Proprietary VitOS System

Octa-Core Processor

OCXO Precision Clock

Comprehensive Digital Outputs

Dual NVMe SSD Architecture

Physically Isolated Dual LAN

Dual-Mode Grounding System

Native Roon Server

Multi-Device Concurrent Operation

Powerful Processing Core

Powered by a high-performance 7nm CPU with 8 cores and 12 threads, delivering ample processing headroom for handling large-scale audio data with ease.

Eliminate Unnecessary Interference at the Source

A purpose-built motherboard architecture optimized exclusively for audio, combined with ultra-low-noise microvolt-level power delivery, helps preserve digital signal integrity across the board while reducing system noise at its source.

Eliminate Mechanical Vibration and Electromagnetic Noise

To prevent electromagnetic interference and audible noise caused by PWM-controlled cooling fans, ZX adopts a completely fanless thermal design. A solid CNC-machined pure copper heatsink works together with the chassis as a large passive heat-dissipation structure, ensuring stable around-the-clock operation while maintaining an exceptionally quiet background for critical listening.

CNC-Machined Pure Copper Heatsink

Break Through Transmission Bottlenecks · Expand the Soundstage

Built around the latest-generation XMOS XU316 asynchronous digital architecture, ZX is engineered for both speed and stability. Multiple dedicated LDO power rails, a physically separated board design, and an optimized shortest-path signal layout work together to preserve digital signal integrity throughout transmission.

Studio-Grade Master Clock System

Equipped with a ±0.05 ppm studio-grade OCXO master clock, ZX minimizes digital jitter to preserve the texture and integrity of the original master recording.

Massive Local Music Storage

With a dual NVMe SSD storage architecture, ZX combines a built-in 500GB high-speed SSD with expandable storage of up to 8TB—providing a stable, reliable local music library for high-resolution audio.

Built-In SSD

Independent M.2 NVMe Expansion Bay

Supports PCIe 3.0 ×4 2280 SSDs with capacities up to 8TB. The flush-mounted cover integrates seamlessly with the chassis while helping keep stored data secure.

Comprehensive Support for Ultra-High-Resolution Audio

A full array of digital outputs supports resolutions up to DSD512 and PCM 768kHz/32-bit, providing flexible connectivity with a wide range of high-end DACs.

Physically Isolated Dual LAN

Network noise can compromise streaming performance. ZX employs two physically isolated network paths to separate audio traffic from system operations.

  • One dedicated to clean, high-resolution audio streaming
  • One dedicated to background system services


By isolating external network interference, ZX helps preserve stable, precisely timed data transmission for high-resolution music.

Adaptive Grounding for Complex Systems

Ground-loop noise can become a major issue in multi-device audio systems. With one-touch grounding mode switching, ZX adapts to different system configurations to provide a cleaner ground reference and reduce mains-frequency hum caused by ground loops.

 

Whether used in older residential electrical environments or complex multi-component racks, ZX helps maintain a quieter, darker background for critical listening.

Proprietary VitOS System

An upgraded app experience is coming soon, with low-load scheduling optimized specifically for Hi-Fi playback to help maintain clean, interference-free audio performance.

Through the dedicated VitOS Orbiter App, ZX integrates leading music services from around the world, including QQ Music, Qobuz, TIDAL, Amazon Music, and Spotify Connect. Enjoy convenient access to extensive online music libraries without relying on physical CDs or lossy Bluetooth transmission—making music discovery, selection, and playback easier than ever.

Rich Streaming Ecosystem · Ready to Play

  • With Roon Core built in, there is no need for an external NAS or computer. Powered by strong onboard DSP processing, ZX handles real-time audio transcoding and system-wide upsampling with ease.

  • Combined with the fully upgraded VitOS platform and extensive lossless streaming services, ZX integrates seamlessly into a whole-home Hi-Fi ecosystem—putting comprehensive music access and control at your fingertips.

Independent Multi-Room Playback Without Interference

  • Supports simultaneous lossless playback to up to 10 endpoints, with independent output for each room. Music selection and volume can be controlled separately, while high-bitrate audio remains smooth even during synchronized multi-room playback.

  • A dual-redundant firmware design helps prevent update-related system failures, while a hybrid thermal solution minimizes heat-related performance degradation and supports stable 24/7 operation.
