Lots of manufacturers, dealers and audiophiles talk about the perfect platter-LP impedance match. In the cases I cared to research - like AMG, Basis, SOTA et al - some seem to be converging on a vinyl-to-vinyl solution of one kind or another, or PVC-to-vinyl, or some other form of plastic, resin or other. The new Basis super platter, for example, touts its some-sort-of-vinyl-based layer on top of the platter.
I am building my own impedance matching solution, which so far partly depends on a thin layer of Isodamp - another highly damped vinyl, possibly coupled with Spec's AP-UD1 (still in evaluation phase) - and it appears to have hit the nail on the head, with excellent damping, evidenced by the tightening of the bass with exceptional reduction in overhang, increase in leading edge attack and clarity, smoothness of choral works, and obviously, a reduction in mechanical noise... among many other improvements (I may post the final solution under my system thread one day).
So I was curious what others know about this subject, and how do you approach this type of mechanical impedance matching.
