Accuphase E-650:

Innovative engineering and top-grade parts and materials come together in this product featuring the

 superb Balanced AAVA type volume control and a triple parallel arrangement of power MOS-FETs in

 the output stage. The power amplifier section employs the latest instrumentation amplifier configuration

 for balanced signal transmission, resulting in an integrated amplifier with fully balanced configuration

 from the inputs right through to the output. The massive power supply and low-impedance output

 circuitry deliver 150 watts per channel (into 1 ohm, with music signal) and a damping factor of 800.

First integrated amplifier featuring Balanced AAVA volume control.

Specifications :

Pure Class A operation(30 watts into 8 ohms)
