I get all kinds of responses that often oppose each other. If I followed everything, it would mean not to try anything at all. It might be ridiculous it’s the power line but I have to be sure.
I have read one thread here on Audiogon few weeks ago and someone stated he gave up after several months of investigation and got a solid state preamp.
It was here -
In this case the victim recognized the radio signal and it was picked up by the turntable. ;) the final solution was grounding. He even says "braided ground wires". I was told that it doesn’t make any difference if a ground wire is braided or not. Also that it doesn’t matter where you place the ground wire - because the components share the same ground.
@esarhaddon I have had this problem since I received the EAR phono preamp few months ago. I used to have a Bryston B60 integrated, at the time, I had unplugged everything, leaving all the sockets in the apartment empty. Even the fridge had to wait. I only plugged the Bryston and the EAR phono. It didn’t help.
I don’t think there’s any defective component nor is the phono preamp. It’s simply a signal from the outside. Could it be picked up by the power cables? Probably not, right, it would be the same as if it was coming from the power line.
I think if I placed my cables into a copper sleeve, grounded the sleeve and made another cage for the preamp, then it could work.Maybe the ferrite rings would do the same job as a copper sleeve.
