We compared the existing rubber and spring feet on various turntables. Our newly designed feet largely replace the qualities of these two. these feet offer exceptional vibration resistance. Reducing vibration by 94.7%, they are a gel-like, shock-absorbing material that retains its shape under pressure and have been used by to isolate vibrations in their equipment. They are also used to isolate subwoofers and turntables. Our newly designed feet can also improve the performance of many hi-fi splitters, A/V components, and other sensitive equipment by reducing unwanted vibrations and resonances. Using them provides an effective solution for maximizing the performance of your equipment. Our newly designed feet are specially engineered to provide optimal performance, secure equipment retention, and vibration absorption, isolation, and damping properties.
