Tanchjim Space II Portable USB DAC/Amp with Dual CS43131

Looking for a portable USB DAC/Amp that can turn your phone or laptop into a genuine high-resolution audio source? The Tanchjim Space II is a pocket-sized dongle DAC built around a dual CS43131 chipset, giving it the resolving power and driving strength to handle everything from sensitive IEMs to demanding over-ear headphones.

As a compact Tanchjim DAC amp, the Space II supports PCM up to 32-bit/384kHz and native DSD256, so your music library plays back with the detail and dynamics the recording was meant to have — no bloated desktop rig required.

Whether you're commuting with a smartphone, working from a laptop, or gaming on a tablet, the Space II slips into your setup through a single USB-C cable and immediately upgrades your sound. It's the kind of upgrade that's easy to carry and even easier to hear.

Key Features

• Dual CS43131 DAC Architecture — Two dedicated DAC chips work together to deliver clean, detailed, and natural-sounding audio with very low distortion, so vocals and instruments come through with real clarity.

• TANCHJIM PureBridge USB Chip — A custom USB bridge chip maintains a stable digital signal path, ensuring your high-resolution files play back reliably without dropouts or jitter.

• Dual Output Ports (3.5mm SE / 4.4mm Balanced) — Flexible connectivity means you can pair the Space II with both standard single-ended IEMs and balanced headphones for a fuller, more separated soundstage.

• Up to 235mW Output Power — Strong driving power lets the Space II push harder-to-drive headphones with headroom to spare, avoiding the flat, underpowered sound cheaper dongles often produce.

• Hi-Res PCM & DSD256 Support — 32-bit/384kHz PCM and native DSD256 decoding preserve fine detail and dynamic range straight from your source files.

• Built-In DSP Presets — HiFi, Gaming, and Virtual Soundstage presets let you tune the sound signature on the fly depending on whether you're listening to music, gaming, or just want a wider stereo image.

• Wide Device Compatibility — UAC 1.0/2.0 support means it works across a wide range of smartphones, tablets, and computers without extra drivers in most cases.

Why Choose This Product

The Tanchjim Space II stands out because it doesn't force a trade-off between portability and performance. Most dongle DACs cut corners on power output or resolving detail to stay small — the Space II keeps both, thanks to its dual CS43131 setup and up to 235mW of output power.

As a portable DAC amp, it's genuinely small enough to leave clipped to a phone case or dropped in a pocket, yet it drives a much wider range of headphone impedances (8–300Ω) than typical phone-level output. The dual output design (3.5mm and 4.4mm) also means you're not locked into one type of cable or headphone — it adapts to whatever gear you already own.

For anyone tired of thin, compressed-sounding audio from a phone's built-in DAC, this is a practical, everyday upgrade rather than a niche audiophile purchase.

Best Use Cases

• Commuting & Travel — Lightweight enough to carry daily without adding bulk to your bag.

• Home Listening — Pairs with a laptop or desktop for a proper desktop-audio experience without a full stack.

• Gaming — Dedicated Gaming DSP preset sharpens positional audio cues.

• Students & Professionals — Useful for calls, focus music, and long listening sessions from a single USB-C connection.
