I had a chance to try it....no change, really. The problem for me is that I have to use the isolation platform or I get a big howl going, and I think the new feet were designed so that you wouldn't need to use the platform. So for me it seemed a little overdamped. I've seen photos of people using the new feet with the isolation platform, so each to their own. I've also seen people not need an isolation platform at all, with the table very close to their speakers. So for me it must be a room thing.
Unless you're having some isolation issue, I wouldn't even bother. They won't make your table sound any better.
