The simple answer to your question is YES. Different components react differently, in my experience, but this is more to do with the quality and type of the construction of the component than with anything else. All seem to benefit from a supporting structure that is light, rigid and damped. Some people have preferred heavy and damped supports, but my experience is that this is usually a preference for the damping that is easily achieved with a heavy support, over the superior pacing (or PRAT) of a lighter support. Up until the day I tried a shelf that was truly light, rigid and damped, I had experienced difficulties with light supports because of peaky resonances. Now I know the ideal combo is achievable I stick with the light/rigid/damped approach.
In any case Marakanetz, I don't believe that one's enjoyment of this hobby is enhanced by trying to deduce what will be musically beneficial from one's understanding of general physics principals, and that you are best to retain a more open mind that there are influences and trade-offs that are not immediately obvious, and therefore mix your scientific musings with a healthy dose of "suck it and see".
I can attest, from experience, to the fact that good vibration isolation should be considered for all of your components, including power conditioners.
