It depends what your floor is made of. If it's concrete then maple platforms might bring some improvement to the sound. I have the Mapleshade platforms, on concrete floor, and they do very well. But using them without spikes wouldn't make so much sense, I imagine, because you'd lose the coupling to the floor.
One way to prevent damaging woodfloors because of spikes is to place Yamamoto PB-10 footers under the spikes. They're imported by Venus Hi-Fi, and you'll find a review of them on 6-moon.
