Transparent Audio OPUS Power Cord

The Opus Power Cord is the top of Transparent’s power cord hierarchy, engineered specifically for high-current, high-resolution amplifiers in TRANSCENDENT-tier systems — the systems where source, preamp, and amplification are already reference-class and cable-level noise floor becomes clearly audible. Every element is scaled for the demands of powerful amplification: the heaviest OFHC (Oxygen-Free High-Conductivity) conductor bundle in Transparent’s power line, the most precise filter-network calibration to cable length and inherent electrical properties, and the most massive termination hardware, all packaged in a beautifully contoured carbon-fiber network module filled with epoxy resin to damp vibration and resonance.

The Transparent filter network reduces AC line noise to previously unachievable levels and takes the length of the cable and its inherent electrical properties fully into consideration during calibration — the same custom-per-length principle Transparent applies to its interconnects and speaker cables, executed here at the top of the power cord range. Precision-torqued IEC and AC plug hardware ensures unrestricted, stable current transfer under the demands of powerful amplifiers; IEC and AC plug orientation is customized per order to fit the actual rack layout the cord will live in. The performance step over XL Power Cord typically shows up as a further quieting of the noise floor and cleaner leading-edge transient handling under high current draw — the character reference-class amplifiers are designed to reveal.

Opus Power Cord is designed for TRANSCENDENT-tier systems, specifically the amplifier side of the power chain. For source components in the same system, use Opus Power Cord Source — the smaller-diameter, more flexible cord engineered for the flexibility demands behind a rack of streamers, DACs, disc players, and preamplifiers. That two-cable strategy (Opus Power Cord for amps, Opus Power Cord Source for sources) is Transparent’s canonical layout for TRANSCENDENT-class power. Opus Power Cord comes standard with the Opus PowerIsolator when the two are ordered together. Warranty registration extends the standard limited warranty to lifetime for the original owner.

Power cords at the Opus tier reveal their difference over XL in the actual system, at the actual rack, under real amplifier current draw — the noise floor and transient behavior that separate Opus from XL are not audible in bench tests, only in a settled room with familiar recordings. Walk in during business hours or book ahead if the audition needs the actual amplifier in place and the system given time to settle.
