I bought a pair of Osiris Giza multi-purpose stands that I used to some effect in a previous setup (same folks that made the acclaimed 24" speaker stands). They weigh a ton and, when filled with sand, require two people to postion them without causing damage to something in the process! They have adjustable cones at the four corners with optional feet. Standing about 3 1/4" tall, they can be perfect for some applications. I use one now for an amp stand and am keeping the other for when I finally get around to biamping. See if you can find a pair if you wanna raise your floorstanders.
