Fosi Audio ZD3 + Dual V3 Mono Fully Balanced System inc DAC & Amplifiers

Fosi Audio Balanced ZD3 DAC And Dual V3 Monoblock Hifi Amplifiers

Overview

The Fosi Audio ZD3 + V3 Mono System represents the next level of compact hi-fi performance — a fully balanced desktop or living-room setup that delivers effortless clarity and power. Designed for listeners who want true high-fidelity sound without the clutter, this three-piece system blends digital precision with dual-mono authority, combining the ZD3 DAC & Pre-Amp with two V3 Mono Class-D Power Amplifiers.

At the heart of the system and ZD3 lies the ESS ES9039Q2M chipset DAC, handling conversion with exceptional speed, accuracy, and tonal neutrality. Its advanced architecture preserves micro-detail and dynamics, while the USB interface supports high-resolution playback up to 768 kHz PCM and DSD512. The ZD3 DAC also includes HDMI ARC, optical, coaxial, and Bluetooth 5.0 with aptX HD — allowing seamless integration with computers, streamers, or smart TVs. Balanced XLR and RCA outputs maintain a clean, noise-free signal path to the amplifiers.

The V3 Mono amplifiers transform that precision into real power. Each compact block employs the acclaimed TPA3255 Class-D chipset, optimised for wide bandwidth and ultra-low distortion. Powered by dedicated 48 V supplies, the pair delivers 240 watts per channel into 4 Ω, providing exceptional control over demanding speakers. The sound is open and articulate, combining deep, controlled bass with smooth midrange texture and an extended, airy treble.

Every component reflects Fosi Audio’s minimalist approach to design. The CNC-machined aluminium housings are compact yet robust, ensuring excellent heat dissipation and silent operation. Internally, Japanese NCC, ELNA and German WIMA capacitors preserve tonal accuracy and long-term reliability. Together, the ZD3 DAC and dual V3 Mono amplifiers form a balanced system that rivals full-size separates, offering high-end sound from an elegantly simple and affordable setup.

For Groove Central listeners, this system captures the essence of modern hi-fi — refined, powerful, and beautifully understated. It’s music reproduced with clarity, scale, and emotion — sound that simply feels right.
