Silica (quartz) sand, as used in sandblasting, is what used to be recommended. The only drawback is that the dust coming off of it is unhealthy - so fill items outside and wear a mask. Once contained in a rack or stand it is no longer a health hazard. If stored inside a lumber yard building it should already be dry (avoid sand stored outside on pallets). Lead shot is difficult to dispose of properly, fortunately my auto mechanic accepted it for recycling.

@incorrigable your idea may work the best for me!

The Star Sound people used to sell something they called Micro Bearing Conductive Steel. Star Sound used it to damp their Sistrum Stands and their cables, and they sold it in plastic jugs for damping audio racks. I used it in DIY cables and still have a small jug of it. It is no longer sold but it probably the same as, or very similar to, the steel shot for blasting discussed by @jsd52756. Maybe like this (link). |
FWIW, the Star Sound people (Sistrum stands/racks and Audiopoint brass footers) are still around under the name Live Vibe Audio, LLC in Delaware, USA (link). I did not see the steel micro bearing material listed for sale in their products but they discuss using it as fill for the legs of their Rhythm Platforms (link). The presumed benefit of using their micro bearing material is discussed in this product description (link) under the heading “Setup”. |
