can be OK is you ground the legs. It would be easy to do just add another nut so that you can fasten a ground wire. In my steel racks, I found that I had to ground both top and bottom of the rack as the steel has relatively high resistance and the there is a slight voltage potential between the top and bottom of the legs ( my racks are five feet tall).In discussing this issue with the folks at Sound Anchors they added a ground screw to their racks. In fact when the Townshend Seismic sinks were available I would add a ground screw to the sinks, too, with an improvement in the top end clarity.
As a simple experiment, try changing the mounting screws on your speakers to either brass or stainless steel. The increase in performance is very noticeable there. Brass is better because the higher copper content is electrically lower in resistance, but both, being non magnetic ( use the non magnetic stainless!) are an improvement over black iron (regular steel screws). Check on line if the appearance bothers you: black anodized stainless screws are available.
StuPS. another great place for changing hardware is the center bolt on toroidal power transformers. I use non conductive material there, like nylon bolts (available at marine hardware suppliers). Again the difference is noticeable: sweeter and the midrange and upper frequencies become clearer.
Of course YMMV. Those who have never tried it will never know.....
