Buyer’s market: at £3,474, this sits just below the £3,494 25th percentile and under the £3,515 median, so it reads as a strong deal rather than a merely fair ask. It’s not a huge discount, but in a market where the middle of the pack is a touch higher, this is priced with enough cushion to look attractive.
The 555 PS DR is one of Naim’s respected power supplies, prized for lowering noise, tightening timing, and letting the source gear sound more composed and authoritative. For the right Naim system, that usually means a clear, worthwhile upgrade path; if the unit is genuinely clean and complete, the value here is in getting that performance lift without paying top-of-market money.

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.
