Ground loops are not created by a component but by a system and how it is interconnected. All DACS can form part of a ground loop (as can any other component in the chain) unless they include galvanic isolation. I am not aware of any that do.OK, thanks. So ground loops can be easily created using this DAC.
You don't need to use a isolator, or other mitigation unless you experience noise - hiss or hum, which is audible at your normal listening volume.
