Accuphase E-480 Integrated Amplifier

Accuphase



E-480 Integrated Amplifier

Preamplifier section features the latest implementation of AAVA volume control for further enhanced clarity. Instrumentation amplifier principle in power amplification stage allows fully balanced signal transmission and realizes top-notch S/N ratio. Balanced Remote Sensing enables low impedance of output circuitry, resulting in a damping factor of 600. Power amplification stage uses power MOS-FETs in triple parallel push-pull configuration, delivering 180 watts into 8 ohms for dynamic music enjoyment.

  • Revolutionary AAVA volume control
  • Power amplification stage with power MOS-FETs in triple parallel push-pull configuration
  • Rated output 180 watts into 8 ohms
  • Damping factor 600
  • Instrumentation amplifier principle in power amplification stage allows fully balanced signal transmission
  • MCS+ topology and current feedback in power amplification stage
  • Strong power supply with massive high-efficiency transformer and large filtering capacitors
