What to fill Skylan stands with for Harbeth SHL5s


Skylan stands for SHL5s: could someone please tell me what to fill them with?
Skylan advised PURINA MAXX kitty litter, but I cannot find this in the U.S.
Should I use play sand, sand kitty litter, clay kitty litter, something else?
Thank you.

I used sand on my Skylan stands ( 20" high 4 post ) filled aprox 2/3..I used construction sand ( in tubular bags )...Its a larger sized sand and works great..The real trick is to not over fill...You can over do it..I found 60-70% worked best for me...You can try 50% and always ad more if you need to......I also found that using the Big Fat Dots ( or similar ) for transition between stand and speakers works well...
I believe that Noel at Skylan recommends clay kitty litter. Try calling him and asking; he's a great guy and easy to deal with.
I used a combination of lead shot and playground sand in my Target stands, and secured my Dyn. 1.3SE's with the Elmer's version of blue-tak. It worked great.... a very heavy and secure way to set up monitors. I've since moved on to floorstanders, but would use this same set up if/when I go back to monitors some day.

Speaking of monitors.... How do you like your Super HL5's, and what are you driving them with (amp & pre)? I've always been intrigued by them.
Excellent question, I just finished my own 4-pillar stands very similar to Skylans, except my posts are 3" round instead of square pvc and 26" high.

I'm filling mine with #9 Lead Shot on the very bottoms, (about 15-20%) then finishing with Silica Sand (to approx. 70% height of the posts) to prevent top heaviness.
