I have never heard any spike, expensive or inexpensive, whatever materials, perform as well under loudspeakers as well tuned springs.
I have Smalleys wave springs that cost me something like $25 , they sit between my 92lb stand mount speakers and approx 90lb stands which are now (not always) on conical shaped steel spikes.
If I ever hear spikes produce as clean a sound as springs, rest assured I'll man up and declare whatever truth I can hear.
I am sorry you have not heard it, experienced it, however it's a very cost effective vibration control device, used in all transportation sectors under vehicles for that very purpose.
The concept simplified, is that if an object is moving relative to your position, the sound emanating from it will have variations of pitch. One very notable sounds is that of a formula one race car, as it approaches, passes and leaves, has a distinct sounding change of pitch.
Allowing the enclosure to expand inwardly and outwardly whilst maintaining it's position relative to center of gravity, the smearing is lessened, or removed.
Done correctly, sprung isolation is very effective, and highly audible.
I hope perkris opinion is based upon favorable personal experience, which has been repeated by many others. Other Agoners who have used both, have shared that Star Sound are an effective technology as well.
