The AudioQuest NRG-525 is a mains cable sold by the metre for custom builds. It is specifically designed for professional installations and cable runs built into the fabric of a room.
The AudioQuest NRG-525 is built from three 2.5 mm² LGC (Long-Grain Copper) conductors.
The aluminium shield is tied to a 0.5 % silver-plated drain wire, which efficiently blocks electromagnetic interference (EMI) and radio-frequency interference (RFI).
The jacket is made of tough black PVC with green stripes. Its 11 mm outer diameter gives the cable excellent flexibility.
The NRG-525 is certified for use in professional areas and integration applications. It must, however, be installed by a professional or by a suitably qualified person, using the plugs and connectors of your choice. The full range is available on the AudioQuest brand page.
FAQ: Everything you need to know before buying the AudioQuest NRG-525 by-the-metre power cable
Does the NRG-525 come with its connectors?
No: this cable is sold by the metre for custom builds. The mains plug and the IEC connector are chosen separately, according to the equipment being powered and the result you are after. Brands such as Furutech are among the references most commonly used for this kind of build.
How many metres should I order?
The cable is priced by the metre, which lets you tailor each run precisely instead of putting up with standard lengths. Measure the actual path between the unit and the power source, allowing for the route behind the rack. Our guide on building a complete Hi-Fi system covers the layout of the installation as a whole.
Do I need to be qualified to assemble it?
Yes. The NRG-525 is certified for professional and integration use, but it must be fitted by a professional or by a suitably qualified person. This is not a ready-to-use cord: wiring live, neutral and earth has a direct bearing on the safety of the installation. If you would rather have an assembled and tested cord, browse our audio cables and power filters section.
Is the shielding enough in an electrically noisy environment?
The NRG-525 combines aluminium shielding with a 0.5 % silver-plated drain wire, a pairing intended to block both electromagnetic interference (EMI) and radio-frequency interference (RFI). Its PVC jacket and 11 mm outer diameter also keep it very flexible, which helps in the tight cable routes described in our advice on positioning Hi-Fi equipment.
