IsoTek EVO3 Elite Power Cable

The IsoTek EVO3 Elite cable is a 2.0 m power cable designed for audio and video equipment. It is available with a choice of C7, C15 or C19 equipment-side connector. Seven silver-plated conductors made from 99.9999% pure oxygen-free copper are combined with an FEP dielectric.

This cable connects one audio or video system component to the mains supply. It is not a mains filter, extension lead or multi-socket power distributor. Before ordering, the most important step is to select the connector version that matches the power inlet on your equipment.

Purpose in an audio or video system

The cable is intended for CD and Blu-ray players, tuners, music servers and preamplifiers. It is also designed for use with power amplifiers, televisions and soundbars.

In a stereo system, it can connect a source component, preamplifier or power amplifier. In a home cinema system, it may be used with a video player, television or soundbar. Every separately powered component requires its own cable, so the number of cables needed depends on how many devices are being connected individually.

Conductors and layered construction

The 7 × 1.25 mm² designation refers to seven conductors, each with the stated cross-sectional area. It does not describe the cable’s overall outside diameter. The conductors are made from 99.9999% pure oxygen-free copper and have a silver-plated surface.

Silver forms the outer layer of each conductor, while copper remains the principal conductor material. A fluorinated ethylene propylene (FEP) dielectric is used around the conductors. Cotton filler occupies the spaces between the internal cable elements and forms part of the cable’s layered construction.

The design also incorporates a PVC barrier and a Mylar layer. These internal elements are enclosed by a flexible PVC outer jacket. The EVO3 Elite is therefore not simply a group of conductors surrounded by one thick, solid layer of plastic; its internal structure consists of several specified materials with distinct roles.

The connectors feature 24-carat gold plating and are described as audiophile-grade. Gold is used on the contact surfaces because it resists oxidation.

Choosing a C7, C15 or C19 connector

C7 is a two-contact, figure-of-eight equipment connector. Choose this version only when your component has the corresponding inlet. A C7 connector should not be treated as a smaller version of C15 or C19, because its shape and contact arrangement are different.

C15 has three contacts and a characteristic inlet profile. C19 is also a three-contact connector, but its housing is larger and differently shaped. These versions are not interchangeable simply because they serve a broadly similar purpose.

The equipment category alone does not always reveal which version is required. Two different power amplifiers or music servers may use different power inlets. Make the final choice by checking the physical shape of the inlet and any designation printed beside it. This direct inspection is more reliable than selecting a connector solely from the type of component.

Length and cable routing

The standard length is 2.0 m. This is suitable when the cable can reach the power point freely without being pulled tight behind the equipment. Measure the actual route around furniture, shelving and other obstructions instead of measuring a straight line through open space.

The 11 mm outside diameter matters when routing the cable through furniture openings or a tightly arranged equipment rack. The flexible PVC outer jacket makes positioning the cable easier. Even so, sufficient space should be left behind the connector for a relaxed curve. Do not force the cable into a sharp bend immediately after the connector.

If the standard length is too short or would leave an unnecessarily large loop, custom cable lengths are available. Choosing an appropriate length helps avoid tension between the component and power point while also reducing the amount of excess cable that must be stored behind the equipment.

Current rating and practical selection

The cable’s rated current is stated as 16 A. This rating is not specified separately for the C7, C15 and C19 connector versions.

Connector compatibility remains essential when selecting the cable. Length and the intended routing path should also be considered so that the installed cable is neither stretched nor left in an excessively large loop behind the system.

FAQ

Which connector version should I choose?

Choose according to the shape and designation of your equipment’s power inlet. C7, C15 and C19 are different connector types and are not direct substitutes for one another.

Is the cable suitable for both stereo and home cinema systems?

Yes, provided that the system component has the corresponding C7, C15 or C19 inlet. The cable is intended for audio sources, amplifiers and the listed video equipment.

How can I determine whether the 2.0 m length will be sufficient?

Measure the actual routing path from the component to the power point. Allow for furniture edges, shelves and the relaxed curve required behind the connector rather than relying on a straight-line measurement.

Can I order the cable in a different length?

Yes. Custom lengths are available for this model. This is useful when the standard cable would be pulled tight or would leave a large loop behind the equipment.

Why does the 11 mm diameter matter?

This measurement should be considered when the cable must pass through narrow openings in furniture. Enough space must also be provided for the cable to form a gentle curve.

What does the 7 × 1.25 mm² designation mean?

It means that the cable contains seven conductors, each with a stated cross-sectional area of 1.25 mm². This figure should not be confused with the cable’s 11 mm outside diameter.
