Cutting-edge desktop DAC

The SMSL SU-9 Pro MQA Desktop DAC pushes the desktop DAC game forward with a set of cutting-edge components like a brand-new ESS SABRE DAC chip, a third gen jitter elimination chip, and a third gen USB controller. Plus, a number of quality-of-life improvements like an updated UI and DOP display make this DAC as incredible to operate as listen to.

8-channel flagship SABRE chip

The SU-9 Pro uses an 8-channel ESS SABRE ES9039MPRO DAC chip with a total of 11 OPA-1612A op-amps. This setup boasts an incredible 134dB of dynamic range plus stereo MQA rendering built right in.

Third generation USB controller

With a third-generation XMOS XU316 USB controller, the SU-9 Pro offers a true 32-bit USB solution, with support for PCM 768kHz and DSD512.

Built-in shielding for ultra low-noise

Achieving the incredible noise performance of 0.00005% THD+N requires a staggering degree of brilliant engineering. The SU-9 uses speciality-designed discrete components, a linear regulated power supply, several low-noise regulated power supplies, and built-in shielding. The result is a pure black backdrop for your music to shine against.

HD Bluetooth 5.0

Use your phone, laptop, tablet, or computer to stream from anywhere in your place with Bluetooth 5.0. Enjoy HD codecs like LDAC and AptX HD that support audiophile-grade bit and sampling rates up to 24bit/96kHz.

Exquisitely-designed chassis

Precisely milled with aluminum alloy, the outer shell is both stately and strong. The sharp edges have been chamfered and the shell has been anodized for an altogether smooth finish.
