Balanced AAVA volume control
As a first in an integrated amplifier, the Accuphase E-650 features the sophisticated Balanced AAVA type volume control incorporated in Accuphase’s top-of-the-line preamplifier model C-3850. Balanced AAVA uses two AAVA circuits driven in a fully balanced configuration. This completely cancels out any external noise and results in unsurpassed S/N ratio.

High-accuracy, high-rigidity volume sensor construction with massive yet responsive feel AAVA uses a volume control knob that looks similar to conventional controls. However, Accuphase also paid careful attention to volume sensor construction. The rotary mechanism is assembled with high accuracy and mounted to a highly rigid frame extruded from a single aluminum block. The solid brass shaft has a diameter of 8 mm and gives a pleasingly massive yet responsive operation feel to the volume knob. Floating suspension technology developed by Accuphase for its SA-CD/CD players is used to mount the volume sensor mechanism to the main chassis. Furthermore, utterly smooth and quiet operation is assured also when adjusting the volume with the remote commander, thanks to insulators that dampen any vibrations of the drive motor. Triple parallel push-pull output stage with power MOS-FETs and power amplifier stage mounted on a large heat sink. Two identical units are arranged on the left and right sides of the chassis. Class A operation (30 watts into 8 ohms). Guaranteed linear power of 120 watts into 2 ohms, 60 watts into 4 ohms, 30 watts into 8 ohms per channel. Strong power supply with massive high-efficiency toroidal transformer and large filtering capacitors. The Accuphase E-650 uses a massive power transformer with high output capability. Highly effective filtering is realized with two custom-made aluminum electrolytic capacitors, each with a large 50,000 μF rating.
