What to fill Skylan stands with for Harbeth SHL5s

Any clay kitty litter will do fine. I just got a pair of Skylan 4 post stands for my Monitor 30's, filled them about 2/3 full, 5 pounds per column, with unscented store brand kitty litter. I've been using kitty litter in metal stands for years. It was recommended to me by a guy who has been a high end dealer for over 30 years. At first, I was surprised that Noel recommended it, since Skylan stands don't ring the way metal stands do and it seemed to me that the only reason to fill the columns is to add weight and mass. But the more I thought about it, the more it made sense.

Anyway, the Skylan stsnds are terrific. Big improvement in bass definition, clarity, soundstaging, depth and imaging. It's like the speakers are suspended in air, but are absolutely stable. Terrific jump factor (which I noticed when my dog jumped).

Thanks for the info!

Skylan stands are awesome.

Noel is the nicest guy and really knows his stuff about good sound.

He taught me more in a half hour that I did not know for years !

Yep, talked to Noel and waiting for a pair.
Thanks!

Silica sand - THE END. Get yourself some through a janitorial firm (silica sand was always used for public high volume ashtrays). Noel is a genuine guy and his product typifies beauty in simplicity.

Coincidentally, I just the other day listed one of Skylan's audio racks for sale on a couple of different (free) sites, and have been absolutely inundated by interest. I own 2 rack models and 2 sets of speaker stands, one pair of which were configured in the mid-80's, and just so good, I've never been able to let them go - despite owning only planars for the past 6 years. (you never know when I might need those stands again!). They're a load to move around because they're full of silica sand - solid and dead as can be - not sure why you'd use anything else. Hats off to Noel and his excellent, simple products!
