Two Cirrus Logic CS43198 DACs handle up to 768kHz\/32-bit and DSD512, and a new amplifier of two OPA1662 op-amps and four BUF634A buffers delivers up to 550mW into 32Ω from the 4.4mm balanced output, in a durable aluminium body.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/shanling-onix-beta-xi2-portable-tube-dac-amp-adapter-photo-hero.jpg?v=1791360922\" alt=\"ONIX Beta XI2 USB dongle DAC with dedicated tube output\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/shanling-onix-beta-xi2-portable-tube-dac-amp-adapter-photo-overview.jpg?v=1791360925\" alt=\"ONIX Beta XI2 features: dual CS43198, dual JAN6418 tubes, OPA1662 and BUF634A\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eA fan-favourite sound foundation\u003c\/h3\u003e\n\u003cp\u003eThe XI2 is built around the same top-of-the-line CS43198 DACs as the \u003ca href=\"\/products\/shanling-onix-xi1-high-end-dongle-dac\"\u003eONIX XI1\u003c\/a\u003e, one per channel for a fully balanced output, keeping the detailed, energetic sound that made the XI1 stand out.\u003c\/p\u003e\n\u003ch3\u003eAn upgraded headphone amplifier\u003c\/h3\u003e\n\u003cp\u003eThe biggest change is the amplifier: a more advanced design with dual OPA1662 op-amps and quad BUF634A buffers.

They sit safely inside the body, with two small windows to glimpse their glow, and a setting switches the tubes on or off almost instantly.
