The SMSL M500 box is a proprietary design with assorted erased components. The DAC onboard (M500) is the ESS9038PRO. Not sure if the MQA decoding is performed by this DAC or on the XMOS device. However, the selected DAC appears to be very high end.

ESS SABRE 9219C is another option for the DAC which does offer hardware decoding of the MQA specification.

Datasheets for both are attached.

Dear mon2, could you please send working firmware image to my address as well – me@alexkolov.com. Going to try and reflash it myself. Thanks!
