Plug in preamp while amp is on caused very loud pop on speaker.

Did something really stupid this past weekend when I tried to rearrange the power cords and cables.  Unplugged my preamp while leaving the amps on and when I plugged back the preamp there was a very loud pop coming from my speakers.  The speakers played fine but is there any thing I should be concerned about the potential damage to the speakers?  Any suggestion is greatly appreciated.

Okay, my turn.  I plugged a speaker level output* from one amp into the output of another power amp.  Blew up all the output transistors in the second power amp. 

*or maybe that was a line output into another line output ?  Have succeeded in forgetting the details.

“on: pre>amp off: amp>pre”

So when using 12V DC triggers to your Amps from the Pre-Amp the power on order is satisfied, but not the power off? 

This is the way I’ve had it wired for ~ 17 years. Am I risking anything for this convenience?

Thanks
