The feet that come with most products are generic, extremely cheap and often poor quality items. 
  Many Hi-Fi companies and designers, either through ignorance concerning the importance of correct 
  vibration isolation or simply a cost cutting exercise, neglect this vital issue. Sadly, many audiophiles
  are willing to accept the misguided and ultimately very expensive advice of an ill-informed shop assistant.
  They upgrade unnecessarily their entire systems or spend huge sums of money on cables, connectors 
  and other accessories, when in reality the problem is poor hi-fi component isolation.
