Hey guys, i just moved into a new apartment, and drat, the room i intend to place the hifi has a fairly noisy wooden floor!!!
now my bookshelves are on wood stands as well, (i got the local carpenter to do two solid wood stands) and i have two slabs of granite around 3/4 inch thick on top of the stands, between the stands and speakers.

So my question is, what should go between the stands and the wood floor? I was thinking some cork pads as these stands dont have spikes!! Or another thinner layer of granite? I am still a bit confused about 'decoupling' and 'coupling' from the floor, and i know there isnt any perfect theory, but would appreciate some guidelines please.
thanks alot in advance
