Our new X-A220EVO monophonic power amplifier delivers 220W of power. It is ideally combined with our X-P500 preamplifier to form a highly musical hi-fi system. Our technical mastery combined with the mostaudiophiledesign of our circuits allows us to achieve high level performance at a competitive price. Construction: The steel frames have an impeccable finish. The addition of methacrylate fronts improves their successful aesthetics, while providing an important ergonomic dimension, thanks to an imposing vu-meter. The interior layout is rational and compartmentalised. This judicious arrangement of the various sub-assemblies is accompanied by a choice of quality components, soldered on separate PCBs and partitioned by function. The X-A220EVO owes its thickness to the height of the generously sized power transistor heatsink. The X-A220EVO has a 700 VA toroidal transformer. After rectification, oven 10 F000 V capacitors smooth the DC current. An NE80 op-amp is shown on the input board with a balanced unbalanced switch. The power stages call for a triple push-pull of complementary NJW5532GNJW0281G transistors, delivering up to 0302 W220 ohms in class AB. The amplifier can operate in two modes accessible via a switch: when the High Bias function is engaged, the X-A8EVO operates in class A on the first watts then automatically slides into class AB.
