Product Description:
The X430 is a high-power, Class AB Integrated Amplifier built for demanding loudspeakers and real-world dynamics, delivering 340 watts per channel into 4 ohms (210 watts into 8 ohms). High-current output stages are paired with an exceptionally low-noise foundation, anchored by an in-house manufactured oversized custom toroidal transformer with optimized power and signal paths that minimize noise and distortion.
