The ONIX XDA20 is the second addition to the Zenith line, a dedicated range of high-end components designed for desktop and speaker-based Hi-Fi systems. Positioned as the flagship DAC in the series, the XDA20 is engineered to pair seamlessly with the XST20 SACD Transport and the upcoming XMT20 Streamer.

High-End DAC Assembly

Drawing inspiration from the ONIX Miracle System, the XDA20 incorporates not one but two ESS ES9039Pro flagship DAC chips. Its in-house designed I/V conversion stage employs eight OPA1611 op-amps, ensuring precise and musical signal handling.

Superior Power Supply

Recognizing the importance of stable power delivery, the XDA20 is equipped with 15W and 25W Talema transformers paired with premium Vishay capacitors. This combination provides exceptionally clean power, forming the foundation for high-fidelity sound reproduction.

Advanced I²S Input

The Zenith line was conceived with the ultimate Source–DAC synergy in mind, with I²S as the ideal connection. The XDA20 achieves peak performance when paired with the XST20 or XMT20 via I²S. To extend compatibility, ONIX developed an FPGA-assisted I²S circuit offering 10 selectable pinouts, making it adaptable to nearly any transport on the market.
