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.
Thx

Thanks for all advice.
Normally I turn off all gears before changing any cables, but I am about to play around with different speaker cables and IC cables with different power amps and preamps, and found out that it is hard to compare the sonic differences before and after changing cables if I power off, wait for a few minutes, and then power on.
I will follow the safe route most of times, but if I need to, I will change cables with preamp set to mute and input selector set to an unused input.
