Advance Paris X-A220EVO

The new X-A220EVO monaural power amplifier delivers 220W of power. It is ideally combined with the X-P500 preamplifier to form a highly musical hi-fi system. The technical mastery combined with the most “audiophile” circuit design allows them to achieve high-level performance at a competitive price.

Construction: The steel frames have an impeccable finish. The addition of methacrylate front panels 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 direct current. An NE5532 operational amplifier is indicated 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 Ω 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 watts then automatically slides into class AB.
