E-280 is a 90w at 8ohms Class AB 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 utilizes 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.
Pursuit of performance and sound quality results in capability well beyond its class, approaching the level of separate type amplifiers.
