A brilliant engineer and visionary, he has emerged as the torchbearer for innovative Class D designs, largely through his unique applications of Gallium nitride (GaN) transistor technology specific to high-end audio amplification. Each of his product examples utilizing this technology (Tempo di GaN, Audion MkIII, Vivace, Gran Vivace, and the Solo) has significantly and uniquely shortened the bridge between live music and the recorded medium. AGD's most recent addition to this objective, the DUET, narrows the divide all the more, offering, among several new applications, the first compact monoblock amplifier utilizing 100% Gallium Nitride power MOSFET for both the output stage and the power supply
