This is a buyer’s market for Hypex NCx500-based amplifiers, and the A$1,900 asking price for the used Hypex NCx500 is a strong deal. A new Apollon Hypex NCx500 ST stereo amplifier carries an RRP of A$2,850, while a comparable new unit is listed around €1,290 (roughly A$2,150). On the used market, the A$1,900 price sits below the typical range, making it a genuine bargain for a well-regarded Class D amp.
The NCx500 module is prized for its 380W peak into 8Ω, ultra-low distortion (0.0006% THD+N), and 137dB signal-to-noise ratio, delivering clean, dynamic power with minimal heat. This listing offers significant upside: you’re getting near-new performance at well below new cost, with the NCOREx architecture known for reliability and sonic transparency. Unless the condition is questionable or accessories are missing, this is a compelling buying opportunity for a serious hi-fi enthusiast.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Hypex Electronics, founded in 1996 in the Netherlands, emerged from the live sound sector with plate amplifiers for loudspeakers before pivoting to hi-fi applications. Key innovator Bruno Putzeys developed the Universal class D (UcD) technology, patented through Philips, which propelled the company's early reputation for efficient, high-performance amplification. From modest origins supplying subwoofer modules and multichannel units with active crossovers, Hypex quickly gained traction among studio and audiophile manufacturers seeking superior class-D solutions.
The brand specializes in class-D power amplifier modules, power supplies, DSP solutions, and plate amplifiers, powering active speakers across hi-fi, high-end, and pro audio markets. Iconic lines like UcD and later NCore® deliver ultra-low distortion and exceptional efficiency, setting benchmarks for measured and subjective performance. While not producing complete speakers, turntables, DACs, headphones, or cables, Hypex modules form the backbone of systems from major OEM brands and enable DIY enthusiasts through Hypex Direct kits.
Hypex holds a commanding niche as a world-leading supplier in the high-end class-D segment, trusted by discerning audiophiles and professionals who demand uncompromising sound quality without traditional amp compromises. Its modules outperform legacy designs in efficiency and fidelity, positioning Hypex as the go-to for boutique builders and premium integrations, with production now in Malaysia to meet global demand.
