This is a buyer’s market for this model at £552: with recent comparable asking prices centered at £595, and the 25th percentile at £586, this sits below the low end of the recent range and looks like a strong deal rather than just fair value.
The appeal of this amp is straightforward: the Nait 5si is widely liked for its punchy, rhythmically assured sound and easy system-matching, so a clean example can be a very satisfying step-up integrated. At this price, the main upside is simple value if it’s working properly and comes with the usual essentials; I’d just want confirmation of basic functionality and condition, since the listing is priced low enough that any genuine issue would matter.
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.
