The ONIX Zenith XST20 is a high-end SACD/CD transport designed for audiophiles who want the purest disc playback into their favorite external DAC, delivering true SACD DSD output, premium top-loading build quality, and exceptional connectivity—especially for I2S-based high-end systems.
Features
- Plays CD, SACD, & MQA-CD
- DoP DSD Output Support
- FPGA-Based I2S Output
- Built for External DACs
- Low-Noise Stable Playback
- Pure Transport-Only Design
True SACD Playback with Real DSD Output
The XST20 is built to unlock the full potential of SACD discs, allowing playback in true DSD quality to compatible external DACs. It supports SACD output through I2S for native DSD64, and can also deliver DSD64 via DoP over digital outputs like coaxial, optical, AES/EBU, and BNC (while USB output does not support SACD).
Wide DAC Compatibility with 10 I2S Pinout Modes
One of the standout advantages of the Zenith XST20 is its FPGA-assisted I2S output, which includes hardware switching across 10 I2S pinout modes. This greatly improves real-world compatibility across the wide variety of I2S-equipped DACs, making it far easier to integrate into high-end systems without guesswork.
Highly Optimized Disc Drive + Gapless Playback
The XST20 uses a precision, audiophile-focused transport design to deliver smooth, stable playback with seamless track transitions. It supports single-layer SACD, multi-layer SACD, standard CDs, and MQA-CDs, with fully gapless playback for uninterrupted album listening.
Top-Loading Design with Premium Build Quality
Designed like a true high-end component, the XST20 features a top-loading transport approach and premium mechanical construction for reliable operation and consistent disc reading performance. It’s engineered to provide the stable, focused signal extraction audiophiles expect from a dedicated disc transport.
Full Digital Output Suite for System Flexibility
To match modern high-end DAC setups, the Zenith XST20 provides a wide range of digital output options including I2S, coaxial, BNC, AES/EBU, optical, and USB, making it easy to connect to nearly any external DAC or digital audio system.
