Introduction

The Michi X3 Series 2 combines flagship-level power amplification with a reference-class digital section and vinyl-ready phono stage. Delivering up to 350 W into 4 Ω (200 W into 8 Ω) from its robust Class AB output stage and pristine 8-channel ESS SABRE DAC, it anchors any high-performance system with authority and finesse.

Design

Housed in a substantial aluminum chassis optimized for low resonance, the X3 Series 2 separates analogue, digital and power-amp circuits with individual toroidal transformers. Its industrial-grade construction and precision-machined faceplate ensure rock-steady operation and immunity to external vibration and noise.

Application

As an all-in-one centerpiece, the X3 Series 2 handles everything from streaming to vinyl. Connect analog sources via RCA or XLR, plug in a turntable to its moving-magnet phono input, or stream wirelessly over aptX HD Bluetooth. Its PC-USB input supports PCM up to 384 kHz and native DSD256 (plus MQA decoding), while coaxial and optical S/PDIF round out the digital I/O.

Technology Overview

• Class AB Power Stage: Custom-tuned amplifier module delivers high current with low distortion, remaining stable into 2 Ω speakers.
• 8-Channel ESS SABRE ES9028PRO DAC: Four channels per stereo path reduce noise floor and expand dynamic range.
• Discrete Phono Stage: Moving-magnet input with precision RIAA equalization and switchable loading for vinyl aficionados.
• Galvanic Isolation: Separate transformers and grounding schemes eliminate crosstalk between analog, digital, and power sections.
