Ground loop hum from dCS Lina and clock connected to Naim Supernait3 and Hi-capDR

Hi all,
I have eliminated this using a single shared iFi SilentPower GND defender for both DAC and clock using a short Y-shaped IEC adapter into the wall above the Naim gear leads. This works, but I understand the dCS cases aren’t grounded unless there is a GFI. dCS DAC connected by Witch Hat Morgana RCA>DIN IC.

I understand the Naim SN3 uses star-grounding and expects an earth ground from the source signal. Please let us know if you have a more elegant solution for this issue. For me, grounding the Phono ground on the SN3 to the female DIN socket had no effect.

Thanks and best wishes,
Eric
