Solidity and mass aren't always the answer. Sometimes a lighter frame with low mass and no bottom plate is the better approach, as in the expensive aftermarket wooden stands that are sold for Harbeth Monitor 40's. The name escapes me right now.
I recall in the '80's I bought a pair of Celestion SL6s speakers, and I bought a pair of inexpensive Chicago speaker stands for them because that was all that I could afford. They had a thin top plate and four skinny tubular legs; one at each corner. The speakers performed fabulously on those stands, but sadly I didn't realize it until I had some more money to spend on heavy steel stands with massive steel posts filled with lead shot. The magic was gone.
I also had ProAc Response 1's that loved a massive stand. Spendor SP100's also responded differently to single or multi pillar stands. What I am trying to say is that expensive isn't always better, but sometimes it's justified if a talented designer has done research on your particular speaker and come up with a design that brings out the best in that design.
