The Select Series

V5 Sigmas

Both V5 Aquarius and V5 Sigmas remain one of the most cost-effective upgrades you can buy to improve your high-quality audio- or audio-visual system. Both products will improve all audio-, audio-video-, and network-based systems including TVs and projectors, it is a full system upgrade improving all your electronics unlike any other product on the market. V5 Sigmas is a significant step forward from its EVO3 predecessor. Now a seven-way mains power cleaning product featuring three high-current outlets that utilizes a lighter version of the V5 Titan’s Direct-Coupled© circuit to provide ultra-high current low impedance power for amplifiers, subwoofers, active loudspeakers, or nowadays TVs and projectors. The four remaining output sockets are medium-current for source components. Each outlet of the V5 Sigmas has its own dedicated clean power network; thus, seven power cleaners in one box! V5 Sigmas represents an extremely cost-effective way to fully upgrade a complete high-end audio system as well as offering protection from dangerous power surges and voltage spikes.

Design

The V5 Sigmas is an innovative component with a power cleaning and distribution system measuring 445mm in width, 305mm deep and 150mm high. It is a significant step up from the Aquarius and its EVO3 predecessor featuring over 35% improved amperage due to decreased resistance within the circuit design as well as 40% increase in current handling capability. This dramatically improves performance. There is improved direct current resistance (DCR) throughout the new design, bringing performance closer to the zero Ohms ideal. V5 Sigmas is seven power cleaners in one box, seven independent outlets, each one with its own dedicated clean power network. These dramatically reduce both Differential Mode and Common Mode noise. Cross contamination of connected components is also kept to a minimum due to the multiple power cleaning stages for each output socket. Most power filters join output sockets together, running each in series. This is an error as Differential Mode Noise created by your connected electronics will cross contaminate from one output socket to the next. The electrical architecture and design of V5 Sigmas is dramatically superior.

There are three high current low impedance outlets, rated at 16A, delivering 3’680W at 230V or 1’840W at 115V. These are suitable for all kinds of power amplifiers, active loudspeakers and subwoofers, nowadays TVs and feature a light version of the Titan’s Direct Coupled© circuit. The four remaining medium current outputs rated at 10A are designed for source components. These feature IsoTek’s unique Adaptive Gating © technology that autosenses the connected load, thus giving the ideal optimal clean power based upon power draw. The power cleaning network is more sophisticated than that of Aquarius.

KERP © (Kirchhoff’s Equal Resistance Path) ensures equal resistance and equal power delivery to all outlets. The internal wiring is of the highest standard; ultra-pure Ohno Continuous Cast copper solid core conductor strands with silver-plating offering low resistance and high amperage. A Fluorinated Ethylene Propylene (FEP) helix is wound around the conductor before an extruded FEP dielectric protects the conductor and creates a Virtual Dielectric of Air dielectric (FDA). This construction gives unrivalled performance and gives the ultimate low resistance, high performance internal power delivery system. Furthermore, 121’500A of instantaneous protection is provided, safeguarding valuable equipment via IsoTek’s unique sequential and repeatable protection system.

V5 Sigmas is high quality design yet highly functional and an excellent upgrade for a complete high-end audio system improving sound stage, three-dimensional imaging, bass articulation, control and a sense of extended frequency range and openness. IsoTek’s award winning Premier power cable is also included.

The internal wiring of IsoTek products synergizes with the range of IsoTek power cables. One critical but overlooked area, is maintaining commonality of design and material properties through an audio wiring loom, be it signal carrying cables or your power cable network.

V5 Sigmas also contains a System Link outlet, this is designed to connect multiple units together, maintaining a starred earth reference, and preserving the need for multiple wall outlet sockets.

Why Choose IsoTek

IsoTek is a British power optimisation manufacturer specialising in high-performance power conditioning and power distribution systems designed specifically for serious audio and home theatre applications. Founded by Keith Martin, IsoTek has become one of the most recognised names in power management by focusing on one often overlooked reality within high-end audio — every component in the system ultimately depends on the quality of the incoming AC power feeding it.

What makes IsoTek particularly successful is the way the company approaches power conditioning as a carefully balanced engineering exercise rather than simply applying heavy filtration across the entire system. IsoTek designs are developed to reduce unwanted mains noise, differential mode interference, and cross-contamination between connected components while still preserving current delivery, dynamics, and musical energy.

At HeyNow Hi-Fi, IsoTek products have consistently proven effective across a broad range of systems, from compact streaming setups through to highly resolving high-end analogue and digital installations. The improvements are often less about changing the tonal character of a system and more about allowing the existing equipment to perform with greater stability, lower background noise, improved focus, and increased dynamic clarity.

Signature Design and Sound

Manufactured in the United Kingdom, IsoTek products are engineered around proprietary filtering networks, isolated outlet architectures, carefully controlled grounding systems, and high-quality internal wiring designed specifically for audio performance. Unlike generic surge boards or mass-market power filters, IsoTek products are developed to address the unique electrical demands of sensitive audio equipment.

One of the company’s core philosophies is that different components place very different demands on the AC supply. Source components, DACs, streamers, preamplifiers, and high-current power amplifiers all behave differently electrically, which is why many IsoTek products utilise individually isolated outlet sections and carefully optimised filtering stages tailored to different device categories.

IsoTek also places strong emphasis on preserving transient current delivery and avoiding the compressed or dynamically restricted presentation sometimes associated with poorly implemented power conditioning systems. The goal is not to “soften” the sound, but rather to reduce electrical noise and allow greater resolution, dimensionality, and natural musical expression to emerge from the existing system.

The company’s range also extends into highly regarded power cables designed to complement the conditioning platforms through low-resistance conductors, controlled shielding, and optimised power transfer characteristics.

IsoTek Product Range

The IsoTek range includes power conditioners, power distribution systems, power cables, and specialised mains optimisation products designed for systems ranging from compact Hi-Fi setups through to large-scale high-end audio and home theatre installations.

Popular products including the Aquarius, Sigmas, Titan, and V5 series have become highly respected for their ability to reduce system noise while maintaining musical dynamics and long-term listening engagement. Across the range, the focus remains firmly on electrical stability, isolation, and allowing connected equipment to perform closer to its full capability.

At HeyNow Hi-Fi, Geoff and his experienced system setup team provide guidance on power optimisation, system matching, cable integration, and overall electrical configuration to ensure IsoTek products are implemented effectively within each customer’s listening environment.
