The footers reviewed here are a spin-off category from the footers developed for their racks. I’ve championed this category for years, going back more than two decades to the first reviews of Stillpoints, Boston Audio Design, and Soundeck (then known as Sound Damped Steel). And I have a shoebox full of others, comprising various elastic materials, wood, ceramic, and steel balls, and concave retaining fixtures.
