Of course, like all Burmester products for high-end home audio the 956 MK2 power amplifier is also hand-assembled in the Berlin factory and is subject to the same strict quality control procedures. Up to 300 computer-aided measurements are taken before and after a one-week burn-in period. The protocols of these tests are saved and may later be used, if necessary, to return a damaged unit to its original state. They also serve as reference for future upgrades to incorporate technological advances.
