Placing Tenderfoot isolation feet under the components would likely do very well. You don't want to lift these components much or you'll lose some of the acoustic aspect of the bass development. With the little speakers in these units, that would probably be considerable.
The Meridian units are sort of like cats and chickens in the same cage. Rack components like CD player, preamp, and amp usually do best with Tenderfoot isolation feet. Speakers are a different animal altogether when it comes to isolation--Fat Dots made with dBNeutralizer are virtually always best for speaker isolation. Adding a grungebuster Dot to the Fat Dot will achieve a hybrid that should address all aspects of these components very well. Dots can of course be placed alongside the stock footers if they are tall enough to lift the component free of the stock feet and if there is enough room.
If you should already have some Tenderfeet, I suggest giving them an audition under the Meridian units. The only way to know for sure how they would work with your components would be to give them a try. Otherwise, I recommend giving the Dots a try.
