I have both vibrapods and Isonodes, I prefer the Isonodes. I just feel they do a better job, acting like sponges to obsorb vibrations. I have them under the glass platform supporting my Sunfire Theater Grand 3 processor and I like the way their squishyness flattens out like the rubber grommet on a shock absorber. Isonodes also won`t leave marks on your rack shelves like Vibrapods will. Regards, Robin
