E270 VUE ARRIERE

100W/ch INTEGRATED STEREO AMPLIFIERE-370

Inheriting outstanding technology from the top-of-the-line E-600 and the high-power version E-470, the E-370 represents a full model change from the E-360.
At the heart of the preamplifier section is the same version of the AAVA volume control as found in the E-600, pushing the noise floor to an absolute minimum. The power amplifier block employs the latest instrumentation amplifier topology, enabling fully balanced signal transmission in all stages. This reliably shuts out external noise interference and ensures perfectly stable operation. As a result, overall S/N ratio has been improved by 3 dB.
Other impressive features include MOS-FET switches in place of relays for speaker protection, helping to ensure superb electrical characteristics and improve long-term reliability. The circuit topology of the output stage is designed for extremely low impedance, resulting in a damping factor of over 400, demonstrating excellent speaker drive capability.

E370 VUE ARRIERE

180W/ch INTEGRATED STEREO AMPLIFIERE-470

Inheriting outstanding technology from Accuphase's 40th anniversary commemorative models, the E-470 represents a full model change from the E-460. Internally, the preamplifier and power amplifier sections are kept entirely separate, in order to allow each to develop their full potential, rivalling the performance and sonic excellence of separate type components. With a simple flick of a switch, the POWER IN feature allows individual use of the two sections. At the heart of the preamplifier section is a further evolved AAVA type volume control, and the power amplifier block is configured with the latest instrumentation amplifier topology, enabling fully balanced signal transmission throughout. The MCS+ approach improves crucial performance parameters by employing multiple identical circuits in parallel, and current feedback provides optimum stability. As a result, the low impedance output stage achieves a damping factor of 500. MOS-FET switches are used in place of relays for speaker protection, helping to ensure superb electrical characteristics and improve long-term reliability. Power MOS-FET devices arranged in triple parallel push-pull pairs for each channel greatly enhance the ability of the amplifier to drive low-impedance loads.
