He is a member of the Audio Engineering Society and has taken out a number of audio-related patents, including for a "crossover displacement circuit".[1][6]
He has worked with several major companies, including Cambridge Audio, TAG-McLaren Audio, and Soundcraft Electronics.[7] Circuit Cellar website described him as a 'renowned audio specialist' when discussing a design he created for Elektor magazine.[8] He developed the concept, accompanied with a practical design, of a "blameless" amplifier in which all the main sources of distortion for a pure Class B amplifier are reduced to negligible levels, to challenge the notion that such a topology is not suitable for Hi-Fi audio.[3]
Self's books have been well received. His Audio Power Amplifier Design Handbook was recommended by Walt Jung and described as "famous" by audio website hifisonix.[9][10] The second edition of his Small Signal Audio Design received a very positive review in Sound on Sound magazine.[11]
