ONIX BETA XI2
Portable DAC and Tube Headphone Amplifier
The ONIX XI2 Beta is a high-end USB dongle DAC/AMP designed for portable audiophile performance. It features two Cirrus Logic CS43198 DACs supporting up to 768 kHz/32-bit PCM and DSD512 formats, paired with two JAN6418 tubes for a rich, customizable sound. Users can switch between transistor and tube modes, with a balanced output power of 550 mW @ 32 Ω. The amplifier section includes dual OPA1662 and four BUF634A chips for precision in a compact form. Despite its performance, the Beta is optimized for low battery consumption and wide compatibility with UAC 1.0/2.0.
Made from aluminum with microphonics-free tube suspension, the XI2 Beta features 3.5 mm and 4.4 mm outputs, a USB-C connector, and a 0.87” screen for on-device settings. Hardware buttons provide quick volume and playback control, while a multi-color LED indicates sample rates. The Eddict Player app enhances usability, and the included ONIX OL1 silver-plated copper data cable ensures quality connection.
The XI2 Beta is not a direct successor to the XI1 Alpha, but builds on its popularity to further develop the ONIX portable Hi-Fi concept. The product weighs 45.3g.
