NAD Electronics C399 Integrated Amplifier (Solid State) Nad c399 in excellent condition With the bluOS module installed And the full Dirac Live room correction registered and paid for The C 399 employs NAD’s Hypex HybridDigital nCore amplifier circuitry, which until now has been available only on Masters Series amplifiers. Its digital section is built around a 32-bit/384kHz ESS Sabre DAC, the same chip used in NAD’s acclaimed M10 and M33 Masters Series amplifiers. The C 399 is the first amplifier to incorporate the latest generation of NAD’s Modular Design Construction (MDC) technology.
The NAD C399 is a standout in the Classic Series, widely praised for its Masters Series-derived HybridDigital nCore amplification and audiophile-grade ESS Sabre DAC. Listing at A$2,200, this unit sits just above the 75th percentile of A$2,172 for recent AUD comparables, making the price ambitious but not unreasonable given the “excellent” condition and the amplifier’s high-end capabilities like 180Wpc output and Dirac Live support via optional MDC2 modules.
This is a worthwhile buy for anyone seeking a versatile, future-proof integrated amp that excels with vinyl, streaming, and home theater via HDMI eARC. The C399’s low distortion, tight control over power-hungry speakers, and modular upgrade path via dual MDC2 ports offer meaningful long-term value. At this price, it’s a solid opportunity for a well-regarded, clean unit—especially if it includes original accessories and shows no signs of the typical wear found in older used amps.

NAD Electronics was founded in 1972 in London by a group of European audio importers frustrated with the hype surrounding Japanese hi-fi products. Led by visionary American executive Martin L. Borish and brilliant engineer Bjorn Erik Edvardsen, the company emerged from a quest to deliver high-performance audio at accessible prices. Their breakthrough came with the NAD 3020 integrated amplifier, the best-selling hi-fi amp in history, which embodied a philosophy of stripping away non-essentials to prioritize pure sound quality.
The brand focuses on core hi-fi categories, excelling in amplifiers—pioneering Class A/B, Class G, and hybrid digital designs—alongside integrated receivers, AV processors, turntables, CD and cassette players, and modern streamers. While not venturing into speakers, headphones, or cables, NAD emphasizes source components and amplification that integrate seamlessly into home theater and custom installation setups, always upholding principles of innovation, simplicity, performance, and value.
Today, as part of Canada's Lenbrook Group and sold in over 80 countries, NAD holds a commanding mid-tier position in the market, revered by audiophiles for affordable excellence rather than ultra-high-end excess. Its "Truth in Power" legacy earns cult status among knowledgeable buyers seeking reliable, award-winning gear that punches above its price, blending vintage heritage with contemporary streaming and hybrid tech.
