When your amplifier is hungry for current, feed it properly.

The Grey Knight ENERGY is engineered for high-current, high-energy power delivery — the kind of cable that lets a big Class-AB amplifier or a power-hungry integrated amp breathe freely instead of choking on a stock cord. Three 6.15 mm² single-crystal OCC copper cores carry serious amperage, while a triple-layer shield keeps the audio path clean.

Why this cable matters

• 3 × 6.15 mm² OCC single-crystal copper core — three independently insulated conductors of ultra-pure, single-crystal oxygen-free copper. The generous 6.15 mm² cross-section keeps series resistance low even under heavy dynamic swings, so bass stays tight and transients stay fast.
• Triple-layer shielding — high-density pure-copper braid + aluminum foil + high-temperature mica tape. The combined anti-interference coefficient exceeds 98 %, shunting EMI and RFI to earth before they contaminate the audio band.
• 19 mm outer diameter, extra-thick PET jacket — substantial build that feels like it belongs on serious gear; the abrasion-resistant PET skin survives rack routing and stage use.
• Two conductor versions — choose STANDARD (pure OCC copper) or UPGRADER (OCC copper with silver enhancement) to match your budget and sonic preference.
• US / EU / AU plug options — pick the mains standard for your region.

If your gear draws real current, the ENERGY is the cable that stops it from being starved at the wall.
