For the Dac magic balanced opamp output, your connection will be short the netgetive opamp output.
It will make the power unbalanced!
So, that's why I am not connect the natgetive output to the GND.

請問......
樓主現在            source (DAC) XLR > RCA (AMP)
1號位焊銅網及地線, 2號位焊正線 XLR> RCA (正 , 地 , 無焊網)

如果我係            source (DAC) RCA > XLR (AMP)
       應該,正 , 地+網RCA >1號位地線 , 2號位焊正線 XLR (無焊網)

這樣調轉也可以?

RCA to XLR 係有問題架吾可以咁用, 因為XLR 接收級用個差動放大或輸入牛!
如只入單邊信號會有noise 架!
