Audio T Verdict
The IsoTek V5 Elektra provides dedicated mains conditioning for a complete six-component hi-fi or home cinema system, without asking source equipment and power-hungry amplifiers to share the same type of filtering circuit.
Four independent medium-current outlets are designed for streamers, DACs, CD players, preamplifiers and other source products. Two separate high-current outlets use a lower-resistance, two-stage network for integrated amplifiers, power amplifiers, active speakers and powered subwoofers.
Every socket receives its own power-cleaning circuit, helping reduce incoming Common Mode and Differential Mode noise while limiting electrical contamination passing between the connected products.
The complete Elektra is rated at 10A or 2,300W at 230V. The four medium-current outlets share a 5A limit, while the two high-current outlets can use the full 10A capacity within the overall system rating.
With 55dB of published RFI reduction, substantial surge protection, System Link expansion and an EVO3 Initium power cable included, Elektra provides a strong entry point into IsoTek’s component-width V5 conditioners.
IsoTek V5 Elektra Six-Way Mains Power-Cleaning System
The V5 Elektra is a full-width six-outlet mains conditioner designed for complete audio, home cinema and network-based systems.
Its internal architecture divides the outlets into two groups. Four medium-current sockets are intended for source and control products, while two high-current connections provide an appropriately designed supply for amplifiers and other demanding equipment.
Unlike a conventional extension block, every outlet has its own optimised cleaning circuit and connects independently to the central power-distribution network.
This Product Is the V5 Elektra
The current Audio T page URL and browser title incorrectly refer to the V5 Corvus.
The product options, £1,795 price, six-outlet component-width chassis and technical specification all belong to the IsoTek V5 Elektra.
Six Power-Cleaning Circuits in One Chassis
Elektra contains six independent power-cleaning networks rather than one general filter shared by every socket.
This allows IsoTek to use different circuit designs for source components and high-current equipment, while also reducing the opportunity for noise generated by one connected product to pass into another.
The approach is particularly useful in modern systems combining analogue, digital, network and high-current amplification products.
Four Medium-Current Outlets
The four medium-current sockets are designed for source and control components with relatively modest power requirements.
Each outlet uses an independent six-stage delta filter network. IsoTek publishes almost 20dB of cleaning at 1kHz and almost 40dB at 10kHz under its stated reference conditions.
The four outlets share a combined maximum of 5A or 1,150W at 230V.
Suitable Medium-Current Components
- Network streamers and music servers
- CD and SACD players
- Digital-to-analogue converters
- Preamplifiers
- Phono stages
- Turntable power supplies
- Headphone amplifiers
- Routers and network switches
Two High-Current Outlets
The two high-current sockets use a separate two-stage power-cleaning circuit consisting of choke and double-Pi filtering.
This section is designed to maintain low direct-current resistance while reducing mains noise, making it suitable for equipment with larger or rapidly changing power demands.
The two outlets share a maximum of 10A or 2,300W at 230V, subject to the overall Elektra rating.
Suitable High-Current Components
- Integrated amplifiers
- Stereo power amplifiers
- Mono power amplifiers
- Home cinema receivers
- Active loudspeakers
- Powered subwoofers
- Large televisions where appropriate
Understanding the Power Ratings
The four medium-current outlets share a 5A or 1,150W limit, while the two high-current outlets can support up to 10A or 2,300W.
These figures must not be added together. The maximum total load across the complete Elektra remains 10A or 2,300W at 230V.
Use the electrical consumption stated on the equipment or in its manufacturer specification when planning the connected system.
Do Not Calculate Load from Amplifier Output Power
An amplifier rated at 100 watts per channel does not necessarily consume 200 watts from the mains.
Use its published mains consumption or rear-panel electrical rating when calculating the total connected load.
Adaptive Gating
IsoTek’s Adaptive Gating system adjusts the level of Differential Mode filtration according to the current requirements of the connected component.
This is designed to provide useful noise reduction without applying an unnecessarily restrictive circuit to equipment drawing more power.
Adaptive Gating also forms part of the system used to reduce Differential Mode noise passing between the individual outlets.
Additional Isolation Between Outlets
Five further filter stages are positioned between the output circuits to help reduce electrical cross-contamination.
This is important because connected audio products do not simply receive electricity. Their internal power supplies can also return high-frequency noise to the distribution system.
By isolating the outlet paths, Elektra is designed to reduce the extent to which a digital component, television or switch-mode supply affects the other equipment.
Common Mode Mains Noise
Common Mode noise appears in relation to earth and often includes radio-frequency interference from wireless communications and nearby electrical products.
Routers, smartphones, computers, chargers, televisions and other connected devices all contribute to the radio-frequency environment within a modern home.
Elektra’s filtering network is designed to reduce this unwanted high-frequency energy before it reaches the connected equipment.
