The IsoTek V5 Sigmas Mains Conditioner is an essential addition to any high-quality audio or audio-visual system. This innovative product offers a full system upgrade for all your electronics, including TVs and projectors. With its advanced design and unique features, the V5 Sigmas is a significant step forward from its EVO3 predecessor.
The V5 Sigmas boasts a total of seven optimised power cleaning circuits that are specifically designed to remove both Common and Differential Mode mains noise. This results in a reduction of up to 80dB in RFI, ensuring that your audio or AV system performs at its best. Additionally, the product features four independent outlets for source components and three high-current outlets for power amps, active subwoofers, active loudspeakers, and even modern TVs.
One of the standout features of the V5 Sigmas is its fully star-earthed network, which provides added protection from dangerous power surges and voltage spikes. The product also comes with a solid core Ohno Continuous Cast copper silver-plated internal wiring with FEP virtual air dielectric, ensuring excellent performance and reliability.
The V5 Sigmas is not only a power conditioner but also a distribution system, which makes it a highly functional and cost-effective upgrade for a complete high-end audio system. With its KERP technology, the product ensures equal resistance and power delivery to all outlets, resulting in an improved sound stage, three-dimensional imaging, bass articulation, and overall performance.
In addition to its exceptional features, the V5 Sigmas is also designed to be user-friendly and convenient. It comes in a compact size measuring 445mm in width, 305mm deep, and 150mm high, making it easy to fit into any system setup. The product also features a System Link outlet, allowing you to connect multiple units together and maintain a starred earth reference.

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
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 synergises with the range of IsoTek power cables. One critical but overlooked area, is maintaining commonality of design and material properties though 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.
