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.

If muting is available does this mitigate risk?

I’m not arguing with the safer practice being to power down gear first but agree with the OP, it’s inconvenient, especially if tubes are involved.  

I’m guilty of doing IC and speaker cable changes while gear is powered up (though not speaker cables on a powered up tube amp).

My practice has been to switch preamp selector to an unused input (if changing an IC), turn volume to zero, and activate muting on both preamp and amp. Less risky?
