has lead shot surpassed cold

I will assume that you meant gold. And yes, that is incredible.

Are you talking about Speakers or Speaker Stands? If you have to have lead, McMaster-Carr has it for $528.00 for 50 Kilos plus shipping.

Might I suggest that you use sand to fill your stands, and Blu-Tak your speakers to the stands. I sincerely doubt that you will notice any audible differences but you will markedly decrease your potential for environmental toxicity.

Last time I purchased lead for my speaker was in 2005 and I paid $20. for 25 lbs. It is difficult to believe that the cost has gone up so much.
