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?

If you are going to leave your amps on and you do not have tubes, why not just leave everything on ?
Tan43... Thats the way I do it , everything is on all the time , volume is down at night . Break down rate seems to be non existent . Been doing it this way for years .
Agree, if you are leaving the AMP on, you might just as well leave the preamp on. The ONLY reason i could see not to leave it on, is if the preamp is a tubed model. Though preamp tubes do not wear out nearly as fast as power amp tubes. i have a VAC Standard with four 12a? tubes and i just leave it on anyway. The VAC has not holes or openings and only gets a little warm, so the tubes seem to be lightly loaded.
My amp is connected to the Bryston preamp mute switch, so the amp turns off automatically if I turn on the mute. nice.
When I had solid state I left everything on all the time. Never any problems. Now that Ive got tubes, I turn them off but leave the source components on, (no tubes here) Ive always heard that the enemy of tubes is the surge when you turn it on. Once up and running, tubes like to stay on all the time. All the dealers, techs and other gurus tell me to turn tubes off when not listening. What do other people do in this situation
Everything gets turned off here, for two reasons. The first is the fire risk, and the second is concern for the environment. I think it is really wrong to add even more emissions, and I say this even though we produce nearly (but not quite) all our own electricity.
The proper way to deal with this is to have amplifiers that turn themselves off when they are not used, just like many subwoofers. Such amplifiers are rare, but I have one in the bedroom and it is very neat, with very low standby consumption (an Ava Maestro 50, just good enough for modest bedroom use). It is tucked away in a wardrobe and connected to a Chromecast Audio by way of its optical input. So whenever I want to hear either streamed music or internet radio, all I have to do is get out my phone. The amp is invisible, which I also like (less clutter) even if in this case it is actually very elegantly made. Why can't we have all our amps out of sight and turning themselves on and off?
Friendly tip to those new here: check out the date of the OP and/or the last response. 

Sometimes it is worthwhile to resurrect a very old thread, so if that is the case, carry on.
