It sits at the heart of the Zenith line, engineered to extract fine detail and natural tone from digital sources while giving headphone listeners a genuinely powerful output stage. An in-house I\/V conversion circuit using eight OPA1611 op-amps, paired with Talema transformers and Vishay capacitors, reflects a design focused on clean power delivery and low noise.\u003c\/p\u003e\u003cp\u003eConnectivity is comprehensive. Optical, coaxial, AES and BNC inputs accept up to 192 kHz\/24-bit and DSD64, while I2S and USB reach 768 kHz\/32-bit and DSD512. The FPGA-assisted I2S input offers ten pinout modes for flexible matching to modern transports, and a 3.4-inch touch screen makes configuration and playback status easy to read at a glance. Balanced XLR and single-ended RCA outputs let it feed a wide range of amplifiers and preamplifiers.\u003c\/p\u003e\u003cp\u003eThe XDA20 is designed to pair natively with the ONIX Zenith XST20 transport for DSD over I2S.
