Cardas Audio Iridium Power Cable

Available at Vinyl Sound in Toronto, Canada, the Cardas Audio Iridium Power cable brings genuine high-end power delivery to the accessible end of the Cardas lineup. Part of the Iridium family alongside the Iridium Speaker, Interconnect, and Phono cables, Iridium Power applies the same core Cardas design principles — Golden Ratio Litz copper conductors, cross-field geometry, and double shielding — to AC power delivery. The result is a light, flexible power cable with enough current capacity for virtually any component, from sensitive digital sources and DACs to full-size power amplifiers. Every Iridium Power cable is hand-terminated at the Cardas factory in Bandon, Oregon, USA.

Golden Ratio Engineering in a Power Cable

Cardas Audio's signature design philosophy centres on the Golden Ratio — conductor gauges scaled to 1.618:1 proportions to minimise strand interaction, eliminate standing waves, and produce the most natural, musically coherent signal transfer possible. In the Iridium Power, this approach is applied to 99.9999% pure oxygen-free copper Litz conductors in a cross-field layer geometry, insulated in a PFA (perfluoroalkoxy) dielectric jacket. A built-in toroidal filter reduces high-frequency noise on the AC line — a meaningful benefit for digital components and phono stages where noise floor matters most. The Absolute Sound praised the Iridium line for its "warmth and musicality" and "improved imaging" over its predecessors.

Frequently Asked Questions

What makes the Cardas Iridium Power cable different from a standard power cable?

The Iridium Power uses 99.9999% pure OFHC Golden Ratio Litz copper conductors — the same conductor technology found in Cardas's more expensive cable lines — combined with a built-in toroidal noise filter and double shielding. Standard OEM power cables use basic copper wire with no filtering or shielding, leaving AC noise unreduced.

Is the Cardas Iridium Power cable suitable for power amplifiers?

Yes. At 2 × 11.5 AWG, the Iridium Power exceeds the current capacity of virtually every OEM power cable included with commercially sold power amplifiers. It is equally suited to sensitive digital sources, DACs, phono stages, and integrated amplifiers.

Does the Cardas Iridium Power cable have a noise filter?

Yes. A toroidal filter is built into the Iridium Power cable, reducing high-frequency noise on the AC line before it reaches your component. This is particularly beneficial for digital sources, DACs, and phono stages where a low noise floor is critical.

What connectors does the Cardas Iridium Power use?

The Iridium Power is terminated with Cardas 3455R power connectors — soldered and crimped by hand at the Cardas factory in Bandon, Oregon. The contacts are silver/rhodium-plated solid copper for corrosion resistance and low contact resistance.

Is the Cardas Iridium Power cable compatible with all hi-fi components?

Yes. The standard IEC C13 termination fits virtually all hi-fi components including amplifiers, CD players, DACs, streamers, phono stages, and turntable motor supplies. The 11.5 AWG gauge provides sufficient current capacity for even high-draw power amplifiers.
