Vinyl static ionizers who's used them?

Have now seen one of the CS Port ionizers in action and wow it does work. These are all sold out but I'll get one after saving some pennies.

The ad for CC Port says “static electricity is caused by cartridge friction.” So far as can be determined by a search for actual data, that’s incorrect. DS Audio make the same claim in their ad copy. Doesn’t matter if both products perform, but it’s good to seek a valid hypothesis.

Well as you stated lewm that's CSPORT & DSAUDIO hypothesis right or wrong. It makes sense that some of the static would be caused by the cartridge "dragging" in the Grove but I'm sure there is more to it than that.

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.
