E-370

About the E-370

The Accuphase E-370 is a high-performance integrated stereo amplifier delivering 100 watts per channel into 8 ohms, with 150 watts into 4 ohms. It inherits advanced technology from the flagship E-600 and the high-power E-470 models, representing a full model change from the E-360. Central to its design is the revolutionary AAVA (Accuphase Analog Vari-gain Amplifier) volume control, which eliminates the use of variable resistors in the signal path, thereby minimizing noise and distortion and maintaining superb sound quality at any volume level. The power amplifier section employs the latest instrumentation amplifier topology for fully balanced signal transmission, which effectively blocks external noise and ensures stable operation, improving the overall signal-to-noise ratio by 3 dB. The output stage uses bipolar transistors in a parallel push-pull configuration for excellent performance with low-impedance loads, resulting in a damping factor over 400 for superior speaker control. Speaker protection is handled by MOS-FET switches instead of relays, enhancing electrical characteristics and long-term reliability. The E-370 also features a high-gain phono equalizer supporting both MC and MM cartridges, multiple line-level and balanced inputs, two option board slots for digital or analog disc input boards, a dedicated headphone amplifier with speaker output off function, and separate preamplifier outputs and power amplifier inputs for flexible system integration. The amplifier weighs approximately 23 kg and measures 465 mm x 171 mm x 422 mm (WxHxD).
