I've owned Osiris stands and Alantis Reference XL stands. I preferred the sonics of the Osiris, but to my knowledge they're no longer made and available only on the used market. I also liked the sonics of the Alantis Reverence XL, and preferred their appearance.
But, only two days ago I got a pair of Sound Anchor 3-post stands. My initial impression is that they're as good as the Osiris, maybe better. And they're built with the damping already in them... no need to fill with sand or lead. Take a look at their website, lots to choose from there.
Overall, though, I think that all of these stands are very good. FWIW, the other stands I like are the inexpensive 3-post stands that Parts Express sells. Put 'em together, fill the posts with sand, and you're set. They give a nice sound, but not the authority or the stability the other stands give, and they almost certainly should be used with spikes, which BTW are included in the package.
One more thing, if you can't use spikes/cones into the hardwood floor, you might consider using spikes/cones with metal pucks. Rubber feet likely won't give you the best sound. I also recommend that before you put damping material, like Blu-tack, between the speaker and the top of the stand, try cones, or small pieces of wood. I use 3 pieces of wood, each 1" x 1" x 3/16", under each speaker. Or you might compare the sound with that of Blu-tack, and then decide.
