We have been looking at an alternative to magnetic levitation for HiFi isolation. Our aim is to give a wider load range and more stability under tall or heavy speakers. The feet have a variety of cool materials. A carbon fibre main body with ebony and brass centre, suspended on a braided nylon web. Our testing has been giving exciting results with string theory feet performing to a very high level and doing just what we hoped.
Under speakers they were really very exciting, with comments like “where did the speakers go?” and “It’s just a wall of sound!”. We are now working on a Speaker suspension bridge with these feet. It also gives an option for those who are suspicious of magnetic fields. Take look here.
