Three gauges, one philosophy: clean current, serious copper.

The Grey Knight ENERGY is built for listeners who refuse to run a stock cord on serious gear. The same OCC single-crystal copper core, triple-layer shielding, and high-current design — now available in three conductor cross-sections so you can match the cable to your amplifier's appetite. Whether you're powering a compact integrated amp or a big Class-AB monoblock, there's a gauge that fits.

Pick your gauge

• 13 mm OD / 2.5 mm² — the entry point. Three 2.5 mm² OCC copper cores in a 13 mm jacket. Ideal for source components (DAC, streamer, CD player), preamps, and low-current integrated amps.
• 17 mm OD / 4.65 mm² — the sweet spot. Nearly double the copper per core, sized for mid-power amplifiers and active speakers where you want headroom without the bulk of the 19 mm.
• 19 mm OD / 6.15 mm² — the heavy hitter. Three 6.15 mm² cores for big Class-AB power amplifiers, power distributors, and any gear that draws real current. Keeps series resistance low under heavy dynamic swings.

What stays the same across all three

• OCC single-crystal copper conductors — ultra-pure, grain-boundary-minimized copper for clean current delivery.
• Triple-layer shielding — pure-copper braid + aluminum foil + high-temperature mica tape. Combined EMI/RFI rejection exceeds 98 %.
• Extra-thick PET jacket — abrasion-resistant, built for rack routing and long-term use.
• IEC C13 equipment plug + regional mains plug — fits standard IEC inlets on amplifiers, CD players, and power conditioners.
