Accuphase A-80

Class A Stereo Power Amplifier

The A-80 is a stereo version of the 50th anniversary model A-300, and is a pure Class A stereo power amplifier that pursues reduced output impedance and constant voltage drive to bring out the full potential of the speakers. It is a flagship model. The power amplification stage uses 10 parallel push-pull class A operation using power MOSFETs, achieving linear high power outputs of 65W/8Ω, 130W/4Ω, 260W/2Ω, and 520W/1Ω. In addition, noise performance has been improved by using an ``instrumentation amplifier'' whose signal input section is composed of a balanced circuit, ``ideal gain distribution'' between the signal input section and power amplification section, and ``MCS+'' which is a two-parallel circuit. has been raised to the maximum. Additionally, a damping factor of 1,000 has been achieved by reducing output impedance through balanced remote sensing and semiconductor switches. In addition, it is equipped with a protection circuit that prevents short-circuit accidents of the speaker terminals, so you can use it with confidence.

Please appreciate the alluring sound of A-80 which will be an object of aspiration for the audiophiles.
