I have JBL SLR305 monitors which always pickup pops when AC, fridge or dishwasher turns on/off. A loud pop. Nothing else or any other transformer based amps I have do this so I put it down to a cheaply made switching power supply in those JBLs which picks up noise from power line. I tried different sockets around the room, extended cord to other room but nothing has any effect.
Is there anything I can do apart from getting isolation transformer? Some years ego I had one which I used to eliminate ground loops but it was always buzzing when it was on which was really annoying in the room.
I read people talking about ferrite ring on power cord but I'm not too sure if that could do anything at all for mains power, possibly just a snake oil.
