About SteinMusic
Stein Music Pro GmbH was founded in 1982 by Holger Stein in Mülheim an der Ruhr and is a manufactory for high-end audio systems. The company develops and manufactures horn loudspeakers, amplifiers, phono components, room acoustics elements as well as accessories such as sound optimizers, isolators and power accessories in its own workshops. The product range is divided into the three lines Stateline, HighLine and TopLine and also includes custom-made products according to individual customer requirements. Every product goes through the entire process from conception via prototype construction to final assembly and subsequent quality assurance in-house. The family-owned company trains its own staff and operates a showroom in Mülheim with listening appointments by arrangement. The products are distributed worldwide via dealers and partners, among others through the Canadian partner Hearken Audio.
