We are talking about the DeMag unit, right? Furutech also makes a product that removes static. I think that is called the DeStat.
I use the Zerostat for static and a bulk tape eraser for demagnifying an LP because both are cheaper than the Furutech products.
I agree with everything Benjie wrote, but I think he is describing the DeStat not the DeMag. I have heard Ebm's system and he owns both Furutech products - lucky guy.
