Should the power be off every time changing cables?


I’m experimenting different IC and speaker cables.
Powering on and off to power amp, preamp, and other components each time changing cables is really bothering, because I need to wait 10 minutes or so between power on an offs.
I wonder I still need to turn off the power amp when I change IC cables between preamp and components. 
What kinds of cables can be changed with power amp on?
 I have a Plinius power amp and preamp.

You can make a lot of mistakes with an amp OFF, and it won't blow anything up. You make ONE mistake with an amp on, and it could be GOODBYE!  :)
