Every single Burmester machines is carefully selected and built to withstand any rigorous task thrown in their way. Comprehensive stress tests are conducted on every Burmester machine, a stamp of approval is never given just because the machine can power on normally. Extreme or even impossible scenarios are thrown at these machines to see how it can withstand these kinds of conditions. For example, in terms of power amplification, under normal condition it is consider excellent if the machine can maintain linearity under 2 ohms speaker loads. But that’s not enough to pass Burmester’s stress test, where they will stress test the equipment in under 1 ohm or 0.5 ohm loads. Even then, it is expected for the power amplifier to remain linearity after hours of constant load. Only then Burmester will certify its power amplifiers as worthy of its name. You may ask how Burmester can achieve this kind of performance. The answer lies in the ultra high specs of parts they use. Burmester always knew that only when you carefully match high quality parts that are perfectly compatible that would allow you to achieve that maximum efficiency. This is why the Burmester 911 power amplifier has had one of the highest damping factors of all amplifiers manufactured worldwide for the past 20 years.

 

Some may question whether or not if this kind of rigorous testing is necessary, and the simple answer might be no. There might never have been a scenario during normal use that will ever allow the machine to reach such extreme conditions. Like driving a supercar, even though you may never reach the maximum speed of 350km/h, it is reassuring to know that it is perfectly capable of achieving such a level if it is ever necessary. It is a sense of confidence in its capabilities and ambition in testing new limits. It represents the spirit of every audiophile – uncompromising design, and the pursuit of the highest fidelity of sound.
