None so far.
NOTE:
If your DSDs is draining a lot of battery and exhibiting a lot of heat, you might want to turn off the "Turbo" DAC setting. That way, your DSDs will have an extended battery life and less heat.
P.S. I know the DSDs is kinda "cold" now, but due to requests and the fact that the DSDs is a different line up from the old DSD, so I decided to make it happen. And there you go, i hope this thread can be useful.
Stay healthy,
God bless
