IsoTek EVO3 Optimum Power Cable

Reference-Level Power Delivery with OCC Copper

The IsoTek EVO3 Optimum is a premium audiophile power cable engineered for high-performance Hi-Fi and home theater systems. Positioned above the EVO3 Elite, Optimum introduces silver-plated Ohno Continuous Cast (OCC) copper conductors with an innovative square-strand geometry designed to deliver exceptional conductivity and reliable high-current performance.

With advanced FEP insulation, an earthed OFC shield, and IsoTek’s audiophile-grade 24ct gold-plated connectors, EVO3 Optimum provides a sophisticated power connection for everything from sensitive source components to demanding power amplifiers.

Silver-Plated OCC Copper Conductors

At the heart of EVO3 Optimum are three 3.0 mm² silver-plated OCC copper conductors. Each conductor uses square-shaped strands that can be packed tightly together, increasing contact surface while providing excellent electrical conductivity.

The Ohno Continuous Cast process produces extremely pure copper with excellent conductivity, flexibility, and resistance to fatigue and corrosion.

Advanced RFI & EMI Rejection

The three conductors are arranged in parallel with a slight rotational twist to help reduce Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI).

The cable is further protected by an earthed Oxygen-Free Copper braid shield, designed to maximize rejection of high-frequency interference and help prevent common-mode noise from affecting the live and neutral conductors.

Premium FEP Dielectric

IsoTek uses Fluorinated Ethylene Propylene (FEP) insulation, selected for its very low dielectric constant across a wide frequency range.

Cotton filler provides internal strength while helping reduce microphony, while a Mylar wrap creates an additional dielectric barrier before the flexible and mechanically durable PVC outer jacket.

Audiophile-Grade 24ct Gold-Plated Connectors

EVO3 Optimum is terminated with IsoTek’s bespoke solid OFC audiophile-grade connectors featuring 24-carat gold-plated conductors. These premium terminations are designed to provide a high-quality electrical connection while offering excellent resistance to tarnishing.
