£919 is below the 25th percentile of the recent GBP comps, so this reads as a strong deal rather than just a fair ask. Against a median used price of £1,025 and a 75th percentile of £1,321, it sits on the buyer-friendly side of the market, leaving room for negotiation only if anything is missing or misdescribed.
That makes it worth a close look because this is a well-regarded mains conditioner for systems where noise floor, dynamics, and overall calm matter. In good condition, it’s the kind of box that can be a genuinely audible upgrade and tends to hold interest among experienced buyers. At this price, the main things to verify are straightforward: it powers up properly, all outlets and any original accessories are present, and there’s no evidence of abuse or amateur repair.
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.
