Over a period of several years I have interviewed audio luminaries. It started when Ed Dell asked me to go to Munich to interview Erno Borbely, and one led to another. Several of them can be read here online, courtesy AudioXpress.
Interview with Erno Borbely for AudioXpress journal. Erno has written many articles for Audio Amateur and later for AudioXpress, and has advocated JFET-based, often open-loop, audio circuits. He cut his audio teeth designing power amps for David Hafler. A great read.
Interview with Nelson Pass for MultiMediaManufacturer (Feb 2010). Another audio designer who has his own ideas of how an audio amp should sound, and his customers seem to agree. Nelson also has a DIY-dedicated website passdiy.com and writes also for AudioXpress.
Interview with Jan Lohstroh, who together with Matti Otala developed the famous anti-TIM amplifier that is still being discussed (and criticised) to this day.
Interview with Siegfried Linkwitz, the man who gave name to the Linkwitz-Riley crossover filter, and whose influence on the development and evolution of speaker design can hardly be overestimated.
Interview with Aalt-Jouk van den Hul, famous for his state-of-the-art phono cartridges but also from his developments of non-metallic audio-cables.
Interview with Edward T Dell Jr. who has been an inspiration for me, first as an author, and later until now, as a publisher. A man with a fascinating life story.
Not strictly interviews, but visit reports/articles I did as well:
My one and only AES publication: Novel feedback topology obviates the need for high loop gain, J. M. Didden, AES preprint 4597, 103rd Convention, Sept 1997. In hindsight, it wasn't really brilliant, but as they say, participation is more important than winning ;-)
We visit Mundorf is the report of my visit to the Mundorf brothers, on the request of Ed Dell, when Mundorf was still trying to counquer a spot for themselves in the audio scene.
I also found out that in 1997, John Atkinson of Stereophile referenced an article of me in Audio Amateur "Negative feedback - curse or blessing". I seem to support no one less than Martin Colloms! ;-)
