The NAPS 300 is a serious Naim power supply, and at £2,557 this listing looks fair-to-strong rather than cheap, landing a bit below the kind of pre-owned asking prices I’d expect for a clean 300-series PSU combo, such as £3,495 for a pre-owned NAP 300 DR with supply.
That’s why it’s worth a close look: these units are prized for the grip, timing, and drive they bring to compatible Naim systems, and the right one can be a genuine system-level upgrade. If the accessories are complete and the unit has been well cared for, the upside is good; with unknown condition, I’d mainly verify service history, connector set, and that it’s the correct matching supply for your amp before jumping in.
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.
