Auditorium 23 was established in 1980 and is owned and operated by Keith Aschenbrenner. Keith is largely unknown in the USA HiFi scene, except among those in the audio underground who are knowledgeable about the early history of the SET movement in France and Germany; or those hip to the glories of single-ended triode amplifiers, Platine Verdier turntables or the magnificent & historic Siemens Klangfilm loudspeakers (which have made a few select appearances at US HiFi shows in the last couple of years). At home, Keith has achieved the status of cultural audio icon over the years. His admirers refer to him as theTube Apostle of Germany for his trials, tribulations and ultimate success in introducing fellow German HiFi and music lovers to the glories of the combination of vinyl playback, singled-ended-triode (SET) amplification and high- sensitivity loudspeakers, all built using the best principles of classic designs. I get the impression that Keith is a little uncomfortable with the domestic notoriety bestowed upon him, preferring instead to modestly play it down by viewing himself first and foremost as an audio everyman and music lover - just like you and me.
You're probably curious about where the name Auditorium 23 came from and what it means. Keith explained. "We wanted to be a HiFi auditorium that functioned like a music auditorium: A place where we could gather people before a small stage and set up equipment as a way to introduce them to it; a place where people could sit, relax and hear musical performances while enjoying a cup of coffee."
