£899 is a strong deal versus your used-market anchor: it sits below the £993 25th percentile and well under the £1,025 median, so this is priced to move rather than merely “fair.” In a market where comparable asking prices cluster above this, that leaves decent room for a quick, buyer-friendly purchase.
This is worth chasing because the Sigmas is one of IsoTek’s better-known power conditioners: a serious upgrade piece that can lower hash, improve dynamic contrast, and make a system sound calmer and more organized. At excellent condition, the upside is even better if it’s complete and well cared for, since these usually age more by handling and accessory loss than by dramatic wear. If it’s tidy and comes as expected, it reads like a solid buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
IsoTek, founded in 2001 in England by Keith Martin, emerged from a focused mission to combat poor mains power quality that hampers hi-fi performance. Martin's vision drove rigorous research into power optimization, establishing the brand as a pioneer in delivering clean electricity to audio systems. From its inception, IsoTek has prioritized innovation, with products manufactured in Europe to ensure durability and precision.
The company specializes exclusively in power conditioning solutions, including highly specialized mains conditioners and enhancement power cables. These components actively filter and purify electricity from wall sockets, benefiting amplifiers, source components, turntables, and home cinema setups without altering core audio gear categories like speakers or DACs. This narrow focus allows IsoTek to offer scalable upgrades across budgets, from entry-level to reference-grade systems.
IsoTek commands a premium position in the high-end hi-fi market as the recognized leader in clean-power technology, trusted by over 100,000 customers in 45 countries and endorsed by brands like Arcam, Marantz, and Nordost. Hundreds of awards from audio critics affirm its reputation for transformative sound improvements and equipment protection, appealing to discerning enthusiasts seeking measurable performance gains.
