Mihilli, I believe its a standard 3/8" thread... Mainly I believe a lot of the fuss here is that the Height in fact changed the soundstage quite a bit.. The Original spikes only raised them about a Half inch or so, but you could maybe get them to go about 3/4" out of the cabinet from the floor.. I just simply found the Solid 2" Height better period, whether it is due to it being Starsound material, Brass, Or just a beefier spike is really not explainable by me accept they just simply worked better overall and sounded a little more clear, solid and yes much easier to place the cabinets, and they are much much Tighter fit to the body of the speaker with A much more Solid platform it seems. Try something out it can't hurt, How much this is worth Funding wise, well thats the real justification in the end and up to you.
