equipment on cones

i see many people place amps, cd players and dacs on 3 cones instead of the original feet. they usually set 1 in the mid-front and 2 in the back.
i have experimented with different equipment, and only about half of the time the outcome was better. using other feet/cones than the original is usually better, but not always in the most common 3 cone placement. sometimes it was way better just the other way around, 1 in the back and 2 in the front. But i found the best way that will work most of the time is to use 4 conesjust on the inside of the original feet.
what inside the equipment do one have to think about when placing cones under it? are there any rules? other than the obvious,- place them where it sounds best..

Assuming that everything you said above is correct (and I'm NOT in a position to judge that--too ignorant), then the above post is the single most comprehensive, yet concise and well-written explanation of vibration effects and their solutions in home audio that I've ever seen. Thanks.

Thanks hoover. BTW, there is one device I know of that combines the properties of removal (cones) and absorbtion(rubber) and that is Stillpoints. But they're pretty expensive.

I've heard the same thing about them. Only one other person has been sufficiently astute to point out their dual functionality, which I'm pretty sure isn't even discussed on their own website. They discuss the calyces only, I think. Anyway, I have four sets of three, all deployed under my loudspeakers and their stands. I talked about their effect briefly in my review of the Intuitive Design Summit PSL 624 Loudspeakers.
And, you're welcome, for what it's worth coming from someone like me--an admitted resident resonance ignoramus.
