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.
