Hi Checkler

Yes it’s okay to replace your power cords for the Beolab 28. It has its own power supply built in.

About the humming on volume change. I assume you have connected the 28’s over powerlink? I have experienced it when i used the wrong cable on the 28’s and 17’s. You need a good shielded cable that’s verified by your local B&O dealer/cable pusher or (if I remember correctly) an Ethernet cable CAT 7 also has the desired shielding that can get the job done. I found out that the shield works as signal ground and weird things happen when you don’t have a common ground.

Hope it helps solving your humming problem
