Found the problem with the XTZ 12.17 Edge. If I plug both sources in (Topping MX3S and Denon X1700H) the Subwoofer gets very quiet. If I use an Antimode in between it works. Very strange behavior. I contacted XTZ Support but till know they just asked some question and didn´t seem all that helpful or willing.
I also have an Arendal 1961 1V here. Sadly this one goes crazy on the grounding. As soon as my Graphics Card does some work (and even in idle a little) it gets a very very bad humming. Even with the Antimode in between nothing changes. Arendal Support is superb but I dont think they can help me with this one. So I´ll have to sell the Arendal it seems.
Edit: The Arendal support came trough for me. They suggested to tape over the grounds on the power cable from the 1961 and by god it worked perfectly. The homepage states that should not be an issue since the sub is also isolated on itself or something like that. I´m really happy now since the 1961 1V is endgame for my setup. I cant fit anything bigger and i dont think there is any subwoofer in white that would top this one for my 50m³ room.