Differential Mode Mains Noise
Differential Mode noise appears between live and neutral and can be produced by the power supplies inside electrical products.
Digital sources, network devices and switch-mode supplies may return noise to the mains circuit even when the incoming household supply is relatively clean.
The six independent filtering networks help address incoming Differential Mode noise while reducing contamination passing between connected products.
55dB Published RFI Reduction
IsoTek publishes radio-frequency interference reduction of up to 55dB for the V5 Elektra.
The amount of reduction achieved in an individual installation will vary with frequency, source impedance, the incoming supply and the connected equipment.
The rating nevertheless provides a useful comparison with other products in IsoTek’s V5 range.
Low-Resistance Power Delivery
The V5 circuit has been designed to reduce direct-current resistance throughout the power path.
This is particularly important for amplifiers and powered speakers, where restricting current delivery can affect the equipment’s ability to respond to rapidly changing musical demands.
The high-current section combines its filtering network with a design intended to remain close to the low impedance of the incoming mains supply.
KERP Equal-Resistance Architecture
KERP stands for Kirchhoff’s Equal Resistance Path.
IsoTek uses this architecture to provide a consistent resistance and power path to every outlet, rather than connecting the sockets in a simple sequence.
This works alongside the individual cleaning circuits to provide a more controlled internal distribution system.
Fully Star-Earthed Network
The protective-earth connections reference a central point within the Elektra rather than passing from one socket to another.
This star-earth arrangement is designed to provide a consistent protective-earth path for the six connected products.
The Elektra must be connected to a correctly installed mains socket with a functioning protective-earth connection.
Silver-Plated Circuit Board
The internal printed circuit board uses twice the copper loading associated with IsoTek’s stated industry reference.
Its conductive paths are silver plated to help reduce resistance and support the current requirements of the circuit.
IsoTek also uses specially selected components with tighter tolerances and increased current handling compared with its previous EVO3 designs.
Silver-Plated 6N Copper Wiring
The internal wiring uses 2mm² multi-strand 6N oxygen-free copper, representing a stated purity of 99.9999%.
Each conductor strand is silver plated to provide a highly conductive outer surface while retaining the flexibility of multi-strand wiring.
The same broad material principles are used within several IsoTek power cables.
FEP Dielectric
The internal conductors are insulated using Fluorinated Ethylene Propylene, commonly abbreviated to FEP.
FEP offers stable electrical insulation and a relatively low dielectric constant compared with materials used in many ordinary power products.
It also provides strong resistance to heat, stress and chemical deterioration.
Sequential Surge Protection
The V5 Elektra includes IsoTek’s sequential and repeatable surge-protection network.
IsoTek specifies 67,500A of instantaneous protection and 32,500A of continuous protection.
The circuit is designed to respond progressively according to the severity of the incoming surge or voltage spike, helping protect both the Elektra and suitably connected equipment.
Surge Protection Has Practical Limits
No mains conditioner can guarantee protection against every electrical event or a direct lightning strike.
Disconnect sensitive equipment during severe electrical storms where it is practical and safe to do so.
System Link Expansion
A System Link outlet allows another compatible IsoTek power product to be connected without using an additional wall socket.
The linked units retain a common star-earth reference, helping maintain a structured power arrangement as the system grows.
System Link cables are available in several IsoTek cable ranges and should be selected to suit the connected product.
System Link Does Not Increase the Available Power
Adding another IsoTek product does not increase the Elektra’s 10A or 2,300W capacity.
The combined load of every linked unit and connected component must remain within the ratings of the Elektra, cable, wall socket and household circuit.
EVO3 Initium Power Cable Included
The V5 Elektra is supplied with a 1.5m IsoTek EVO3 Initium power cable.
The cable uses three 2.0mm² high-purity oxygen-free copper conductors and connects to the Elektra through its IEC C14 inlet.
A compatible IsoTek Premier, Sequel or higher-performance cable may be considered as a future upgrade.
Black or Silver Finish
The Elektra is available from Audio T in Black or Silver.
Its component-width chassis measures 450mm wide, 106mm high and 350mm deep, allowing it to fit many conventional equipment racks.
At 9kg, it requires a strong, stable and level supporting shelf.
Planning the Outlet Layout
Before connecting the system, record the mains consumption and connector requirements of every component.
Place source and control products on the four medium-current outlets, while reserving the two high-current connections for amplifiers, active speakers or powered subwoofers.
Where more than two high-current products are used, an additional compatible conditioner or a revised system layout may be required.

What Might You Hear?
Reducing mains noise and electrical interaction between components may help a suitably revealing system reproduce low-level musical information more clearly.
Possible improvements can include cleaner bass definition, greater separation, a quieter perceived background and more stable stereo imaging.
The scale of any change will depend on the incoming mains supply, connected equipment, existing power arrangement and resolution of the complete system.
