I posted a fun discussion on my blog to get into the details of this turn-on phenomenon.

When turning on  digital I always leave on , 

then preamp ,then amplifier,

when shutting off , Amplifier then preamp, in that order is the correct way.

that thump is DC still on the line,  do you have a tube preamp ?

if so follow this sequence.
