Are Herbies isolation feet as effective as cones or roller bearings?
… A: When cones or bearings are performing well, they inhibit vibrations from reinforcing and amplifying themselves. Instead of acting as vibration barriers or absorbers, cones act as conduits to “drain” vibrations away. Components working well with rigid devices are basically in a state of vibrational equilibrium rather than being truly isolated and are dependent on the integrity of the shelf or platform they are used with. Particular “sonic signatures” are quite common. (The idea of draining vibration from a component into a rack which in turn supports other components is in itself a perplexity.) … Herbie’s isolation feet, by contrast, decouple and isolate components and work well with just about any kind of shelf or platform. In most systems, components perform closer to their best potential with Herbie’s isolation feet.
