This is an ambitious ask. At £1,199, it sits well above the £841 median for 26 comparable used listings and exceeds the £1,014 75th percentile, so it needs exceptional provenance or unusually complete condition to justify the premium. With the condition marked unknown, the price is difficult to recommend at face value.
The i-Supply is a useful, compact Naim accessory PSU designed to power one compatible product such as a Stageline or HeadLine, with the appropriate adaptor lead. It can bring the neat, low-noise external-supply approach Naim is known for to a compatible system, but this is a niche accessory rather than a major standalone upgrade. Before considering £1,199, confirm the exact version, original captive lead and adaptors, voltage suitability, service history, and a clear demonstration of correct operation; otherwise, negotiate firmly toward the market median.
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.
