E-280 Integrated Amplifier

Description

E-280

The E-280 stereo amplifier boasts an output of 90 W into 8 ohms as the result of superior craftsmanship in development and refined technologies. The pre-amplifier is equipped with the advanced AAVA volume control to allow for volume adjustments that maintain the same amount of information. The power amplifier section is configured using the Instrumentation Amplifier principle with balanced circuits that provide superb noise performance and contains a power amplification stage in the large heat sink with bipolar transistors in a double parallel push-pull configuration. Combined with the Balanced Remote Sensing and MOS-FET switches, the E-280 achieves a damping factor of 500, a 25% improvement over previous models. Two option board slots allow for simultaneous use of both digital and analog disc input boards. Musical performances on the E-280 are delivered at a scale beyond the imagination.
