LessLoss C-MARC Prime Power Cable Schuko/IEC

The LessLoss C-MARC Prime is a high-end power cable that cancels out interference itself, through counter-wound copper strands, instead of merely shielding against it. It's the entry point into the C-MARC family – and for many systems, already exactly the right level.

Honestly: most devices are still hanging off the grey cable the manufacturer throws in for a few francs. The Prime is the answer for anyone who wants to know what their source can really do with a clean power supply – without hanging a fortune on the rack right away.

Why the C-MARC Prime?

C-MARC stands for Common-Mode Auto-Rejecting. Each of the 192 hair-thin, individually lacquered copper strands per pole winds in a spiral around a core of combed cotton – and for every clockwise winding there's an exactly mirrored counterpart. Whatever interference gets picked up from outside cancels itself out at the ends. No filter components, no boxes on the cable: the geometry does the work. It's elaborate to manufacture, but physically sound.

What you get

A cable with 7.07mm² total cross-section that's still flexible to route – the fine textile braid doesn't cause any fuss behind the rack. It's terminated with transparent IeGO Dreamworks connectors with gold-plated contacts and strong spring contacts that sit snugly. Sonically, owners mostly describe more calm in the background and a more relaxed, more flowing presentation.

Who's the C-MARC Prime for?

Ideal for sources: streamers, DACs, CD players, and preamps where the current draw is moderate. Also as a first step before you consider pricier levels. Honestly: for powerful power amps with high current demand, the C-MARC Classic with double the cross-section is the better choice. And a power cable doesn't fix a poorly matched system – it brings out what's already there.

Our verdict

The Prime is the most honest entry ticket into the world of C-MARC cables: well thought-out technology, clean workmanship, a price that keeps things sensible. Anyone at HD Zürisee in Wädenswil asking about a first serious power cable often ends up right here.

Frequently asked questions

Which devices is the LessLoss C-MARC Prime suited for?

It brings the most benefit on sources such as streamers, DACs, CD players, or preamps. These devices draw little current but are sensitive to interference from the mains. For large power amps, we recommend the C-MARC Classic with double the cross-section instead.

Does the Schuko plug fit a Swiss outlet?

Not directly into a Swiss type T13 wall outlet. The Schuko plug is designed for Schuko sockets, as found on many high-quality hi-fi power strips and power filters. If your device connects directly to the wall, talk to us – we'll check with the Swiss distributor which plug variant is possible.

Which length should I choose?

As short as possible, as long as necessary. Measure the route from the power strip to the device, including cable routing, and add a bit of slack. Up to 2 metres, the Prime costs the same; beyond that, the price increases. Other lengths are available on request.

Why buy the LessLoss C-MARC Prime at HD Zürisee?

Because we tell you honestly which device benefits most from a better power cable – and where it doesn't. We know the power supply of systems from long practical experience, clarify plug and length in advance, and help with the integration. Call us, write to us, or use WhatsApp.
