The Dynamic performance is the key to musical behaviour. In Platinum the musical dynamics are maintained precisely by making sure that each amplification stage is fed by its own power supply. In that way the power rails for the preamplifier and driver circuits avoid modulation by, say, the current demands of the output stage. mplifier stages are normally linked by capacitors to take care of DC offsets. Unfortunately capacitors in the signal path degrade the purity of the music signal. In Platinum direct coupling of each stage is enabled by the use of a DC servo – a circuit that compensates for any unwanted DC voltage and removes it without affecting the music signal.
