Bruno Putzeys: Head of the Class (D, That is)

You may not have heard of Bruno Putzeys but if you’re an audiophile and have purchased a high-performance power amplifier in the recent past, you might know his work. Putzey’s ground-breaking NCore Class D amplifier module, created under the aegis of Netherlands-based Hypex Electronics, is used in amplifiers from ATI, Marantz, Jeff Rowland, and Bel Canto, to name a few. That Morris Kessler, founder of ATI and long-time champion of Class AB amplification, chose NCore for his new AT527NC and AT524NC amplifiers, is telling. Both models received Sound & Vision’s Top Pick designation, earning five stars in the Performance category, suggesting designs that are a far cry from Class D devices of just a few years ago. We tracked down Putzeys, now CTO at Kii Audio, to learn more about the new Class D and the apparent revolution he has started.
