SMSL D10 Portable USB DAC/Amp — Dual CS43131 DSD256 32bit/384kHz

Take High-Res Audio Anywhere

The SMSL D10 is a pocket-sized portable USB DAC and headphone amplifier that punches far above its weight. Built around a dual Cirrus Logic CS43131 DAC architecture with support for DSD256 and 32-bit/384kHz PCM, it delivers exceptional clarity, a deep black noise floor, and enough output power to drive everything from sensitive IEMs to full-size headphones — all from a device that fits in the palm of your hand.

Dual CS43131 DAC Chips: True High-Fidelity Core

At the heart of the D10 are two Cirrus Logic CS43131 DAC chips working in tandem. This flagship-grade silicon delivers a signal-to-noise ratio of 121 dB and an ultra-low THD+N of just 0.00015%, ensuring your music is reproduced with stunning accuracy, micro-detail retrieval, and a pitch-black background that lets every nuance breathe.

Hi-Res Audio, Fully Decoded

The D10 is a native DSD256 hard decoder with full PCM support up to 32-bit/384kHz. Whether you are streaming lossless tracks from TIDAL, playing high-resolution FLAC files, or running DSD masters, the D10 handles it all with zero downsampling and bit-perfect precision. The USB-C interface ensures wide compatibility with Windows, macOS, Android, and iOS devices.

3.5mm and 4.4mm Balanced Dual Outputs

Versatility is key for a portable setup. The D10 features both a standard 3.5mm single-ended headphone jack and a 4.4mm Pentaconn balanced output. Use the 3.5mm for everyday listening with IEMs, or switch to the balanced 4.4mm connection for higher output power, improved channel separation, and a lower noise floor with compatible headphones and aftermarket cables.

Surprising Power in a Compact Package

Do not let the size fool you. The D10 delivers up to 500 mW per channel into 16Ω and 32Ω loads — enough to drive demanding headphones with authority — while maintaining clean output across the full impedance range: 160 mW @ 150Ω, 80 mW @ 300Ω, and 40 mW @ 600Ω.

Pocket-Ready, Travel-Friendly Design

Measuring just 55 × 11 × 20 mm and weighing a mere 17.5 g, the D10 is smaller than most USB flash drives. It draws only 200 mA over USB-C (5V), so it will not drain your phone battery. Toss it in your pocket, your headphone case, or your laptop bag — high-fidelity sound goes wherever you do.
