I checked all connections and screws while i had mine open and one connector wasn't snapped all the way in and tighten all the power and dac board screws, some were...loose....and reset to factory defaults and was good to go.... ! 👍🍺🔈🔉
The ESS Sabre dacs are rotten, the worst are the ES9028 and ES9038. The ones that sound the best are the ES9018K2 and the ES9016, used on the Moon 650D ($9000).
