Turntables thump when turning off?

Why?  I have used 4 different tables and three phono stages in 2 different systems and all of them produce a pretty loud thump when turning off especially, sometimes when turning on.  I have been muting the system each time I turn off as it seems a little much to be letting such a thump reach the speakers.  Is there a cure?  lift grounds?  arrange cables? I was getting a pretty decent hum at times and I've noticed careful routing of the cable to the phono preamp makes a huge difference in this.

What turntable? More than one brand or type? When you say “off”, do you mean power off or just platter motor off?

You solved the concern with muting. Relax and enjoy the long weekend and listen to your stereo.

The thump is loud, very loud if it's at the full volume I would play an LP at.  I guess you guys are saying it's normal and I just have to live with.  It's there no matter the table or phono stage and even does basically the same thing in a whole different system.  It's a VPI classic 3 and Rega RP8.  I had Nottinghams before and those don't turn off ever so maybe that is why I didn't ever notice until now.  You have to stop the VPI motor after every LP side since it uses the center weight and periphery ring.  The RP8 I can just snag the LP off without stopping it.

"The thump is loud, very loud if it's at the full volume"

You know what the Doctor says to patient?

It hurts when I do "x" Doctor-then don't do "x"

Contact VPI.  Some of their turntables had an issue with making a pop when powered off.  They sent me a capacitor for free for my Classic 2 and it was a pretty easy fix and resolved the issue.
