...substantial "open-loop" distortion. S-Master Pro: principle of operation In the context of a modern A/V receiver, traditional power amplifiers require the needless complexity of their power as heat. Changes in the audio signal cause immediate changes in transistor performance! The normal solution is ... processed through a digital preamplifier-only to be converted to analog prior to the input. Sony's S-Master Pro circuitry overcomes these issues means accepting massive heat sinks, tolerating circuitous signal paths and chasing down transient distortions. Why Digital Amplification?
