Amps Always On - System Power Up Sequence

i've always been advised that it's important when powering up a system to 'follow the signal', that is to say, turn on the source component first, then preamp, then power amp, as this prevents pops that are potentially harmful to the speakers.

for those that leave their amps on all the time (class d seems to favor this), how does one go about safely powering up their system? is the 'follow the source' advice from an earlier time and perhaps is no longer necessary?

I believe the regular sequence is a good, safe one to follow. But if I left my poweramps on always, the sequence would depend on whether the preamp emitted any turn-on or turn-off thumps. Mine, a c-j MET1 with automatc 1-minute turn-on mute, emits no thumps, so I just turn it on when I wish to use it; my main SS poweramps are on all the time. If my preamp thumped and I wanted to leave my poweramps on always, I suppose I'd turn them OFF before I switched on the rest of the system, then back on.

So does your preamp thump?
