Another happy micro Dac user here. I tried two inexpensive HDMI cables, including the AudioQuest LGC directional HDMI, but was disappointed with the sound. Then I tested the DH Labs HDMI 2.1 cable and ended up liking/keeping it—especially after burn-in. It delivered a fuller, bassier sound than the AQ. According to Greg from DH Labs, their HDMI cables take about 40 hours to fully burn in. Also, be sure to get the 2.1 version rather than 2.0—it uses lower dielectric insulation, which reduces signal degradation and lowers capacitance for better overall performance.
