Michi X430 Integrated Amplifier
Powerful Class AB Performance with High-Resolution Digital Connectivity
The Michi X430 is a high-performance integrated amplifier combining powerful Class AB amplification, advanced digital connectivity, and refined analog circuitry in a single premium component. Delivering 340 watts per channel into 4 ohms and 210 watts per channel into 8 ohms, the X430 uses custom-tuned push-pull high-current output transistors to provide exceptional dynamics, control, and transparency with demanding loudspeakers. At the heart of the X430 is an ESS SABRE ES9039Q2M 32-bit DAC, supporting high-resolution digital playback through three coaxial, three optical, and PC-USB inputs. PC-USB supports PCM up to 32-bit/384kHz and DSD256, while Bluetooth provides wireless streaming with aptX HD and AAC support. HDMI ARC enables convenient connection to a compatible TV for a seamless 2.1-channel system. The X430 also features a Moving Magnet phono input, three RCA line-level inputs, a balanced XLR input, dual subwoofer outputs, and two sets of user-selectable A/B speaker terminals. Its large, customizable full-color display can show spectrum analyzer and VU meter views, while the precision-machined aluminum construction, glass front panel, and knurled volume control reflect Michi's premium design philosophy.
