From a purely technical standpoint, the challenge was to design a circuit that would be simple and yet uncompromising in terms of musicality and reliability. Using Surface Mounted with tight tolerance components associated with traditional ones at the most strategic places enabled to shorten the signal path length. The amplification uses the highly acclaimed Hitachi Lateral Mosfets 2SK1058 & 2SJ162 complementary power transistors, in a configuration of two pairs per channel. The input section uses a cascode differential stage for the best performance. Both the pre-driver and the driver stages are based on High-Voltage Power Bipolar Transistors used in HF designs. The driver operates in pure class A. The circuit is fully direct-coupled but for a single ingress capacitor. Each channel has its own power supply with a lefty 60,000 microfarads of filtration, achieved via high current diodes without switching peaks. A delayed start-up function linked to the D.C. protection circuit is built into each channel. The gigantic 1000 VA toroidal transformer has two separate windings for each channel. To avoid current saturation, a power resistor has been placed in the power supply. After a very short delay, this is coupled to a power relay that limits the current. The loudspeaker output terminals are fed by solid copper bars. The command receptor mounted on the faceplate works with the microprocessor, the switched power supply, the display, and six highquality Wolfson digital volume control circuits. A description of the Mimetism would not be complete should one omit the superb remote control.
