This is an ambitious ask: £690 sits above the £675 75th-percentile figure from 19 recent comparable listings, with the median at £592. It is not wildly out of line, but the seller is asking a clear premium for an unknown-condition example, so value depends heavily on cosmetics, service history, and completeness.
The Nait 5si remains a highly regarded compact integrated, combining lively timing, rhythmic drive, and plenty of musical involvement rather than simply chasing headline power. It makes an excellent partner for transparent, easy-to-drive speakers and is a sensible choice for a system where pace and engagement matter. At £690, insist on a clean, fully working unit with the remote, original packaging if available, and reassuring evidence of careful ownership; otherwise, negotiating toward the market median would be sensible.
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.
