I hope an engineer can chime in here, but I'll take a shot at this. A rack really will only deal with vibrations that come through the floor. These are traveling through concrete or wood, and are low frequency. I personally do not see how any rack could effectively reduce air-borne vibrations which are much more brief and of higher frequency.
The active platform will automatically level the platform, and adjust for the center of gravity at the beginning. Sensors will continually monitor the motion to mathematically model the vibrations. It will then create a counter-reaction to bring the platform to rest. Based upon some graphs on the website, it appears that the system will react as soon as the first wave hits, and can settle the platform within a few tenths of a second. This is in contrast to a passive system where the vibration would continue for over a second before coming to rest. All of this depends upon very responsive sensors which are continuously modeling the behavior of the platform in all directions. The concept of halting a resonance in a single direction seems easy to grasp, but it's quite amazing that this can be integrated in 6 different directions with relative speed.
Self-induced vibrations should be effectively controlled as well. This should include spinning platters and humming transformers. Anything that alters the center of gravity or the absolute weight, such as moving the component or opening the drawer, would require the equipment to take a second to automatically relevel and compensate.
The website has some technical papers and graphs that will give an idea of the speed and frequencies involved.
