NAD Electronics and PURIFI Audio Announce Cooperation Agreement

NAD will license PURIFI's patent-pending amplification technology to create next-generation amplifier platform.

NAD Electronics, the acclaimed high-fidelity audio brand with more than 45 years of leadership in performance amplifier innovation, announced that it will be the first international brand to incorporate and launch PURIFI’s new patent-pending, class-D technology into its product family. The amplifier circuit, known as Eigentakt (meaning “self-clocking”), is the result of years of research by PURIFI into the self-oscillation behaviors in class-D amplifiers with algorithms that, when applied in control loops, improve existing designs by an order of magnitude or more. The agreement will see the two companies cooperate to adapt the Eigentakt circuit to NAD’s signature design requirements, with the intent to create a new amplifier platform for future, yet-to-be-announced products from NAD.

“The Eigentakt technology is unique,” explains Bruno Putzeys, co-founder at PURIFI Audio. “Amplifiers carrying the technology will be exceedingly indifferent to speaker load, volume level and signal content, resulting in negligible THD and IMD levels, and will feature exceptionally clean clipping.”

According to measurements by PURIFI, the Eigentakt circuit is expected to outperform any audio amplifier known, regardless of technology or class, with THD and IMD quoted as below 0.00017% at all frequencies and power levels, and the frequency response in the audio band remains within +/- 0.01 dB under all load conditions. In addition to its status as a groundbreaking technology, it also represents one of the first products to be commercialized by PURIFI, which was founded in 2014 by industry veterans and renowned audio experts Putzeys, Lars Risbo and Peter Lyngdorf.

“Our NAD design team, led by Greg Stidsen, Taresh Vadgama and including the late Bjorn Erik Edvardsen, have maintained a close working relationship with Bruno, Lars and Peter over the years. Clearly, we all share the same commitment to audio excellence, so NAD is pleased and proud to be at the forefront of adopting PURIFI’s class-leading technology,” said Gordon Simmonds, CEO of the Canada-based Lenbrook Group, owners of NAD Electronics, as well as other high-fidelity audio brands, Bluesound wireless multi-room and PSB Speakers. “Our teams are already fully engaged in the process of developing a next-generation amplifier
platform that will feature this circuitry, keeping NAD and our other brands at the forefront of
audio technology as it begins to weave into our product roadmap.”

“I have personally been involved with NAD Electronics and have known the Lenbrook team for 40 years,” said Lyngdorf, Co-Founder and Chairman of PURIFI. “NAD is the perfect collaboration partner for this new technology, and we look forward to their implementation, as we are sure it will propel the industry’s expectations for high-fidelity amplifiers.”

About PURIFI Audio
Based in Roskilde, Denmark, PURIFI was founded in 2014 by industry veterans Bruno Putzeys, Lars Risbo and Peter Lyngdorf, out of a shared conviction that truly significant improvements in musical experience can only be had by addressing technical fundamentals in electromagnetics, mechanics and acoustics. With a focus on developing and verifying accurate mathematical models to solve problems in analog and digital sound reproduction, PURIFI aims to remove all technical limitations in the enjoyment of reproduced music. Their
first contribution is a new Class-D amplifier circuit called Eigentakt.
