Amplifiers amplify! Why would you want your amp to strengthen the sound of the power supply of your preamp collapsing? Next you will be telling us that you cannot pick up your lawnmover with it running and not cut off your fingers.
Why do my speakers "POP" when I turn off preamp?
HI. Is there any way I can get rid of that loud POP sound though my speakers that I get when I turn off the preamp (and leave the amp on)? My preamp is a C-J PV10A, which is recommended to turn off when not in use, but my amp is the C-J MF-2200, which is SS and can be left on. That sound can't be good for the speakers.
