For placing an amp and a CD player inside a built in cabinet, what would be the best way to control vibrations: do I want some kind of isolation platform (actual brand suggestions would be appreciated), or something more like Herbie's Tenderfeet? Or both?
If it were me I would use a maple platform with cones to transmit vibration from equipment and use dampeners between platform and cabinet shelf to prevent cabinet/floor vibration from entering equipment.
Ya, and since springs isolate vertically very well, but laterally not-so-well, a set of roller bearing somewhere. I prefer them directly under the component where possible. So, the component, the roller bearings, the maple platform, the springs. Roller bearings provide no lateral isolation, acting as a coupler in that plane, transferring energy just as do cones, if you believe in that sort of thing ;-).
I second the roller bearing idea. The concave shape of the base is a very shallow angle so there is some isolation horizontally I think. They also are good in the twist and the other two rotational directions due to the concave shape of the roller bearing bases. Can’t recall if I mentioned it already but Super Balls on Snaple bottle caps is a faux roller bearings for those DIYers out there.
