Hi X.G.,
Thanks your infromation and advice.Yes,my friend told me also the same problem about switches other equtment will cause unlock. I can see the photo of your DAC's digital input and output connection without a digital transformer.Right?I think it may has insulation problem between digital signal and grounding. Adding a digital transformer may help for unlock.

yes.but the DAC is not mine and had saled,have no chance to try yours.
