"What are the measurable physical properties of lead that could support the contention that it is superior....."
Weight, density, damping coefficient? We're talking about the transmission of vibrations through a material(s), and this stuff isn't exactly unknown.
If you affect the torque to weight ratio of an existing motor system, then you might screw up performance? That rates a duh.
Lead doesn't hold shape and is normally used between pieces of more rigid material. It's extremely affective at killing vibrations. If the idea is to match the record impedance with the material directly under it, then lead is a good choice as sandwich material.
Perhaps Trans Fi type spikes is a better choice? I think Naim Audio has a similar scheme. I've never used them.
