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.

Does it still pop when the volume is turned down?

There is a mute button on my preamp, and also one on my phono stage.
So I have choices.
Yes, check or replace capacitor across TT on/off switch. And you are right; Amps on last and off first.
Ah or maybe a flyback diode if it is back EMF?
We have always done:

 AMPS: on first, off last.
t startup I do:
  1. Preamp on first, with its mute button in from when I urned it off.
  2. Then amplifier on.
  3. he preamp mute disabled.

At shut down:
  1. Preamp mute
  2. Amplifier off
  3. Preamp off
Pop on turn off sounds more like a back EMF problem, than a static problem.
