Compared with buying a more substantial Naim power supply at this money, £1,250 is ambitious: it sits well above the supplied comparable market, with a £789 median and £995 75th percentile. The unknown condition makes that premium harder to justify, so this is not a bargain; a price nearer £995 would look much more comfortable.
The I-Supply is worthwhile when it is the correct upgrade for a compatible Naim component, adding dedicated power-supply capacity and potentially improving stability, timing and low-level clarity—the sort of refinement Naim users value. Before paying the premium, confirm the exact model, voltage, DIN/Burndy lead compatibility and whether the original cable and packaging are included. With clean, verified operation and complete accessories it may suit a committed system, but at £1,250 the listing needs unusually strong condition and provenance to make sense.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Naim Audio, a cornerstone of British hi-fi excellence, traces its origins to 1973 when Julian Vereker, a self-taught engineer, racing driver, and music enthusiast, formally incorporated the company in Salisbury, Wiltshire. Vereker's journey began earlier, in 1969, experimenting with tape recording and sound-to-light boxes before designing his first power amplifier in 1971. Amid the British hi-fi industry's recession, he secured a pivotal contract with Capital Radio, blending entrepreneurial grit with a passion for authentic sound reproduction that challenged conventional wisdom.
The brand specializes in premium integrated amplifiers, power amplifiers, preamplifiers, digital streamers, DACs, and compact music systems, often featuring built-in amplification for streamlined setups. While not delving into speakers—beyond a historical foray—or headphones and turntables, Naim emphasizes modular, upgradable components that prioritize pace, rhythm, and timing (PRaT), a signature sonic philosophy rooted in the "source first" approach alongside contemporaries like Linn.
Naim holds a commanding position in the high-end market, revered by discerning audiophiles for its handmade, innovative systems that deliver emotional musical engagement over mere specifications. Now part of VerVent Audio Group following a 2011 merger with Focal, it exports to over 45 countries, sustaining a cult following for resilient, influential designs that transcend economic cycles.
