Accuphase :: E-270 Integrated amplifier

E-270 represents a major overhaul of the E-260, reflecting latest design technology and featuring the same advanced AAVA volume control as the higher-ranked models E-600, E-470, and E-360.
AAVA is a revolutionary principle that redefines the concept of volume control from the ground up, operating purely in the analog domain for high performance and ultimate sound.
In the output stage, high-power audio grade transistors are arranged in a parallel push-pull configuration which significantly enhances the capability to safely drive low-impedance loads.
Output operation is sustained by the power supply with a massive power transformer and large filtering capacitors. This provides high-quality power output of 115 watts x 2 into 4 ohms or 90 watts x 2 into 8 ohms, along with a damping factor of 400, thanks to the redesigned circuitry.
