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

The E-800S is Accuphase’s 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.
