Building up Zenith Line

XDA20 is the second device to join our Zenith line, a dedicated range of products focused on High-End desktop and speaker Hi-Fi setups. XDA20 represents the High-End DAC to be paired with the previously released XST20 SACD Transport and upcoming XMT20 Streamer.

High-End DAC Assembly

The ONIX XDA20 draws inspiration from our ONIX Miracle System and features the same ESS Flagship DAC, the ES9039Pro. However, for the XDA20, the DAC circuit got upgraded to a pair of these amazing top-grade DACs and utilizes eight pieces of OPA1611 in our in-house developed I/V Conversion Circuit.

Superior Power Supply

Clear and stable power is the key to true high fidelity sound, which is why XDA20 comes with combinations of 15W & 25W Talema transformers and the superb Vishay capacitors for power filtering.

Advanced I2S Input

We designed the Zenith line to create the ultimate Source – DAC pairing, utilizing the immaculate I2S connection between the devices. As such, the XDA20 performs at its best when running from the I2S input, ideally when combined with out XST20 or XMT20 transports.

But to ensure compatibility with other I2S transports on the market, we added our special FPGA-assisted I2S circuit into the XDA20, offering 10 different pinouts for easy matching with all types of transports.

Multifunctional Heart of System

For XDA20, we focused on its performance as a High-End DAC, offering the best sound on its RCA & XLR outputs, running either in the pure line-out mode or acting as a pre-amplifier for the speaker setup.

For the fans of headphone listening, we implemented a compact TPA6120 headphone amplifier, offering decent power up to 1.6W @ 32 Ohm on its 6.35mm output.

And a range of digital inputs then assures compatibility with all your other components, including dedicated XMOS XU316 USB input for direct use with computers.

Classic ONIX Look
