Audio journals have celebrated it for years as “the ultimate power amp”. This power amplifier represents the best in engineering ingenuity and available electronic components. With an extremely high damping factor and the ability to deliver huge currents the 909 effortlessly controls any speaker. Even speakers with very low impedance are no match for the unflappable power supply of the 909. Pulse transmission is practically load-independent. The warm and at the same time detailed sound signature of the 909 impresses even the most demanding audiophiles. Its ability to communicate even the smallest musical detail at any volume level with any speaker is unequalled on the world market today. Many awards bestowed on the 909 by international audio magazines have impressively confirmed this unique position.

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.
