Consider how much more complex this approach is than the following standard, rather simplistic, calculations that solve for only noise reduction:

The reason balanced energy transfer is crucial is because of 2 fundamentals that are often ignored. You can overdamp a component. Overdamping results in a loss of depth, detail, slam, presence, pace and so on. Dull and lifeless systems sound like big, expensive, hifi radios. On the other hand, components can be underdamped. Underdamping results in annoying, unnatural brittle edges in the presentation which cause listener fatigue. And, worst of all, both abnormal conditions can occur in systems at the same time. There is nothing worse than a flat, hifi soundstage with glaring edges in the vocals and instrumentation.
The abnormal conditions noted in the previous paragraph occur in audio systems because damping devices are allowing an unbalanced energy condition to persist in the components. Anomalies can be heard in the least to the most expensive audio systems. To make a point, no amount of room treatment, conditioning or signal shaping can fix constant thermodynamic anomalies occurring inside a chain of component chassis. You fix signal corruption occurring inside an otherwise pristine signal path by overcoming its exact cause.
Remember that vibration is everywhere in the listening room and it cannot be stopped. To produce reality in a stereo system, the damping system under the component must be designed to maintain the perfect balance of push and pull energy transfer. Zero vibration transfer (the firewall and diode approach) is not the answer because fake firewalls and diodes cause vibration to store up in the component. The objective is to manage the transfer of energy into and out of the component (push/pull) to get the full performance potential of the component.
