Read the full description
The ONIX Zenith XDA20 is a high-end desktop DAC and preamplifier, the second member of ONIX’s Zenith line of high-end desktop and speaker components, designed to pair with the XST20 SACD transport and the XMT20 streamer. Designed by ONIX, the hi-fi brand born in Brighton in the 1980s, and made by Shanling, it takes the ESS ES9039PRO from the ONIX Miracle system and doubles it, with every digital input a serious system needs, balanced and single-ended outputs and a 1.6W headphone amplifier.
Two flagship DACs and the Brighton I/V stage
The XDA20 is inspired by ONIX’s Miracle system and uses the same ESS flagship DAC, upgraded to a pair of ES9039PROs for resolution and dynamics up to 768kHz/32-bit and DSD512. Eight OPA1611 op-amps form ONIX’s in-house “Brighton” I/V conversion stage, for a delicate sound presentation. The balanced outputs reach 127dB signal-to-noise ratio with 0.0003% THD+N.
A superior power supply
Clear, stable power is key to true high fidelity, so the XDA20 combines iron-core 25W and 15W Talema transformers with four 3,300µF/63V Vishay capacitors for power filtering.
Built for I²S
ONIX designed the Zenith line around the I²S connection between source and DAC, and the XDA20 performs at its best from its I²S input, ideally with the XST20 or XMT20. To match other brands’ I²S transports too, ONIX added an FPGA-assisted I²S circuit with 10 different pinouts.
The heart of your system
ONIX focused on the XDA20’s performance as a DAC, with its best sound on the RCA and XLR outputs, used either as a pure line output or as a pre-amplifier for speakers. For headphones, a compact TPA6120 amplifier gives up to 1.6W into 32Ω from the 6.35mm output, with two gain levels. Optical, coaxial, AES and BNC inputs, and a dedicated XMOS XU316 USB input for computers, connect your other components.
Classic ONIX look, simple control
The robust aluminium body is CNC-machined in ONIX’s classic black-and-gold style. A 3.4-inch touchscreen gives a simple, quick system, with a volume wheel and a remote control.
