Here's where I will be getting my lead- www.welcocastings.com.(a Canadian lead manufacturer/distributor- they will ship around the world) I am actually going to do the ultimate- a 'hot lead pour' into my speaker stands. Welco can do this, they actually mix 3% antimony (an impurity) into the hot lead- the antimony helps avoid shrinkage from a lead-only pour. I can't even imagine how heavy the stands will be after that!! Sounds like a rather exotic solution, but hey, why not?- you just can't beat lead for resonance dampening- good luck! Oh- btw- Welco also sells individual pieces of lead- I am going to pick up a couple of their 'diving weights' (lead with a rubber coating) for use on top of an outboard power supply, with Isobearings under the power supply- it works!!
