Timbernation uses butcher block for their racks and they work just fine. If your speakers aren't that heavy, I'd go for something as thin as 1" with some of those cork footers or something from Herbies Audio Lab between the floor and the maple block and spikes for the speaker.
Whatever you use between the floor and maple block doesn't have to be that big or thick at all: just enough to provide separation. That way, balance is more secure and you end up getting two types of isolation without raising your speakers too high.
All the best,
Nonoise
