AUS | USA mains plugs and standard or 16 amp high current IEC the Pinnacle will enhance your listening pleasure and put you one step closer to the artist.

We have made the Pinnacle available in 2 options, a standard version for powering individual components and a high current version for powering mains conditioners, mains re-generators and mains extension blocks.  

The Pinnacle is 2 metres long as standard, longer lengths of cable can be added on request.

Terminations available are UK | EU Schuko | USA | AUS

Some comments from an owner of the MCRU Pinnacle….

I have a PS Audio P10 power regenerator which supplies the power to all my hi-fi components.

I decided to try the high current Pinnacle power cord to supply the power to my P10.

This review is after 200 hours when I thought the cable had fully burned in.

I got the following benefits.

  •          More extended, sweeter treble.
  •          Bass, more solid and defined.
  •          A lower noise floor, enabling me to hear more detail and further into the mix.
  •          Better timing, leading edge of notes were now razor sharp and the improved timing allowed the decay of notes to be heard much clearer.
  •          The better timing also allowed the music to sound more composed and relaxed but at the same time to have more attack, a difficult trick to pull off.
  •          Timbre of instruments and voices sounded more natural.

I bought the cord on the strength of the 30 day return guarantee thinking I’d nothing to lose as I could return it if I wasn’t happy with it.

Needless to say I will be keeping the power cord as it has lifted my system to a whole new, more enjoyable level.

A word of warning, don’t buy if you expect to return it within the 30 days, because you won’t.
