Description
Accuphase E-800S Class A Integrated Amplifier
Flagship Class A Performance
The Accuphase E-800S is the flagship model of the brand’s renowned integrated amplifier lineup. Engineered as the culmination of decades of analog design excellence, it incorporates a fully balanced signal path from input to output, delivering impeccable clarity and tonal depth. The power stage features a six-fold parallel push-pull MOS-FET configuration operating in pure Class A, resulting in smooth, distortion-free output even under demanding loads. With up to 200W into 2 ohms and a damping factor of 1,000, the E-800S drives even the most complex speaker systems with authority and finesse.
Precision Preamplifier Stage
At the core of the E-800S is Accuphase’s revolutionary Balanced AAVA volume control, offering exceptionally accurate signal handling without any channel imbalance or degradation in sound quality. The preamp also includes a high-rigidity volume sensor and instrumentation amplifier topology to ensure optimal signal integrity. With three sets of balanced inputs, the E-800S easily accommodates high-end source components and maintains a pure signal path from source to speaker.
Engineering Excellence and Expandability
Internally, the E-800S boasts a massive high-efficiency toroidal transformer, large filtering capacitors, and a robust MOS-FET switching-based protection circuit to ensure stable, reliable performance. Two rear-panel expansion slots offer support for optional DAC or phono modules, while a dedicated, discrete headphone amplifier makes private listening an uncompromising experience. Housed in a rigid chassis with high-carbon cast iron insulators, the E-800S achieves class-leading vibration control and mechanical stability.
