Denon POA-1003

POA-1003 Power Amplifier was introduced to do away wit unnecessary decoration with the sole object of listening to music. Simple in design, with no distortion, it offers quick responding transparent sound by providing circuitry for DC amplifiers. Left and right completely monaural constitution. Either side is provided with an excessive power circuit, highly accurate peak meter allowing ultra wide, and low distortion.

DC power amplifier with features of cascode coupling at  the first stage low noise FET differential amplifier, a stage of current mirror differential amplifier with emitter follower predriver, bipolar type power transistor of a clas with a collector loss of 100W in a novel circuitry of pure complementary ICL OCL, producing a wide band, low distortion, and high Signal-to-Noise ratio.

A stable DC drift of 1,6 mV/°C

Exceptional damping factor of 200

Highly stabilized constant voltage circuitry use in the first stage power section, oversized capacitor 88,000 µF, left and right independent transformer.
