OK, so the construction of the cabinet changes things. You could use one large MDF base if you use the Herbies under the components. Even though MDF is not great material for sonics, the Herbies would absorb vibration and and the MDF would not influence the sound.
Or use finished bamboo as the platform. It is dense and when used under components it provides neutral sonics. Use Google to find the right size of bamboo.
BTW, using glass as a platform does not produce neutral sonics.
