The X-A220 EVO is the kind of mono power block that makes you reconsider what well-engineered solid-state can accomplish before it gets expensive — genuinely muscular output with a High Bias switch that nudges the first watt into Class A territory, where the fine grain of tone actually lives. The NJW complementary push-pull output stage and a substantial toroidal transformer give bass lines real physical authority, and transients arrive with an edge that reminds you music has shape, not just warmth. Run a pair in mono configuration behind a capable preamp and the soundstage opens into real geography — instruments hold their own coordinates rather than pooling together. The analog VU meters track the music with a satisfying physicality, making you aware, moment to moment, that serious power is happening.

- Liner Notes
Our new X-A220EVO monophonic power amplifier delivers 220W of power (at 8 ohms). A pair of X-A220 Evo combined with our X-P700 pre-amplifier forms a highly musical Hi-Fi system at an exceptional value. Engineering expertise in the design of our circuits allows us to achieve high level performance at a competitive price.
Construction: The steel frames provide a stable foundation. The addition of a methacrylate front panel results in a beautiful looking design showcasing the prominent Vu Meter. The interior layout is strategic and compartmentalized. This judicious arrangement of the various sub-assemblies and choice of quality components, soldered on separate PCBs and partitioned by function provide the basis for excellent sound quality. The X-A220EVO's substantial height follows the requirement of the generously sized power transistor heatsink.
The X-A220EVO has a 700 VA toroidal transformer. After rectification, filter capacitors smooth the direct current. The power stages call for a triple push-pull of complementary NJW80G / NJW0281G transistors, delivering up to 220W (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 Watt then automatically slides to class AB.
