our philosophy
We add nothing to the music. We take away what lies between the recording and your room. What remains is music as it was recorded.

WHO WE ARE
A family business in its second generation
At 14, Holger Stein builds his first amplifier. The question of why two technically identical devices sound different stays with him and leads him to study physics. In 1982 he founds Stein Music Pro GmbH in Mülheim an der Ruhr.
Today Holger still develops every product himself. Gabriele Stein runs the company, Sebastian Stein is responsible for sales and marketing. Together with our team, we train our own apprentices and manufacture in-house.
Our principle
Four stations between recording and ear
Each of these stations lays something over the music. We work to remove these layers. Effective on their own, attuned to one another as a whole.

Power and ground
Calm begins with power. A clean reference point gives your system a clear, silent background.

Signal
Cables and network connections that transmit without coloring. Made on our own braiding machine.
History
over four decades
A question in a workshop became a system that today stands in listening rooms on several continents.

the first amplifier
1975
Holger Stein builds his first amplifier. The question of why identical technology sounds different later leads him to study physics.

Founded in Mülheim
1982
While studying physics, he repairs and improves amplifiers and loudspeakers for fellow students, and soon for friends and acquaintances. In 1982 he turns this into a profession and founds Stein Music Pro GmbH in Mülheim an der Ruhr.

International debut
2010
At the first AXPONA in Jacksonville, Florida, our H2 Acoustic System can be heard. Since then, magazines in Europe and the US have reported on our work.
three lines
A path that grows with you
All products are attuned to one another. They start where your system stands today and later add what is missing.
STATELINE
The entry
First steps toward more calm in the sound, easy to use.
HIGHLINE
THE NEXT STEP
More elaborate materials and craftsmanship for systems that already sound good and should reveal more nuance.
Topline
The goal
Our most elaborate execution, for systems where every detail counts.

Handcrafted in Mülheim
developed and built under one roof
From the first design through the prototype to final inspection, every step stays with us. For this we have built a high degree of in-house manufacturing: our own braiding and winding machines, CNC milling and a workshop where everything comes together.
This lets us shape every step of the process ourselves and refine it until nothing stands in the way of natural sound. We also choose materials by what they make audible.
Press
What others say about us
Over the years, journalists from Europe and the US have come to know our workshop, our work and our products. Three voices that describe who we are.
how we work
Method over chance
“SteinMusic has been in business since 1982, They are an engineering-based company, rather than trial and error manufacturer.”
Martin Justan, Audiodrom
who we are
Quiet in manner
“In my conversations with Stein he never attempted to hype or sell his products. He respects the work of other top designers and I always feel his enthusiasm and his sincerity.”
David Caplan, Stereo Times
what our goal is
Sound without coloration
“The one company I can count on that stresses linearity as well as improved definition is SteinMusic of Germany.”
Robert H. Levi, Positive Feedback

hear for yourself
Sound is decided in the room, not on paper. In our listening room in Mülheim we take time for your system and your music. Or at a specialist dealer near you.
