As for me, I do think footers can make a difference to sonics, especially as regards turntables, maybe not so much as regards something like an SDS, but I am just wondering specifically about the Terrastones. For example, there are dozens of variations on the original "tiptoe"; why would any one of them "sound" different from any other of them? Materials used in construction might make one different from another, but I would have to hear it to believe it. I gather that the Terrastone is not a conical type footer. (Guess I should Google the item.)
