The groundbreaking Transparent Generation 5 Power Conditioning Filter Technology introduced in the new OPUS PowerIsolator snuffs out broadband AC power line noise without restricting current or introducing phase shift. Designed to work in perfect harmony with its included 20-amp IEC OPUS Power Cord, OPI is ready to deliver limitless current and noise-free, in-phase power through 2 identical, high current, grounded, and surge protected outlets. Most other power conditioning solutions reduce some AC noise, but they also restrict instantaneous current and alter the phase of the power signal — a condition that introduces noise and shifts the tonal balance performance of the system. OPI in combination with OPUS Power Cords insures that your system is free to reveal all the dynamic complexity and energy and the pure and natural instrumental tonality encoded in your favorite music sources.


With OPI’s curvaceous carbon fiber form, there can be no mistaking its OPUS lineage. Like OPUS Speaker Cable, OPI’s epoxy-loaded, fully damped carbon-fiber carapace blocks vibrations and allows electromagnetic fields to fully expand. The OPI center of gravity is also low and wide which further insures that any excess energy broadly dissipates away from the filter circuitry. Adjustable, precision machined isolation feet reduce vibration further and come with soft or hard contact options to work more effectively on a variety of different types of surfaces.

Painstakingly constructed with multi-step measurements and circuit adjustments, the OPI filter circuit is also calibrated to the filter characteristics of the included OPUS Power Cord. OPUS Power Cord conductors serve to link the OPI filter circuit from input to output, and the filter characteristics of the OPI conductors are also an important part of the measurement process and filter circuit calibration. OPI’s parallel noise filtering circuit results in full, free, instantaneous current flow, thereby allowing your system to deliver untethered musical dynamics. Likewise, the parallel hydraulic magnetic circuit breaker provides failsafe circuit protection without limiting current.

For optimum OPUS PowerIsolator performance, use with only one component on a dedicated AC circuit and use an OPUS Power Cord for each OPI to component connection.
