Ever since hearing, aged 16, two pairs of EL84's make short shrift of a shiny new solid state amplifier, Bruno wanted to know why things sounded the way they did instead of how they were supposed to. The ensuing expedition past all the stations of valves vs FETs vs transistors, analogue vs digital and their respective proponents gave him a keen eye for paradoxes, red herrings, logical fallacies, nonsequiturs and plain weirdness. He is probably best known for inventing the UcD and Ncore class D amplifier circuits and designing the Grimm Audio LS1 loudspeaker. Further work includes various digitally and analogue controlled class D amplifiers, noise shapers and modulation methods, DSP algorithms, high-performance discrete AD/DA converters and analogue signal processing circuits. What little time remains he devotes to writing and giving lectures in the hope of furthering rationality in audio. In these presentations and articles he shows skeptics what to measure before judging subjectivists to be wrong and demonstrates to audio mystics just how much subjective audio experience is readily explained in ordinary physical, mathematical and psychoacoustical terms.
