Accuphase E-280 Precision Integrated Stereo Amplifier

Revolutionary AAVA volume control. A power amplifier section featuring high power transistors in parallel push-pull configuration, complemented by a robust power supply and low impedance output stage. 120 watts of quality power into 4 ohms, with a damping factor of 400. Current feedback amplifier topology assures excellent phase characteristics in the high range, and instrumentation amplifier principle enables fully balanced signal paths. Power MOS-FET switches in the protection circuitry eliminate the need for mechanical contacts.
Pursuit of performance and sound quality results in capability well beyond its class, approaching the level of separate type amplifiers.
