Dolf Koch developed Koch amps in 1988. He runs an amplifier company that is dedicated to creating an amplifier that is perfectly tonally balanced. Amps are built with tube chassis. They also have a custom shop that can make modifications on a special request. Everything that goes into the amplifier is carefully constructed. For more information, visit Koch's website or contact the company directly.
Amplifiers currently produced in Amersfoort, The Netherlands, since 1988. Koch amplifiers are distributed in the U.S. and Canada by StageTrix Products. Previously distributed by Audionova Inc. in Dorval, Québec, Canad and Eden Electronics in Montrose, MN.
