Hvu, It is extremely stable with three footers under a component case, and Herbie's or Cardas/Ayre footers can bear great weight and still provide desired vibration control.
You place two of the footers under the heavy side of your component, and a single footer under the lighter side, if there is a big difference in distribution of weight to be supported.
If each Herbie's Tenderfoot is not tall enough when you do not remove the original factory feet then you can simply place a Myrtle Wood Block footer beneath each Herbie's Tenderfoot.
You will be surprised how you can make subtle adjustments in how your CX-7e sounds when you use different footers alone, or in combination. These are all very reasonable in price.
