I recently got a good deal on several sets of the classic, cone-shaped original Stillpoints with the five ceramic bearings, and presently have a total of 12 Stillpoints installed in my system.
The Stillpoints effect has been nothing short of amazing and transformative! Like others have reported, and I concur, you positively haven't really heard the potential of your system until you install Stillpoints under your components. Also, that Stillpoints have a cumulative effect --the more Stillpoints I have added, the more realistic sounding and involving my system has become. Now I understand why so many audiophiles float their whole systems on these marvelous little devices!
