The digital and analogue control centre of the new Series 4xx
Michi P430 is a stereo preamplifier with ESS Sabre DAC, MM phono stage, HDMI eARC and comprehensive connectivity, designed to drive a higher-level separate system.
It is the command source of the Michi Series 4xx: it selects and processes digital music, vinyl and analogue signals before handing them to a power amplifier. The black aluminium chassis, TFT display and dual-mono construction share their language and dimensions with the S430 power amplifier, its natural partner in a separate stereo system.
Key features
- 32-bit ESS Sabre ES9028PRO DAC
- Dual toroidal transformers and dual-mono circuitry
- MM phono input, four RCA and one XLR analogue inputs
- 32-bit/384 kHz USB with DSD and DoP, Roon certification and HDMI eARC
- Two XLR outputs, RCA pre-out and two subwoofer outputs
A preamplifier, not an integrated amplifier
P430 does not power loudspeakers directly: it organises sources, controls volume and sends a low-noise signal to an external power amplifier. This separation lets the power supply and circuits focus on signal control, leaving the power stage with the sole task of driving loudspeakers.
High-resolution digital
The ESS Sabre ES9028PRO converter handles the digital section, with a rear USB input up to 32-bit/384 kHz, DSD and DoP. Six S/PDIF inputs, three optical and three coaxial, welcome players, streamers and TV; HDMI eARC makes P430 a stereo listening hub for television too.
Vinyl, analogue sources and Bluetooth
The MM phono stage allows direct connection of a moving-magnet turntable. Four RCA sockets and an XLR input sit alongside Bluetooth with aptX HD and AAC: a provision that keeps analogue and digital paths separate, without giving up everyday sources.
Power supply and dual-mono architecture
Two toroidal transformers and dual-mono circuitry help keep the left and right channels separate. The result is a preamplifier designed to preserve microdynamics, soundstage and signal stability, with a technical approach consistent with Michi's more ambitious construction.
The S430 partner
P430 and S430 have the same 431 mm chassis, black finish and customisable TFT display, yet perform distinct roles. P430 prepares and distributes the signal; Michi S430 amplifies it to 230 W RMS per channel into 8 ohms. Connected via XLR, they form a tidy, complete separate stereo system.
Control and integration
A high-resolution TFT display, tone controls, 12 V trigger, Ethernet and RS-232 make integration into an advanced system straightforward. RCA pre-out, two XLR outputs and two subwoofer outputs allow the choice of power amplifier and completion with one or two active subwoofers.
