Alberto Guerra took a dive into high-end audio using his background in the development of GaNFET transistors as his springboard to success. In bold strokes he premiered his Avant-Garde style Vivace monoblock putting out 100 Watts into 8 Ohms, 200 Watts into 4, and the Art Deco-like simulated tube design of The Audion, another monoblock putting out 85 Watts into 8 Ohms and 170 Watts into 4 Ohms. The clever ploy of inserting the power modules into the glass of vacuum tubes and featuring them prominently in his designs, allowed for easy user upgradeability when new power circuits were developed.
