The power cable that pulls the curtain off your amplifier.

The Grey Knight MKII is built for listeners who've realized the stock cord is the last bottleneck between their amp and the wall. Three 4 mm² OCC silver-plated copper cores, a 16 mm OD, and dense braid shielding move serious current while keeping grunge out of the audio band — the kind of cable that makes bass definition and soundstage depth suddenly "click."

Why this cable earns its place in your rack

• 3 × 4 mm² OCC 5N silver-plated copper core — three independently insulated 4 mm² conductors (live / neutral / earth) of single-crystal, ultra-pure silver-plated copper. More copper per meter than typical "audiophile" cords means lower series resistance and better dynamic current delivery.
• High-density braid shield — a continuous copper braid surrounds all three cores, shunting EMI and RFI to earth before they reach the audio path. Background goes black; micro-dynamics surface.
• 16 mm outer diameter — substantial enough to feel serious, still flexible enough to route behind a rack without fighting it.
• PTF power-filter geometry — the three-core lay and shield geometry act as a passive filter, taming high-frequency hash without smearing transients.
• CE certified, carton-box packed — safety-rated for mains voltage; arrives individually boxed, ready to terminate or use as-is.
