Accuphase E-800S Class-A Precision Integrated Stereo Amplifier

Description

The E-800S is our flagship model that incorporates the full breadth of Accuphase's accumulated knowledge on integrated amplifiers. The preamplifier section incorporates a Balanced AAVA type volume control, while the power amp stage relies on an instrumentation amplifier principle and six-fold parallel push-pull configuration using power MOS-FETs driven in Class A, driving any loudspeakers to higher dimensions of sound. Enjoy the blissful acoustic space provided during playback with the E-800S.

Features

The Accuphase E-800S is an integrated amplifier with a fully balanced configuration from input to output, featuring a Balanced AAVA volume control and high-accuracy, high-rigidity volume sensor construction. Its power amplification stage is configured as an instrumentation amplifier and employs a six-fold parallel push-pull configuration using power MOS-FETs driven in Class A.

The E-800S delivers a linear power output of 50 watts into 8 ohms, 100 watts into 4 ohms, and 200 watts into 2 ohms, with a high damping factor of 1,000 for strong loudspeaker control. A strong power supply incorporates a massive high-efficiency toroidal transformer and large filtering capacitors, while MOS-FET switch-based protection circuitry provides reliable protection.

For connectivity, the amplifier includes three sets of balanced inputs and two expansion slots for option boards. It also features a dedicated high-quality headphone amplifier with discrete circuitry, a speaker output protection circuit to guard against short-circuiting, and high-carbon cast iron insulators for superior vibration damping.
