I have no issues with the "crackles" on DL300 at all (at least for now). Daily usage output mode - 32/384. Switching Dolby Atmos for Headphone on and off, playing DSD, MQA and Hi-Res, go to sleep and wakeup PC - all scenarios works well.
I think the reason for the "crackles" is most likely due to the connected devices, the motherboard, or the USB cable.
