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.

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.

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.
