Use the cheater plug to see if that is the problem. If that cures the problem find the reason for the ground loop and fix it. By using a cheater plug you are lifting the safety ground.
Good small/single outlet power conditioner for preamp.
Anyone know what’s out there?
I am demoing a very nice preamp but it, for currently an unknown reason, does not play well with my Puritan PSM156 conditioner. The pre exhibits noise/hum from the speakers with any source ICs plugged into it.
But the preamp straight to the wall is hum free and all is fine.
If I wanted to keep this pre, straight to the wall is not ideal. So I am preliminarily curious what nice small/single outlet power conditioners are out there for me to consider…
thanks
