The Perfect Isolation Feet for Source Components You may not be getting the full performance potential from your source components if you're not isolating them from room vibrations. Pangea Audio Pico Feet are made specifically for source components like CD players, Blu-ray players, tuners, phono stages, and line level preamps. They also work beautifully with DACs and other digital gear. Pangea feet help keep the muddying effects of vibration out of your signal chain, letting you enjoy cleaner, purer audio and video. Sorbothane Visco-elastic Polymer Audiophiles around the world recognize Sorbothane as the leading material for absorbing and cancelling vibrations that can adversely affect audio and video performance. Sorbothane is a visco-elastic polymer. Although it's a solid, it behaves like a liquid in relationship to vibrations. Vibrations excite the loose bonds between the Sorbothane molecules, causing them to rub against each other and change the vibration energy into quickly dissipated heat energy.
