The Tanchjim Space II is a compact, high-performance portable USB DAC/Amp that builds on the acclaimed SPACE series with a key upgrade: TANCHJIM's in-house "PureBridge" USB digital interface chip and DSP Sound Preset Community support — all while retaining the proven dual CS43131 DAC architecture and 3.5mm + 4.4mm dual outputs.
Dual CS43131 DAC PureBridge USB Chip 3.5mm + 4.4mm Dual Outputs 235mW @ 32Ω PCM 32-bit / 384kHz | DSD256 SINAD up to 116dB UAC 1.0 / UAC 2.0 3.5mm Inline Mic Supported ~15.1g Ultra-Compact
TANCHJIM "PureBridge" USB Digital Interface Chip
The Space II's most significant upgrade is its in-house-developed "PureBridge" chip, which handles USB data reception, UAC protocol management, audio stream processing, and clock domain management before the signal reaches the DAC. This independent data preprocessing stage ensures a stable, clean digital input for the downstream dual CS43131 DACs, reducing transmission-stage variables and improving overall signal integrity.
Dual CS43131 DAC Architecture — Proven, Low-Power, High-Performance
The Space II retains the SPACE series' trusted dual CS43131 DAC configuration. The dual-DAC architecture supports both 3.5mm single-ended and 4.4mm true balanced output, providing the electrical foundation for excellent channel separation, wide dynamic range, and generous output headroom — all with low power consumption and minimal heat generation.
Benchmark-Class Measured Performance
With the PureBridge chip handling precise data preprocessing and the dual CS43131 delivering conversion, the Space II achieves low distortion, high SINAD (up to 116dB), wide dynamic range, and an extremely low noise floor. Verified by TANCHJIM's R&D department using an APx555 audio analyzer under no-load, 32Ω load, and 12kHz jitter test conditions.
3.5mm Single-Ended + 4.4mm Balanced Dual Outputs
The 3.5mm output offers wide compatibility with common IEMs and headphones. The 4.4mm balanced output delivers higher voltage swing (up to 4Vrms) and lower channel crosstalk, ideal for balanced cables and more demanding listening setups. Total output power reaches up to 235mW @ 32Ω.
3.5mm CTIA Inline Mic Support
Compatible with standard CTIA wired earphones with inline microphones, enabling clear voice calls and near-zero-latency voice chat for gaming — wherever you go.
TANCHJIM DSP Sound Preset Community
The Space II supports TANCHJIM DSP sound tuning. Apply official presets or browse community-shared sound curves to match your IEMs, headphones, music genre, or use case — music, gaming, or video. One device, endless tuning possibilities.
UAC Dual-Mode: UAC 1.0 + UAC 2.0
UAC 2.0 enables high-resolution playback (PCM 32-bit/384kHz, DSD256), while UAC 1.0 ensures broad compatibility across smartphones, tablets, computers, and handheld gaming devices.
Three New Colors — Aerospace-Grade Aluminum Alloy CNC Housing
The Space II continues the SPACE series' aerospace-grade aluminum alloy CNC-machined housing with a clear window design, now available in three new finishes: Gradient Blue (flowing starlight), Gunmetal (spacecraft-inspired technical feel), and Deep Black (the quiet depth of the universe).
Ultra-Compact & Portable
Weighing just ~15.1g and measuring approximately 4.2 × 2.1 × 1.2cm, the Space II is designed for all-day carry and extended use without fatigue.
