Tile floor! Help!

So normally I use the threaded spikes that screw up into the base of my Dynaudio Contour 3.0's when they are on carpet/concrete. I don't like using them directly on this new tile floor that my listening room is now residing. The tiles are a little rough not super smooth so I have to level the speakers and get them anchored properly, when I use a small amount of putty in each corner it kills the life of the sound, so out with that idea, then I tried some little clear rubber discs and that was a lot better but I'm still thinking the speakers are not quite right, Ive never had to deal with a bare tile floor ....what do you all think would work best under these speakers?
