Description

The Fosi Audio ZH3 is a complete Hi-Fi solution that unifies a DAC, headphone amplifier, and preamp into one precision-engineered device, delivering studio-grade clarity for any desktop setup. Powered by the AKM 4493SEQ DAC, XMOS XU316 USB processor, and four TI OPA1612 op-amps, it offers rich detail, ultra-low noise, and lifelike accuracy. With support for PCM 32-bit/768 kHz, DSD512, and 24-bit/192 kHz optical/coaxial inputs, the ZH3 ensures true lossless playback across modern and legacy sources. Its powerful output—up to 2570 mW × 2 balanced with three-stage gain control—makes it suitable for everything from sensitive IEMs to demanding planar magnetic headphones.

Equipped with USB-C, optical, coaxial, RCA, 4.4 mm balanced, 6.35 mm single-ended, and XLR/RCA preamp outputs, the ZH3 becomes the central hub for any audiophile, studio, or workstation setup. Six digital filters, bass/treble EQ, Bypass mode, and swappable op-amps allow personalized sound tuning, while the high-contrast LCD maintains a modern, clean interface. Finished in a CNC-machined aluminum chassis and bundled with essential accessories, the ZH3 delivers exceptional performance, flexibility, and refined design in one compact desktop package.

ALL-IN-ONE HI-FI SOLUTION — DAC, AMP & PREAMP IN ONE BODY

The ZH3 integrates three essential audio components into a single precision-engineered device. Acting simultaneously as a high-fidelity DAC, headphone amplifier, and preamp, it brings professional-grade sound processing to your desktop setup. Whether driving high-impedance headphones, feeding active studio monitors, or serving as a source for a Hi-Fi system, the ZH3 delivers absolute sonic precision and convenience, ensuring your music is always heard in studio-grade clarity.

PREMIUM AUDIOPHILE ARCHITECTURE — BUILT AROUND FLAGSHIP COMPONENTS

Inside the ZH3 beats a pure audiophile heart. The DAC section is powered by the AKM 4493SEQ, renowned for its silky tonality and low distortion, while the XMOS XU316 USB audio processor ensures bit-perfect decoding for both PCM and DSD formats. Four Texas Instruments OPA1612 op-amps drive the analog stage, achieving ultra-low noise and high dynamic range, so every instrument and vocal nuance is preserved. Ideal for audiophiles, studio engineers, and discerning listeners who demand lifelike sound accuracy.

ULTRA-HIGH RESOLUTION AUDIO SUPPORT — TRUE LOSSLESS PLAYBACK

Experience uncompromised fidelity and texture. The ZH3 decodes PCM up to 32-bit / 768 kHz and DSD512 via USB, reproducing music with depth, warmth, and spatial accuracy. For legacy sources, optical and coaxial inputs support up to 24-bit / 192 kHz, ensuring full compatibility across modern and vintage digital systems. Whether you’re streaming hi-res files, playing FLACs, or listening to studio masters, the ZH3 renders every tone with reference-level precision — just as the artist intended.

IMMENSE DRIVING POWER WITH THREE-STAGE GAIN CONTROL

Built to handle everything from delicate IEMs to power-hungry planar magnetics, the ZH3 delivers up to 2570 mW × 2 @ 32 Ω (balanced) and 640 mW × 2 @ 32 Ω (single-ended). Its three-level gain switch allows precise tuning for headphone impedances from 16 Ω to 300 Ω, ensuring noise-free, distortion-free, and dynamic performance at any volume. Whether mixing in the studio, gaming competitively, or relaxing with jazz, the ZH3 adapts effortlessly — providing optimal power and sonic balance for every scenario.

VERSATILE INPUT & OUTPUT CONNECTIVITY

With its rich I/O selection, the ZH3 becomes the central hub of any Hi-Fi or workstation setup. It offers USB-C, optical, coaxial, and RCA inputs for flexible digital connectivity from PCs, streamers, or gaming consoles.
