Audio Supports

Why is it that the majority of audio equipment comes with four feet rather than just three? It seems that only having three would provide a more solid foundation that would better resist vibration and rocking. Speakers come to mind as a component that might really benefit if it was part of the original design.

Any thoughts? Are there companies that do this that I have not seen?

My Thor Cantantus Phono Preamp has three feet. BUT it is a rather large oval and it seems to me three feet work better of a circle or oval than a square.

The pros/cons are rooted in the real world of physics. Four beats three any day. Any working of a model of the physical forces in play will tell you that.

Since 3 spikes are better than 4 , would 2 be even better ?

The reason that three is better than four is that three points define a plane. This means that it's virtually impossible to have four points equally support something. This is why a stool with three legs won't rock but ones with four almost always do. If the legs can be adjusted then I'm sure that it's possible to set things up such that it really doesn't make a difference.

Nordost recommends putting three sort kones in specified locations under equipment and then moving the 4th around looking for the "low" point.
