Building on the renowned E-650, this latest Class A amplifier delivers an even richer and more immersive listening experience. With its exquisite design enhancements, including a refined gold trim and robust controls, the E-700 is not just an amplifier, but a piece of art. Its ability to drive large, demanding speakers with ease, combined with the remarkable low noise floor and dynamic range, ensures every note is delivered with pristine clarity and depth. Whether you're filling a large room or creating an intimate soundscape, the E-700 excels, providing unparalleled power and detail that will satisfy even the most critical ears. Discover a new level of audio excellence with the Accuphase E-700, where superior engineering meets aesthetic perfection.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cp\u003eThe E-700 has a Pure Class A operation (35 watts into 8 ohms). Guaranteed linear power: 120 watts into 2 ohms, 60 watts into 4 ohms, 30 watts into 8 ohms; and the preamplifier and power amplifier sections can be used separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBalanced AAVA volume control\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOne of the key features of the E-700 is its Dual Balanced AAVA volume control system. AAVA stands for \"Accuphase Analog Vari-gain Amplifier,\" which is a proprietary technology that provides precise and accurate volume control with minimal noise and distortion. The Dual Balanced AAVA system uses two separate AAVA circuits for left and right channels, which helps to maintain perfect channel balance and stereo imaging.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOutput stage with power MOS-FETs in triple parallel push-pull configuration\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTriple parallel push-pull output stage with power MOS-FETs and power amplifier stage mounted on a large heat sink.
