Power Down Sequence for Amp / TT to Avoid Speaker Pop

Hello!  I have Rogue Audio Sphinx v3 and Rega P3 TT and Zu Audio Omen's. When I go to flip record side or change to another record, I turn off the TT (while the amp is ON) and I hear an audible pop from the speakers. 

I've heard you should avoid this pop (to protect the speakers), but this would mean I would have turn the amp OFF and then back ON whenever I change the record which would be a pain. Turning the TT OFF is the only way to stop the platter. And, Rogue advises not rapidly turning the amp OFF and ON to avoid "transient noises". 

What do others do here? Is the pop something to really be worried about and worth this power off / on sequence? I might be missing something as well.

I use 2 different techniques: 
1)Change the input selector in my preamp
2)Use the mute switch on my phono preamp
It keeps the switches in good operating order. 

I also have a Technics tt...which stops the platter in an instant with a brake (torque that can be adjusted). Never gave it much thought until this post. Also powering the tt on/off out of sequence won't create a audible pop.
