Like all Burmester devices, the 911 MK3 power amplifier is handcrafted in the Berlin factory. Selected components with the tightest tolerances are used to manufacture the Burmester power amplifiers. This step is crucial so that the product leaves nothing to be desired in terms of its technological content, unlimited reliable function and high value retention over many years. The aluminum heat sinks, which give the Burmester power amplifiers their characteristic design, are pressed by a Berlin supplier with a specially made tool. The majority of the other components are also manufactured in the immediate vicinity and at the highest level.
