ISOL-8

What ISOL-8 does

ISOL-8 Teknologies Ltd. is a UK-based, founder-owned manufacturer of high-performance power conditioning and distribution equipment for hi-fi and audio-visual systems. Founded by Nic Poulson, a former BBC sound engineer who also founded sister company Trilogy Audio Systems, the company designs and manufactures its products in the UK under a five-year guarantee. Its portfolio is organised into three tiers — High Performance (InLine, PowerLine family, MiniSub variants, VMC1080), Audiophile (SubStation range, IsoLink cables, PowerStation), and Custom/Professional (6 Way Sequential, Connect System, The Grid) — plus the Prometheus audiophile DC power supply. Core technology rests on two proprietary designs: Transmodal filter technology, which blocks common and differential mode noise without shunting it to ground, and the Axis DC blocking circuit, which re-balances the mains waveform to prevent transformer saturation and acoustic hum. Multiple dedicated filter sections per outlet are used to prevent cross-contamination between connected components.

The company sells exclusively through a B2B2C channel: UK retailers (including named Reference Dealers), international distributors in 35+ countries across Europe, North America, and Asia-Pacific, and dedicated custom installation professionals in the UK and selected international markets. Pricing is not publicly disclosed, though the company recommends spending approximately 10% of system cost on power optimisation. Revenue is generated through hardware sales of mains conditioners, power distribution units, power cables, and DC power supplies, with no disclosed external funding, no public listing, and a headcount in the 11-50 range. Recent strategic activity has centred on product line extension rather than category expansion, with 2025 launches of IsoLink VERTEX and VECTOR power cables and the PowerLine Extreme, and earlier introductions of the Prometheus DC supply and SubStation LCX.
