About the E-550

The Accuphase E-550 is the ultimate integrated pure Class A amplifier, utilizing power MOS-FETs arranged in a triple parallel push-pull configuration driven in pure Class A operation. It incorporates innovative AAVA (Accuphase Analog Vari-gain Amplifier) volume control for superior sound quality without variable resistors, current feedback principle and MCS+ topology in the power amplifier section for excellent high-frequency phase characteristics, and logic-controlled relays for straight signal paths. The sturdy power supply includes a large 430 VA toroidal transformer and high-capacity filtering capacitors (10,000 µF × 8). Features include balanced inputs, tone controls, loudness compensation, option board slots for expansion (e.g., phono, DAC), EXT PRE for separate pre/power use, and dual speaker terminals accepting Y-lugs or banana plugs. Analog peak power meters and remote control (RC-200) are provided.
