Our new monophonic power amplifier X-A220EVO 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 most “audiophile” design of our circuits allows us to achieve high level performance at a competitive price.
Construction: The steel frames have a flawless finish. The addition of methacrylate fronts enhances their successful aesthetics, while providing an important ergonomic dimension, thanks to an imposing vu-meter. The interior layout is rational and compartmentalized. 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, four 10,000 µF / 80 V capacitors smooth the DC current. A NE5532 operational amplifier is shown on the input board with a balanced/unbalanced switch. The power stages call for a triple push-pull of complementary NJW0281G / NJW0302G transistors, delivering up to 220 W / 8 ohms in class AB. The amplifier can operate in two modes accessible via a switch: when the High Bias function is engaged, the X-A220EVO operates in “class A” on the first few watts and then automatically slides into class AB.
