Audio T Verdict
The IsoTek EVO3 Sequel builds on the EVO3 Premier with optimised conductor strand geometry and a dedicated earthed oxygen-free copper shield.
Its three 2.0mm² conductors use silver-plated 99.9999% oxygen-free copper, insulated with low-dielectric FEP and supported by cotton filler and a Mylar barrier.
The braided shield is designed to reduce radio-frequency interference and Common Mode noise affecting the live and neutral conductors, making Sequel particularly appealing for source components and other revealing audio equipment.
A flexible 10mm outer diameter keeps installation manageable, while IsoTek’s moulded 24ct gold-plated connectors provide secure factory terminations.
Sequel does not actively clean or regenerate the mains, but it offers a carefully shielded connection between a compatible component and the wall supply or power conditioner.
IsoTek EVO3 Sequel 2m Power Cable
The EVO3 Sequel is a shielded power cable designed for compatible hi-fi and home cinema equipment with a removable IEC mains connection.
It sits above EVO3 Premier in IsoTek’s cable range, retaining silver-plated high-purity copper and FEP insulation while adding optimised conductor strands, a Mylar barrier and an earthed oxygen-free copper braided shield.
The standard cable is 2m long and is suitable for products including CD players, streamers, DACs, preamplifiers, integrated amplifiers, power amplifiers, music servers, televisions and Blu-ray players with the correct appliance inlet.
Check the Equipment Inlet
The standard UK EVO3 Sequel shown for this product uses an IEC C13 connector for a compatible C14 appliance inlet.
Check the equipment manual and rear-panel connection before ordering. Similar-looking IEC connections are not always interchangeable.
A Shielded Upgrade from EVO3 Premier
EVO3 Premier and Sequel share the same 2.0mm² conductor area, silver-plated high-purity copper and FEP dielectric.
Sequel moves beyond Premier through its optimised conductor strand geometry and dedicated earthed oxygen-free copper braided shield.
This makes it a logical next step for systems where greater protection from surrounding radio-frequency and electromagnetic interference is desirable.
Three 2.0mm² Conductors
Live, neutral and protective earth each use a conductor with a cross-sectional area of 2.0mm².
The conductor strands have an increased individual diameter compared with the conventional strand arrangement used in simpler cable constructions.
IsoTek describes this as optimised conductor strand geometry, designed to combine electrical performance with sufficient flexibility for normal domestic installation.
Silver-Plated 99.9999% Oxygen-Free Copper
The main conductors use 99.9999% oxygen-free copper, sometimes described as 6N OFC.
The copper strands are silver plated, providing a highly conductive outer surface while retaining the flexibility of a multi-strand cable.
This construction is used throughout the live, neutral and protective-earth paths rather than being limited to one conductor.
Parallel Geometry with a Gentle Twist
The three conductors run in a parallel arrangement with a slight rotational twist along the length of the cable.
This established geometry provides an initial defence against radio-frequency and electromagnetic interference.
The gentle twist also helps maintain a consistent relationship between the conductors while allowing the finished cable to remain flexible.
FEP Dielectric
Each conductor is insulated using Fluorinated Ethylene Propylene, commonly abbreviated to FEP.
FEP is chemically stable, resistant to stress cracking and suitable for use across a broad temperature range.
IsoTek publishes a dielectric constant of approximately 2.1, making FEP a lower-dielectric alternative to the PVC insulation commonly found in basic power leads.
Why the Dielectric Matters
The dielectric electrically separates the conductors while forming part of the cable’s overall electrical behaviour.
Insulating materials can store small amounts of electrical energy, so IsoTek selects FEP to help minimise this effect while maintaining the required safety and durability.
The insulation works alongside the conductor geometry, shielding and connectors as part of the complete cable design.
Cotton Filler
Cotton filler supports the insulated conductors and helps retain their positions within the cable.
It creates a mechanical buffer between the conductor assemblies and surrounding outer construction.
IsoTek also uses the material to help reduce mechanically induced noise and vibration within the cable.
Mylar Barrier
A Mylar wrap secures the internal assembly before the braided shield and flexible outer jacket are applied.
The layer helps retain the cable geometry and provides an additional barrier between the conductor assembly and surrounding materials.
Working with the cotton filler, it separates the FEP-insulated conductors from the PVC outer jacket.
Earthed OFC Braided Shield
Sequel incorporates an oxygen-free copper braided shield around the internal conductor assembly.
The screen is connected to protective earth within the factory termination and is designed to reduce radio-frequency interference reaching the live and neutral conductors.
IsoTek particularly identifies Common Mode noise as a target for this shielding arrangement.
Do Not Modify the Shield or Terminations
The shielding and protective-earth connection form part of the factory-terminated cable design.
Do not cut, shorten, open or reterminate EVO3 Sequel. Incorrect mains wiring can create a risk of electric shock, equipment damage or fire.
Common Mode Noise
Common Mode electrical noise appears in relation to earth and may be produced by wireless communications, switched-mode power supplies and other electrical devices.
