SMSL Audio D400 Pro Bluetooth DAC

Exquisite Sound Quality

The D400 Pro stands as a testament to SMSL's dedication to audio excellence. Anchored by the single AK4499EX chip, this DAC is engineered to support MQA decoding and MQA-CD. Its 3rd generation XMOS XU-316 ensures flawless processing of high-resolution audio files, supporting PCM up to 32bit/768kHz and DSD up to DSD512. The innovative use of flagship DAC chips—1 AK4191 and 1 AK4499EX—pushes the boundaries of sound, achieving an extraordinarily low distortion rate of just 0.00006% (-124dB).

Precision Engineered

At the heart of the D400 Pro's impeccable audio fidelity is the CK-03 clock processing circuit, designed to significantly reduce clock jitter. This is bolstered by the use of 5 high-end dual op-amps alongside a plethora of audiophile-grade components. With the addition of a 2nd PLL, the D400 Pro effectively eliminates JITTER during SPDIF transmission, offering a pristine sonic experience.

Versatile Connectivity

Embracing versatility, the D400 Pro features a full suite of inputs and outputs to cater to any audiophile's needs. USB, optical, coaxial, AES, and I2S ports all support DSD transmission, with coaxial and optical ports also supporting DOP64. The inclusion of a tempered glass full lamination colour IPS display not only enhances the user experience but also adds a touch of sophistication to the device.

Wireless Freedom and High-End Construction

Wireless connectivity is rendered in high fidelity, thanks to the Qualcomm high-end Bluetooth chip supporting LDAC (24bit/96kHz), APTX/HD, SBC, and AAC. The build quality is exceptional, with a high-quality all-aluminium alloy shell and premium gold-plated input and output terminals, affirming the D400 Pro's position in the upper echelons of audio equipment.

Certified Excellence and User Convenience

The D400 Pro is not only a feat of engineering but also a piece of certified excellence with the Japan Audio Association (JAS) Hi-Res certification. Ease of use is guaranteed with the included remote control, providing a full-featured command of your listening experience from the comfort of your chair.

Elegant Design

Available in silver and black, the D400 Pro is designed to blend seamlessly into any high-end audio setup. The aesthetic is both modern and timeless, ensuring that it not only delivers superior audio performance but also complements the visual dynamics of its surroundings. With the D400 Pro, SMSL promises an unmatched auditory journey that is as pleasing to the eyes as it is to the ears.
