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.
