MEET THE Onix
A top-loading SACD/CD transport that plays SACDs in true DSD to your DAC, with FPGA-assisted I2S and a 3.4-inch touch screen.
Plays SACDs as native DSD64 over I2S, or DoP over coaxial, optical, AES and BNC.
A top-loading design with a classic clamp for single- and multi-layer SACDs, CDs and MQA-CDs.
FPGA-assisted I2S output for matching with a wide range of high-end DACs.
The ONIX Zenith XST20 is a top-loading SACD and CD transport for a separate DAC, the first model in ONIX’s high-end Zenith line. It plays SACDs in true DSD, either as native DSD64 over I2S or as DoP over coaxial, optical, AES and BNC, and its FPGA-assisted I2S with ten pinout modes means it works with almost any I2S DAC.


Many transports can’t send the DSD layer of an SACD to an external DAC. The XST20 can, to any DSD-capable DAC. It supports single- and multi-layer SACDs with layer switching, standard CDs and MQA-CDs (ONIX quotes 4x expansion), all with smooth track transitions.

I2S has no fixed standard for its pin layout, which has caused compatibility problems between transports and DACs. The XST20’s FPGA hardware can switch between ten I2S pinout modes to suit virtually any I2S DAC, alongside USB, AES, BNC, coaxial and optical outputs, so it is a good match for high-end DACs.

The XST20 focuses entirely on the best possible playback of SACDs and CDs. There is no streaming, wireless or app, just the pure lossless quality of the disc. A top-loading HD870 drive with a traditional disc clamp, a built-in 45.1584MHz clock for precise data processing, and an ultra-clean power supply with a Talema 25VA toroidal iron-core transformer sit in a sturdy chassis CNC-machined from aluminium in the classic ONIX style, with gold details. A 3.4-inch touch screen gives direct access to the settings, and ONIX’s remote control is included.
