16-channel flagship Delta Sigma DAC

The SU-10 DAC is SMSL’s 2022 flagship Delta Sigma DAC. Utilizing two ES9038PRO DAC chips, the SU-10 boasts 16 channels and 21 op amps for an exceedingly detailed sonic experience. SMSL has designed a third generation DAC circuit for the occasion, offering an incredibly low THD+N of 0.00005%. 

Dual linear power supplies

The digital and analog components are supplied by separate linear power supplies. This, accompanied with shielded, low-noise power supply processing, results in noise as low as 1uVrms. 

24-bit Bluetooth

Equipped with Qualcomm’s latest Bluetooth chip, the SU-10 supports 24-bit/96kHz Bluetooth formats.

3rd Gen USB controller                        

A third-generation XU-316 USB controller supports 32-bit/768kHz PCM, native DSD512, and DoP.

Tempered glass display

A tempered glass display panel provides high light transmission and extremely long service life. 


Both USB and SPDIF inputs support MQA and MQA-CD formats, giving you more options to enjoy your library at the highest quality. 

Six inputs

With inputs for USB, optical, coaxial, Bluetooth, I2S, and AES, the SU-10 supports an incredible number of sources: laptops, smart phones, TVs, gaming consoles, PCs, CD players, and more.
