Plinius noise with balanced cables

Hello gentlemen, I saw a post recently regarding some noise was experiencing with their Plinius and now I can't seem to find it.  I'll keep looking as it's no longer in my history.  Anyway, I'm experiencing some white noise with the balanced cables only, not the RCAs.  I'd like to use the balanced cables so I can also use RCAs into my headphone amp rather then having to keep disconnecting said RCAs.  I'll be bringing it in soon albeit I hate part with it.  I was hoping someone could shed some light on this in the meantime?

Thank you
