About the SU6
The SMSL SU-6 is a small desktop DAC designed for high-performance digital-to-analog conversion in a compact chassis. It uses the ESS ES9038Q2M DAC chip, a 2nd-generation XMOS USB platform, and Bluetooth 5.0 with LDAC support, making it suitable for USB, optical, coaxial, and wireless desktop setups. It also includes a remote control, internal power supply, and configurable digital filters and DPLL settings. The SU-6 was widely sold around US$169.99, but it is no longer commonly listed in current retail catalogs, so availability appears limited or discontinued.
