The device achieves world-beating performance in a high-end prosumer audio amplifier. We worked with world-leading audio experts to investigate and explore new components and techniques, considering and modelling each in turn to select the optimum solution for both multiple amplifier stages and power supply design.The quality requirements were so demanding that a completely fresh approach was needed to break the mould in amplifier design. This resulted in a suite of parameters that exceeded specification and listening tests that delighted industry experts. White paper development addressing novel techniques and methods as a consequence of investigative research with world-leading academics and industry experts published.
