Meet the SMSL D400 Pro—your High-Resolution USB Desktop DAC with unparalleled performance and versatility. With its top-of-the-line AKM DAC chips, MQA certification, and a plethora of input and output options, this DAC isn’t just another component in your audio setup--it’s the cornerstone.

Unlocking the purity of audio with flagship AKM DAC Chips

Utilizing not one, but two flagship AKM DAC Chips—AK4191 and AK4499EX—the SMSL D400 Pro reduces harmonic distortion to a jaw-dropping -124dB THD+N. This feature guarantees a level of sound quality that is as pure as it gets, letting you hear every nuance and subtlety in your music.

Crystal clear operation with CK-03 Clock Processing Circuit

Timing is everything in audio. The new CK-03 clock processing circuit dramatically reduces clock jitter, ensuring that each musical note is delivered with razor-sharp precision.

Zero noise, maximum impact with built-in low-noise power processing

The built-in low-noise power processing system features multiple regulated power supplies. This ensures that your DAC operates in an environment free from electronic "noise," allowing the purest sound reproduction possible.

Living for the connection with high-quality gold-plated terminals

Quality doesn’t stop at internal components. The SMSL D400 Pro boasts gold-plated input and output connection terminals, ensuring the highest signal integrity and minimizing potential signal degradation.

Cutting-edge aesthetics

A scalloped front and fully laminated display bring aesthetic excellence to your audio experience. The fully laminated tempered glass display panel not only looks stunning but also offers high-end durability.

Cutting the cord while keeping the fidelity

The Qualcomm’s high-end Bluetooth chip provides wireless connectivity that supports LDAC 24bit/96kHz, APTX/HD, SBC, AAC, all while maintaining an effective range of up to 15m. Go ahead—wander a bit while enjoying your favorite tunes.

Remote control that’s not remotely difficult to use

The compact, durable, and full-function remote control lets you command your audio experience with ease. The controls are intuitive, making it a breeze to adjust settings—even if your audiophile journey is just getting started.
