Interesting idea about balancing the disc. However, in my experience, the tolerance at the hub allows the disc enough play that I would question the products ability to truely center anything.
I did feel that the edge treatment made a subtle improvement in sound but IMHO the engineering of this product does not support the asking price. YMMV
