Hi Swanand,
The system should not lose any color but I would think placing the pucks and cones on top of another isolation platform should help. Try a nice wooden platform anchored to the floor (if on carpet- use psikes- on hardwood use spikes and couplers). Then place the combination of BDR pucks and cones on top before resting the speakers on this configuration. Currently I am using TAOC Tite pins (Japanese made cast iron isolators) under the speakers and the sound is very precise without sounding clinical, bland or even bright. Putting granite slabs would brighten the sound- which is not something you would like to do with ML speakers since they tend to fall that way of the spectrum. Instead, getting nice wooden boards (a combination of maple and mahagony or pine) will help give the speakers a richer sound without losing any of the detail.
