Out on the tiles...with speaker spikes.

If you've got the patience and access to the right equipment (I do!), you can cut aluminum round stock to the thickness you require, then countersink (a standard drill bit will work just as well) to the depth you want. The aluminum is soft, and easy to work with. Probably less abusive on your tile than a coin would be also. Then go to Home Depot or Lowe's, and purchase some felt dots to stick underneath. Although I much prefer the acoustics of a dead floor-- Carpet, with a heavy pad beneath.

Apc-d coupling discs from Starsound will give you the most improvement in sound. Lak is correct these work perfectly on all types of wood or stone products and they are an extension of The Audiopoint so they do improve energy transfer.. Its a combination of material [ brass ] and the geometric ratio by design..

I second TWL's motion for coins or hockey pucks. No need to spend a lot on tweaky stuff. One friend bought round lamp finials made of chrome plated steel. The tips of the spikes dropped into the threaded hole and the overall effect was to protect the floor with a distinctly high tech look.

I used a spade bit to cut a depression into the middle of a hockey puck, and dropped the cone-point's floor disc into that, so that it was flush with the top of the puck. That gives you a little more lift, and makes the floor disc a larger target, so it is much easier to position under very heavy speakers. Looks fine and works great.
