It seems that you do not have a true Balance connection at the socket. Research "Pin 1 Problem" in Grounding scheme and you will get your answer.
Possible group loop with balanced cables
Hi. I hope some one with more experience can offer some advice. I just replaced some single-ended cables with balanced. The balanced cables run from my DAC to preamp and from pre-amp to amp. The single ended cables still in the system are a digital coax from my CD to the DAC and from my TT into the preamp.
The balanced cables seem to have introduced a ground loop hum into the system. Is this likely? Is the fact that I have a mix of balanced and single-ended cables part of the problem? Any insights are appreciated.
