Description Of Issue
When I listen to my music via my Nain Naît 5si, everything is perfect as soon as I listen to my Sansui 9090 I ear all the computer noise. The Nain is connected to the rca audio out and the Sansui is connected to the xlr output from the CNX.

This is strange.

When I use the radio direct on the CNX on when I use Chromecast I don’t have this problem.

Only when I use Roon and the Sansui. Anyone as a opinion.

Than you.

Édit: I forgot my basic knowledge, I just put the NUC and the switch on another circuit and everything is perfect now, with my Sansui.
It showed me that the Naim’s got a excellent alimentation stage.

Hello @jpdspin, glad things are working again! Please let me know if you have any further questions.
