Accuphase E-480 Integrated Amplifier


The E-480 is equipped with the latest “AAVA” method volume control in the preamplifier part, making it possible to adjust the volume fresher. The power amplifier part which is fully balanced transmitted by the instrumentation amplifier configuration achieves a high SN ratio. Furthermore, due to the low impedance of the output circuit by “balanced remote sensing”, the damping factor: 600 was achieved. “Power MOSFET” Enjoy a powerful sound of 180 W / 8 Ω by 3 parallel push-pull power amplification stages.
