Proper control of vibration in hifi is critical. Many electric parts are microphonic, so controlling vibrational noise in electronics chassis keep the tubes, capacitors, yadda yadda, from singing along with the music. In the case of digital componentry, it's less clear-cut, but in a laser-based reader, reducing vibrations keeps the read clean and uses less error-correction, not to mention, it still has capacitors! Clocks may have some issues to be addressed on this front, many people have reported good results from damping their clocks in digital gear.)
Overpriced maybe, but easy to experiment on your own with various supports, dampeners, yadda yadda
