The Accuphase PS-520 features a differential push-pull arrangement of power MOS-FETs for the waveform compensation amplifier, which further improves the precision of the reference signal and thereby the sound quality and performance of the power supply.

All circuitry in the PS-520 is analog. The power source waveform containing noise and distortion is compared to a highly accurate and stable reference waveform. Since there are no oscillators or switches, the PS-520 itself does not act as a source of spurious high-frequency noise.
