Hi, has anyone experienced this problem?
The Devialet is connected via Goldkabel interconnect to a Marantz AV receiver.
As soon as I switch the source to line-in there is a constant noise coming from the loudspeakers (no noise from other sources). The noise disappears as soon as I unplug the interconnect cables from Devialet.
The strange thing is the noise is there even when the Marantz isn’t connected with a power cable at all.

Is the Marantz connected to any other equipment? First thoughts are that it could be a ground loop. What kind of noise it is - e.g. mains buzz/hum or something else?

Like white noise? Pink noise? Hum? Buzz? RCA plugs both ends?

I would guess the noise is more prominent with the Marantz off as the output from it is not terminated with active electronics. So you'd get silence when you remove the cables from Devialet (or the Marantz...). What is the noise like with the Marantz on?
If this is a ground loop you'd need an isolation transformer between the Marantz and Devialet to create galvanic isolation.

Are Marantz and Devialet connected to your Niagara 5000? That could solve the groundig prob.
What’s with the noise by disconnect your antenna cable? Stiil the same noise level?

Yes both Devialet as well as Marantz are connected to High Current slots on the Niagara 5000.
Garth Powell suggested trying having on Devialet at the same ground level (in group 1/2 or 3/4) might help. Disconnecting the antenna cable just minimal decreases the noise. But not using the HMS Isolator between antenna cable and TV massively increases it.
Trying the suggestion of Garth - but really interesting how much things interfere with each other.
