Accuphase E-280 Integrated Amplifier

£5,100.00

The New Accuphase  E-280 is an integrated stereo amplifier equipped with "AAVA volume control" that achieves a high signal-to-noise ratio and low distortion ratio. The power amplifier section realizes high quality power of 120W / ch (4Ω) by parallel push-pull configuration of high power transistor and low impedance of powerful power supply section and output circuit. Furthermore, the current feedback amplifier circuit excellent in the phase characteristic of a high region is adopted, and the signal path is balanced transmission by an instrumentation amplifier. The damping factor that affects the behaviour of the speaker has been achieved to 500 by reviewing the pattern and wiring between the power amplifier and the speaker output terminal in order to reduce the output impedance. Achieves non-contact protection circuit with power MOSFET switch. Two new option boards can be added, achieving expandability equivalent to that of higher-end models. Pursuing the performance and sound quality of separate amplifiers to the utmost limit, we will open up a new stage that exceeds the class.
