• Naim NAP 500 with Power Supply – The Naim NAP 500 with Power Supply is a flagship Class AB stereo amplifier offering exceptional current delivery, speed, and low-noise performance for uncompromising reference-level systems.
• Dual-Chassis Reference Design – Its dedicated 500PS power supply isolates regulation from the amplifier stage, significantly reducing noise floor and enhancing clarity, dynamic expression, and overall musical transparency.
• Advanced Output Topology – Using wide-bandwidth output devices and rigorously matched components, the amplifier maintains impressive control over complex speaker loads while delivering deep bass authority and refined microdynamics.
• Precision Mechanical Engineering – Featuring Naim’s anti-resonant casework, suspended PCBs, and meticulous shielding, the system minimises vibration interference to preserve low-level detail and maintain long-term performance stability.
• Dimensions – Amplifier: approx. 432 mm (W) × 160 mm (H) × 374 mm (D). Power supply: approx. 432 mm (W) × 160 mm (H) × 374 mm (D). Ideal for full-sized hi-fi racks.
• Weight – Amplifier approx. 25 kg; power supply approx. 25 kg. Robust construction contributes to improved damping, mechanical stability, and enhanced sonic purity.
The timing is favorable: this is an established, top-tier Naim power amp from a mature generation, so you are buying into a proven reference rather than gambling on a brand-new platform shift. At S$17,800, it sits above your recent market median of S$15,322 and also above the 75th percentile of S$16,900, so I’d call it ambitious, though not wildly out of line for a very_good example.
What makes it worth a serious look is the NAP 500’s reputation for control, drive, and that big, effortless Naim presentation that suits revealing systems and demanding speakers. If the listing is clean and complete, the upside is owning one of Naim’s flagship stereo power amps without paying retail; but at this price, I’d want confirmation of service history, included power supply, and originality of parts, since these are the details that matter most on a high-value used amp.

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.