This unwanted high-frequency energy can travel through mains wiring and between products connected to the same supply.
Sequel’s earthed braided shield is designed to reduce the cable’s susceptibility to this interference.
Radio-Frequency and Electromagnetic Interference
Modern homes contain many potential sources of electrical interference, including wireless routers, televisions, computers, chargers, smart devices and switching power supplies.
A power cable cannot remove every form of noise already present on the mains, but careful geometry and shielding can reduce interference entering through or being radiated by the cable itself.
For active mains filtering and protection, Sequel can be combined with a suitable IsoTek power conditioner.
Flexible PVC Outer Jacket
The internal construction is protected by a high-flexibility PVC outer jacket.
With an outer diameter of approximately 10mm, Sequel remains relatively easy to route behind most equipment racks.
Allow the cable to form gentle curves and avoid crushing it beneath furniture, folding it sharply or trapping it against metal edges.
24ct Gold-Plated Connectors
IsoTek terminates Sequel using its moulded audiophile-grade connectors with solid oxygen-free copper conductive parts and 24ct gold-plated contacts.
Gold plating provides a contact surface that is resistant to oxidation and tarnishing during normal use.
The moulded connector housings also provide strain relief around the cable entry and protect the internal terminations.
IEC C13 Equipment Connector
The standard UK cable uses an IEC C13 connector for equipment fitted with a matching C14 inlet.
This connection is commonly used by source components, amplifiers, power conditioners, televisions and other audio or AV equipment.
It must not be confused with the larger C19 connector used by some high-current amplifiers and power products.
Published 16A Cable Rating
IsoTek publishes a 16A rating for the EVO3 Sequel cable construction.
This does not mean that every finished connection or connected appliance can draw 16A.
The safe operating limit is determined by the lowest-rated element, including the UK plug fuse, equipment connector, appliance inlet, wall socket, power conditioner and connected component.
Follow the Equipment Specification
Always follow the electrical rating stated by the connected equipment manufacturer.
Do not replace a fuse with a higher value simply because the cable itself carries a published 16A rating.
Suitable for Source Components
IsoTek specifically identifies CD players, preamplifiers, tuners, music servers and other source products as suitable applications.
Source equipment generally consumes modest amounts of power but can still be exposed to interference entering through its power supply.
The earthed shield makes Sequel an attractive option where a streamer, DAC, CD player or phono stage is positioned among several digital and mains-powered products.
Suitable for Compatible Amplifiers
The 2.0mm² conductor area also allows Sequel to be used with many compatible integrated and power amplifiers.
Check the amplifier’s appliance inlet carefully, as higher-powered models may use a C20 inlet requiring a larger C19 connector.
The cable should also have sufficient clearance behind the amplifier to avoid placing leverage on its mains inlet.
Televisions and Home Cinema Equipment
EVO3 Sequel can be used with compatible televisions, Blu-ray players, soundbars, processors and other home cinema products.
The product must have a removable mains lead and a matching IEC C14 inlet.
Equipment with a captive lead or two-pin figure-of-eight connection cannot use this standard C13 version without unauthorised modification or an unsuitable adaptor.
Using Sequel with an IsoTek Conditioner
Sequel may be used between a compatible component and an IsoTek mains conditioner or power-distribution product.
Its silver-plated high-purity copper and FEP dielectric also share material principles used within several IsoTek conditioners.
The cable itself does not perform the filtering, regeneration, distribution or protection functions of the connected power product.
A Power Cable Is Not a Power Conditioner
EVO3 Sequel does not actively filter the mains waveform, remove direct-current offset, regulate voltage or provide dedicated surge protection.
Its purpose is to provide a carefully constructed and shielded connection between compatible products.
Where mains cleaning or equipment protection is required, combine the cable with an appropriate IsoTek conditioner or DC-blocking product.

Standard and Custom Lengths
The standard EVO3 Sequel power cable is 2m long.
IsoTek also lists custom lengths for the standard power-cable configuration, subject to availability and ordering requirements.
Choose a length that reaches comfortably without tension, sharp bends or a large coil of unused cable behind the equipment rack.
Separate System Link Versions
Dedicated EVO3 Sequel System Link cables are available in 0.5m, 1m and 2m lengths for joining compatible IsoTek power products.
These use a System Link connection at one end and either a compatible C15 or C19 IsoTek connector at the other.
They are separate products and should not be confused with the standard UK wall-plug-to-C13 cable described on this page.
Cable Routing
Where practical, keep the power cable separated from tonearm cables, phono leads and low-level analogue interconnects.
If power and signal cables must cross, crossing them at approximately a right angle can reduce the distance over which they run alongside one another.
Keep the cable away from sharp edges, hot heatsinks and areas where it could be stepped on or trapped.
Installation Guide
- Switch off the connected equipment
- Disconnect the existing power cable
- Confirm that the equipment uses a C14 inlet
- Check that the 2m cable reaches comfortably
- Inspect the cable and connectors before installation
- Insert the C13 connector fully into the equipment
