Allmaier Hannes

Hannes Allmaier studied theoretical physics and actually spent at least as much time on audio circuits, speaker design and acoustic theory as on his PhD. Instead of becoming a serious scientist he later entered a company formerly known as acoustic competence center (ACC), where he works on vibroacoustic, even psychoacoustics and friction related research topics for the automotive industry. Despite his adventures in active dipoles, active crossovers, power amps and restoring old gear, his longest lastingpassions are turntables and phono stages.
