Commercial Naim Audio NAC 252 Power Supply Classic Naim Audio control and clarity. Like many of our products, the NAC 252 stems from good stock: it descends directly from the NAC 52, still one of the finest preamplifiers ever made. Capable of exceptional clarity, its power supply components reside in a separate enclosure: the SuperCap power supply unit. This ensures optimum isolation from electromagnetic interference and provides each of the ten audio circuits with an independent, fully regulated supply voltage. Additionally, separate power supplies for the digital control and switching circui
Compared with buying a new preamp at this level, US$4,611 is a touch above your local median used ask of US$4,331 and above the 75th percentile at US$5,022. That makes it a fair-to-ambitious ask rather than a bargain, but not absurd for a desirable piece in a strong market.
What makes it appealing is the NAC 252’s reputation for rhythm, scale, and poise: it’s one of Naim’s most respected linestage preamps and can anchor a serious system for years. At this price, I’d want confidence in service history, remote, power supply compatibility, and clean operation, but if it’s been well cared for, this is still a credible buy for someone who wants a long-haul reference-grade preamp rather than a stopgap.

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.
