IsoTek EVO3 Optimum Power Cable

The IsoTek EVO3 Optimum is a top-tier power cable: ultra-pure OCC copper (Ohno Continuous Casting, solid single-core) with silver-plated conductors and an FEP helix that forms a virtual air dielectric.

Here IsoTek switches from OFC to OCC conductor: long-crystal Ohno Continuous Casting copper with silver plating. An FEP helix is wound around the conductor, then an FEP tube is extruded over it – an air gap forms between conductor and insulation, the Virtual Air Dielectric with minimal capacitance.

Why the EVO3 Optimum?

Because the solid OCC single-core and the virtual air dielectric allow extremely low-distortion power delivery. The grounded OFC shield wards off common-mode interference, and the 24-carat gold-plated OFC connectors keep the contact clean for years.

What you hear

A very low noise floor, a large, airy soundstage and excellent micro-dynamics. The finest details emerge without the sound becoming analytical.

Who is the Optimum suited for? (and who not – plain talk)

For serious high-end systems and high-current components – large power amps, active speakers, the Ultimate conditioners. Plain talk: on a smaller system it's overkill; there the Sequel or Elite gets you a better ratio.

Our verdict

The step into true top-tier class: OCC single-core, virtual air dielectric, uncompromising build. For high-end systems that are now taking the foundation seriously.

Frequently asked questions

What's the difference between OFC and OCC on the EVO3 Optimum?

From the Optimum upward, IsoTek uses OCC copper (Ohno Continuous Casting) instead of OFC. OCC has long crystals and a solid construction, which lowers resistance. Together with the virtual air dielectric, this results in an especially low-distortion power delivery.

Which version should I choose?

The Optimum belongs in front of power-hungry devices (often C19). For coupling two IsoTek devices, link versions with C15 or C19 connector are available in 0.5 / 1.0 / 2.0 m – it's included as the connecting cable with the EVO3 Super Titan.
