Specification

ONIX Beta XI2 — Portable Hi-Fi Tube DAC/Headphone Amplifier

Dual CS43198 decoding meets JAN6418 tube musicality.

The ONIX Beta (XI2) elevates portable listening with a rare hybrid design that blends dual Cirrus Logic CS43198 DACs for pristine resolution with dual JAN6418 pentode tubes on the balanced output for an organic, analog-like timbre. An upgraded amp stage (4× BUF634 + 2× OPA1662) delivers up to 550 mW @ 32 Ω, while a 0.87" OLED, ring-LED codec indicator, and physical buttons make daily use effortless. Support for up to PCM 768 kHz/32-bit and DSD512 ensures true hi-res performance in a compact, beautifully finished chassis.

Dual CS43198 JAN6418 Tube Output PCM 768k/32 & DSD512 Up to 550 mW @ 32Ω 3.5 mm SE & 4.4 mm Balanced UAC 1.0 / 2.0 0.87" OLED + Ring LED 5 Digital Filters • 2 Gains

Key Features

Dual CS43198 DAC Chipset — Reference-grade Cirrus Logic decoding with excellent SNR and ultra-low THD, supporting formats up to 768 kHz/32-bit and DSD512.
JAN6418 Tube Balanced Output — Discrete twin pentode tubes integrated inside the chassis (subtle side windows) impart natural warmth and spatial bloom on the 4.4 mm output.
Upgraded Amplifier Architecture — 4× BUF634 high-speed buffers + 2× OPA1662 op-amps deliver authoritative drive, dynamics, and control.
Dual Headphone Outputs — 3.5 mm single-ended (solid-state path) and 4.4 mm balanced (tube path) to complement different headphones and signatures.
Intuitive UI — Physical keys for volume/settings, 0.87" OLED shows sample rate, filter, gain, and status; ring-LED colors reflect active format/sample rate.
Portable & Refined — Elegant, rugged body that’s slightly longer/wider than XI1 to accommodate the upgraded stage; ~45.3 g for everyday carry.
Flexible Connectivity — UAC 2.0 for hi-res on modern OS; UAC 1.0 mode for broader compatibility with consoles and legacy devices.
