NAD 3155 Pops when turned off


Have my sons college setup ready to go. He has a set of B&W 685s, NAD 3155, Audinst MX1 and Emotiva speaker cables.
Each time you turn the NAD off you get a pop through the speakers. Volume level does not matter. We spent time cleaning all the rca inputs, power plugs, buttons/knobs with deoxit and deoxit gold. That did take care of a cracking in the left channel when the volume knob was adjusted.

Is there a solution to the pop when powered off? Or is this normal with these older NADs?
Thanks in advance for your help.
