Accuphase E-560

The integrated amplifiers from Accuphase operating in full class A enjoy an excellent reputation both in Japan and overseas for their outstanding musical qualities. The E-560 represents a model change from the popular E-550. While incorporating the sophisticated technological know-how gained by Accuphase over the years, it features a further refined AAVA volume control and uses the latest circuit topology and strictly selected parts of the utmost quality. The E-560 is destined to become the new reference model for high-class integrated amplifiers.

As noble and weighty the E-560 is entering the stage as modestly does it specify its sheer
power, namely 30 watts per channel. According to our lab report however this figure can
be considered a nice understatement. Like its predecessor E-550, this 24-kg beauty can
indeed be counted among the “weaker” representatives of its price class, in spite of the
huge energetic capabilities of the power supply. It’s because a large amount of this energy
is blown in order to keep the transistors under full steam by means of high bias currents. In
fact, more than half of it is blown through the heat sinks and hence the usable power
reduced. But the wasted heat (perhaps not quite “ecologically correct”) generated by the
so-called Class-A circuitry is otherwise taking care that cross-over distortions are definitely
avoided during push-pull operation. In pairwise push-pull one transistor is responsible for
the positive and its team-mate for the negative half-wave of the signal. At the cross-over
point, transistors working in the energy-saving, low-bias Class-B mode are subject to
certain distortions which would yield a rather harsh, uneasy sonic picture.

As opposed to its predecessor, the E-560 is equipped with an even more powerful
gigantic toroidal transformer plus an additional current-feedback circuitry in the power
stage, which is typical for Accuphase. The latter is taking care of a fully balanced signal
processing in the power range. This trick is said to provide a completely distortion-free
signal and – nomen est omen – an absolute accuracy in phase up to the highest
frequencies.
