The new Accuphase E-280 employs the latest AAVA volume control system and attains 12% lower noise performance. And the power module section which adopts the contactless MOS-FET switches represent a damping factor of 500. 2 options boards can be added for improved expandability, from the analog records to the Hi-res digital sources, E-280 allows audiophiles to give a direct access to every music source. The evolved E-280 is irreplaceable to all music lovers with its magnificent technology philosophy of higher-grade models.

Integrated Amplifier with Scalability that Exceeds the Imagination

The AAVA volume control builds upon the knowledge of high end equipment to control volume without loss of information. The power amplification section utilises the instrumentation amplifier principle to create an ideal speaker driver. The low impedance design of the output circuitry brings out the full potential of every speaker. Two option boards can be added for improved expandability. The E-280 sound performance will defy the imagination.

AAVA volume control – AAVA is a revolutionary type of volume control that completely does away with any variable resistors in the signal path, instead using a combination of 16 V-I converter circuits with different gain. Unlike conventional volume controls, the music signal is not attenuated by a rotary resistor, so that low distortion and an optimum S/N ratio can be maintained over the entire volume range. The E-280 utilises maximum gain in 4 parallel rows and secondary V-I converter circuits arranged in 2 parallel rows, which doubles the total output current capability and halves the circuit impedance to further reduce noise.

Reinforced power amplification stage – A power amplification stage with two bipolar transistors in a double parallel pull-push configuration for the left and right channels mounted directly to large heat sinks. Rated output of 90watts  into 8 ohms or 120watts into 4 ohms of high power.

25% improved damping factor – Balanced Remote Sensing and MOS-FET switches result in a damping factor of 500, representing a 25% improvement over the predecessor model.

Power supply circuitry designed for optimum stability – The large transformer and massive 30,000 μF filtering capacitors provide rock-stable high quality power.
