Anyone have this turntable issue?

 It seems to be the stylus entering the groove.

Right.

I agree with elizabeth, it has to be static.
With the volume control turned all the way down it must be a hell of a static charge.

What is the the percentage of humidly in the room?

Belt drive TT?
What material is the platter made of?

What are you using for a TT platter mat? You might try a cork one.

What method are you using to clean your records? Are you wiping them dry with a cotton cloth? That will build up a good static charge.

OP:

I have done everything to avoid static in the system. I'm quite sure it is not static.

elizabeth:

It has to be static. No other possible thing.

Simple enough to test. If its static then it will pop even before the stylus touches down, the instant its close enough for a charge to zap across the gap. Otherwise it will pop only after gliding over the vinyl to finally drop into the groove.

And so as Richard Dawson so often proclaimed..... "Survey says......"

Did you recently install this cartridge?
If you are using separate components, is the preamp new to your system?
You are sure with low and high volume that you are not hearing any irregularities?
Pending those answers, eliminating static is not too hard: 1. Get rid of fabric turntable mats and replace with either a cork mat which you can likely get from Amazon or otherwise from U-Turn Audio. OR you can get a Herbies Way Excellent II Turntable Mat. 2. Get a Zerostat and use it.
