At £5,250, this excellent-condition Naim NAPS 555 DR is a strong deal, sitting just below the 25th percentile of £5,249 and well under the median of £5,280 from eight recent GBP listings. The "excellent" condition note implies minimal wear and likely original owner care, which justifies the asking price while still offering clear value compared to the typical used market range of £5,249–£5,369.
This power supply is a well-regarded upgrade for the Naim 555 series, delivering tighter bass, improved dynamics, and a more open soundstage that enthusiasts consistently praise. Its DR (Dynamic Range) revision adds meaningful sonic refinement over earlier versions, making it a sought-after upgrade for serious listeners. At this price, in excellent condition with no noted missing accessories, it represents a genuine buying opportunity for upgrading a 555 system without stretching into higher-tier power supplies.

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.
