Accuphase E-380 Integrated Stereo Amplifier
The E-380 realizes a 20% increase in rated output power thanks to a reinforced power amplification stage and power supply. The further evolved AAVA volume control system allows music enjoyment at any level without even the slightest degradation of signal quality. The power amplifier section utilizes the instrumentation amplifier principle to achieve outstanding S/N ratio. Low impedance design of the output circuitry results in a damping factor of 500, ensuring that the potential of every speaker can be brought out to the fullest. Enjoy a musical performance of amazing transparency and dynamism.
