Achieving absolute sound quality requires the creative interaction of cutting-edge technology, the use of only the finest electronic components and old-fashioned craftsmanship. Over 95 per cent of all processed parts and sub-assemblies derive from German manufacturers. Before assembly the components are carefully selected and only those conforming to tightly defined tolerances are ultimately processed. At the end of the manufacturing process each component is not only burned-in and thoroughly measured but also has to pass and extensive listening test before shipping. Approximately 300 computer-aided measurements are being taken before and after a seven-day burn-in period. A component advances to the final testing stage only if the measurements show no deviation. Finally, an associate manually tests every function and listens with well-trained ears to make sure that everything is up to Burmester standards.
