Accuphase E-305 Amplifier






The E-305V Integrated Amplifier is the cream of Accuphase's crop of state-of-the-art development technology. This new Integrated Amplifier was developed based on its predecessor, the E-305, but incorporates far more sophisticated features than those of the E-305.
As its name implies, an integrated amplifier combines two amplifiers, a preamplifier and a power amplifier, into a single chassis. Naturally, this makes operation easier and saves installation space.
However, it is very difficult for an integrated amplifier to achieve the electric characteristics on par with those of stand-alone amplifiers. The biggest reason for this difficulty is that the total gain of the integrated amplifier exceeds 100 dB, which can cause mutual interference and cross talk among internal units.
However, we, at Accuphase, have finally found a solution that satisfies even the severest audiophile demands. Drawing on our tradition of building separate-type amplifiers of world renown, we have used only the finest materials and applied innovative design to create this new Integrated Amplifier. Consequently, the E-305V has the quality of a stand-alone preamplifier and power amplifier in an integrated package.
Additionally, the power amplifier and the preamplifier of the E-305V can be used independently of each other if so set with a selector switch on the rear panel.
