After moving to a new house I’ve built a new room with 3 dedicated powerlines in to the room + a dedicated line for lights. The room has been soundproffed so at 100dB I can only measure 35dB on the floor above, the room is very quiet so if something as humming it’s very distracting and audioble. And my P10 is humming, step in to the room an you hear it with no problem. Just having P10 plugged in with no components in standby or on you really here the hum from the transformer. So every low parts in a pice of music is canceled out from this noise. Please advise if there is a DC removing device or any trick to remove this. Before I’m forced to disconnect it and send it out to pasture (sell it). Would a P5 be a better bet as it has a smaller transformer?
I’ve had electricians, goverment power controller and the power company on sight to check if either could find any faults, ground loops. $2000 later no fault were found be any ! Even bough new fuses for the breakerbox that auto monitoring this 3 lines and detects if a faulty wire or product is hooked up.
