Revolutionary AAVA volume control. A power amplifier section featuring high-power transistors in a parallel push-pull configuration, complemented by a robust power supply and low impedance output stage. 120 watts of quality power into 4 ohms, with a damping factor of 400. Current feedback amplifier topology assures excellent phase characteristics in the high range, and the instrumentation amplifier principle enables fully balanced signal paths. Power MOS-FET switches in the protection circuitry eliminate the need for mechanical contacts.

Pursuit of performance and sound quality results in capability well beyond its class, approaching the level of separate-type amplifiers.

Features:

  • Revolutionary AAVA volume control
  • Output stage with high-power transistors in a parallel push-pull arrangement delivers high-quality power: 90 watts x 2 into 8 ohms
  • The power amplifier stage features an instrumentation amplifier configuration for balanced signal transmission
  • Logic-control relays for the shortest signal paths
  • Strong power supply with a massive high-efficiency transformer and large filtering capacitors
  • The main IN button allows the separate use of the preamplifier and power amplifier sections
  • Numeric indication of volume level

Providing high-quality power, the E-270 can handle even the most difficult loads. With a huge power transformer and large filtering capacitors, this amp can deliver 120W/ch at 4 ohms and 90W x 2 at 8 ohms.

Using the AAVA volume control system found in higher models, the signal does not pass through any variable resistors, ensuring the best possible performance.

Providing the undeniable quality of Accuphase in a smaller chassis, the E-270 delivers clean, reliable power and exceptional performance.
