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.

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

as far as what to touch for grounding, something organic is best. i touch a wood shelf on my rack.
Shouldn’t one touch something metal that’s connected to the ground to dissipate static electricity, but wood is a poor conductor- am I missing something?

Pop on turn off sounds more like a back EMF problem, than a static problem.

The OP has an integrated amp. You can’t shut off the amp or preamp separately. All he has to do is switch to an other source when he turns the turntable on and off. There is no reason to turn off his Rogue every time he changes a record!

When I turn off my Sugden a21se integrated, I get the faintest of so called speaker pop,  that is with all sources already turned off. I doubt very much it is causing any issues whatsoever. It sounds great otherwise.
