Vinyl static ionizers who's used them?

Yes, it makes sense until actual data reveal it is not happening.  Which we have first from Shure Corporation who wrote a paper on the mechanism of static charge on LPs where they reported their own experiments that showed no evidence to support the notion that friction between stylus tip and groove causes charge accumulation, and second from one of the responders to this thread who measured static charge on his LPs before vs after play, using a quality meter to do so.  He also found no difference, comparing before vs after.  So maybe you want to consider our data incomplete, but I tend toward believing that the data we do have say the idea is wrong.

James H. Kogen, Phonograph Reproduction 1978, Audio Magazine May 1978, Audio-1978-05.pdf (worldradiohistory.com) goes into some detail on static; what causes it and what does not – the needle in the groove was not a source of static.

Did anyone else buy the Acaia ion gadget? Mine is being shipped. 

I procrastinated on the Acaia, but I did buy an FMX003 static charge meter sold on eBay for $175. First experiment was to rip an LP out of its sleeve as rapidly as possible. Charge on the LP surface read -11kV. I then zapped the LP with my 50 year old Zerostat. This reduced the charge to about -0.25kV. So now I’m wondering why I need the Acaia or a Destat III or etc.

Play the LP and test for static again. The Destat is only good for about the 1st 5 minutes of the record and then it gets charged again.
