Integrated amplifier LEAK Stereo 230 by IAG Limited has built-in ESS9038Q2M DAC served by XMOS controller. It supports both DSD Native and DSD-over-PCM (DoP) operational modes. But it doesn't work properly by default and tries DSD-to-PCM conversion. USB quirks below allow it to operate as designed.
