New schematics

Our new X-A220EVO monophonic power amplifier delivers 220W (at 8 ohms).

A pair of X-A220 Evo units combined with the X-P700 preamplifier form an extremely musical Hi-Fi system.

most audiophile design

Our technical expertise combined with the most "audiophile" design of our circuits enables us to achieve top-level performance at a competitive price.

successful aesthetics

Construction: The steel frames are impeccably finished. The addition of methacrylate fronts enhances their successful aesthetics, while adding 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.

delivers the most demanding dynamics

The X-A220EVO owes its thickness to the height of its generously dimensioned power transistor heatsink.

The X-A220EVO features a 700 VA toroidal transformer. After rectification, four 10,000 µF / 80 V capacitors smooth the DC current. The power stages call for a triple push-pull of complementary NJW0281G / NJW0302G transistors, delivering up to 220W (8 ohms) in class AB.

High Bias function is engaged

The amplifier can operate in two modes, accessed via a switch: when the High Bias function is engaged, the X-A220EVO operates in "class A" on the first Watt, then automatically switches to class AB.
