Well, I am not a technical person, but my guess is that it stores up some power that needs to dissipate before you turn off the preamp. Wait a bit more and see if it's not gone.
What causes an amp to discharge a thump.?
I have installed a Quad 909 amp in my system amd ever since when it is shut down I here a slight thump or like a statice discharge through the speakers.
This takes any where from 5 to 8 seconds .
The order in which I turn off the equipment is the reverse of turn on, that is amp first preamp next then source.
I'm sure it is coming from the amp, but why?
Thanks for your help.
