The imposing appearance of the 909 MK5 power amplifier gives form to the underlying total commitment to the highest level of audio reproduction. The massive heat sinks with their silver anodized fins are an easily recognizable feature of Burmester power amps. The same is true for their ability to project the finest sound at any volume level without strain or distortion. Form and function of the 909 meld to a commanding entity, which serves as reference point for all other power amps in Burmester’s portfolio, not to mention the rest of the industry.
To complete a 909 power amplifier requires a whole range of assembly and quality control stages in the Berlin factory. From hand-assembled circuit boards, where each soldered connection is carefully checked, and top-quality transformers to computer-aided measuring stations it takes about 100 hours to produce a 909. This is not counting the seven-day burn-in period and the final quality control and listening tests under real-world conditions. All this is necessary to ensure that the customer receives an audio component that is outstanding in every respect.
