Designed for Power Amps and Power Conditioners
Ultra-High Harmonic Resolution
Accurate Dynamic Control
8 Gauge Cryo-Alloy Conductors
Rhodium/Silver over Tellurium Copper Connectors
Handcrafted in the USA
The award-winning Black Diamond represents a new era in the Phoenix series power cord design, with ultra-high harmonic resolution, breathtaking imaging and transparence and accurate dynamic control. The Black Diamond is especially suitable for power amps and power conditioners, where high capacitance, dead-neutral tonal balance and harmonic complexity are essential to produce a vivid soundstage and controlled dynamics for a refined musical presentation.

The Black Diamond Powercord is a hand-built power cord with the cryogenically treated Rhodium-plated Tellurium Copper PowerPhase IEC Connector and AC Plug. Each of the #8 AWG high-purity Cryo-Alloy conductors is wound in a proprietary geometric design. Each strand within the lay of the conductors is individually insulated with velocity-matched Teflon dielectrics. The Black Diamond is 100% protected from invasive EMI and RFI with heavy-gauge copper braid shielding. The power cord body is sheathed with double layers of abrasion resistant mesh sleeve for maximum durability and optimal flexibility. All of the wire and connectors used to build the Black Diamond are cryogenically treated in our custom cold fusion deep-immersion process at -315 degrees Fahrenheit (-192 C) to structurally align and fuse the metallurgical molecular structure of the conductive metals for optimal sonic performance. Available in lengths 3-10ft. Contact us for pricing.
