Subwoofer unplugged while still on.

Might depend on the amp more than anything. You could potentially get a big POP which could potentially damage speakers. This is why sequencers exist. Unplug or even turn off a MiniDSP with everything else being on and apparently this will happen.

Not the same thing.

 

If we are talking about input cables then yes but just unplugging the power should not harm anything.

 

My apologies, I thought you meant power cord.

 

If RCA, then things "could" go awry.  Not a good practice.

It's not like no amps ever thump when you turn them off. Pull the plug and they'll do the same thing. Lots of amps have relays and soft start circuits so during normal use you'll never hear anything.

The question is more about whether it's damaging or simply annoying even if this does happen. Typically I imagine it's simply annoying, especially on subs.

The red spade audio blog from Paul Spencer is excellent and if he says an amp can thump when turning off or losing power, I'm not sure why anybody here would question it.
