The amplifiers produced by Accuphase have traditionally been known for their delicate and refined sound, and the E-5000 is no exception. In addition to this characteristic Japanese sound, the E-5000 also boasts impressive rhythmic qualities and dynamic performance.
The E-5000 is the flagship high-power Class AB integrated amplifier developed to mark Accuphase’s 50-year
anniversary. The preamplifier section features our superior Balanced AAVA volume control, while the power
amplifier section includes an instrumentation amp and power transistors in a five-fold push-pull arrangement
driven in Class AB. These circuits create a balanced circuit from input to output. With its precisely balanced circuits and solidly built output stage, the E-5000 integrated amplifier presents every piece of music in exquisite detail.
