With a comprehensive range of inputs—including USB, HDMI ARC, optical, coaxial, and Bluetooth 5.0—and outputs like balanced XLR and single-ended RCA, the ZD3 integrates seamlessly into various home audio setups, from desktop systems to full home theater configurations. Its sleek design, intuitive controls, and robust feature set make it an ideal choice for audiophiles seeking high performance without complexity. Whether you’re streaming lossless music, connecting to a TV, or building a high-fidelity audio chain, the ZD3 elevates your listening experience with clarity and versatility.
High-Performance Audio Processing
At the core of the Fosi Audio ZD3 is the ESS Sabre ES9039Q2M DAC chip, paired with an XMOS XU316 USB interface for precise digital signal processing. This combination supports ultra-high-resolution audio, including PCM up to 32-bit/768kHz and native DSD512 via USB, delivering unparalleled clarity and dynamic range. The ZD3 achieves a signal-to-noise ratio (SNR) of ≥126dB and an exceptionally low total harmonic distortion plus noise (THD+N) of <0.00008%, ensuring near-perfect sound reproduction with minimal noise or distortion. Its dynamic range of ≥123dB and noise floor of ≤2μV allow subtle musical details to shine through, making it ideal for high-resolution audio files and critical listening. The fully balanced circuit design further reduces interference and crosstalk, providing a clean, immersive soundstage that rivals more expensive DACs. Whether you’re listening to classical music or modern recordings, the ZD3 faithfully reproduces every nuance with stunning accuracy.
Versatile Connectivity Options
The ZD3 offers a wide array of connectivity options to accommodate modern and traditional audio sources. Inputs include USB-B for direct computer connections, HDMI ARC for TV integration (supporting PCM up to 24-bit/192kHz, but not Dolby or DTS), optical and coaxial for CD players or other digital devices, and Bluetooth 5.0 with support for SBC, AAC, aptX, and aptX HD codecs for high-quality wireless streaming. Outputs feature balanced XLR for professional-grade equipment and RCA for standard amplifiers or powered speakers, with output levels of 5Vrms and 2.5Vrms, respectively. The inclusion of 12V trigger in/out allows synchronized power control with compatible devices like the Fosi Audio ZA3 amplifier, streamlining your audio setup. This versatility makes the ZD3 a central hub for diverse audio systems, from minimalist desktop rigs to complex home theater configurations, ensuring compatibility with devices like PCs, TVs, and streaming players.
Customizable Audio Experience
The Fosi Audio ZD3 stands out with its swappable DIP8 dual op-amp design, allowing users to tailor the sound signature to their preferences. It comes equipped with three LME49720 op-amps (two for XLR, one for RCA), but users can replace them with compatible options like NE5532, MUSES02, or SS3602 to achieve warmer, brighter, or neutral tonal characteristics. This feature caters to audiophiles who enjoy experimenting with their audio setup to match specific genres or headphones. Additionally, the preamp bypass mode enables the ZD3 to function purely as a DAC, delivering an unaltered signal for purists or those integrating it with external preamplifiers. The 1.5-inch OLED display provides clear, real-time feedback on input selection, volume, and sampling rates, while the included infrared remote simplifies operation from a distance, enhancing user convenience without compromising performance.
User-Friendly Design and Controls
Designed for ease of use, the ZD3 features a prominent orange knob for volume and menu navigation, complemented by a 1.5-inch OLED display that clearly shows input modes, sampling rates, and volume levels. The infrared remote control allows effortless adjustments from across the room, including input switching and volume control, with HDMI ARC mode supporting TV remote volume adjustments via CEC (note: eARC is not supported). The 12V trigger in/out ensures seamless integration with other audio components, automatically powering on or off connected devices for a cohesive system experience. A bypass switch allows users to toggle between preamp and pure DAC modes, catering to different use cases. The ZD3’s plug-and-play functionality supports Windows 7/8/8.1/10/11 (driver may be required for some versions), Mac OS X, and Linux without additional software, making setup straightforward for all users.
Robust Build and Aesthetic Appeal
The Fosi Audio ZD3 is housed in a compact, CNC-machined aluminum alloy chassis measuring 6.1 x 7.24 x 2.01 inches and weighing 2.65 pounds, offering durability and a premium aesthetic that complements modern audio setups. Its sleek black finish and minimalist design align with the Fosi Audio ZA3 amplifier, creating a visually cohesive stack for home audio systems.
