I use Vibrapods with terrific success. Decoupling is best in my view if you like to preserve all the energy of the music.

I'm drawing a blank on the name but there is a spike that has floor protector built in. Not attached but it moves with the spike if you pick it up. They advertise in Sterophile...
Oh here, I think this is them
I hated having spikes on my speakes on a wood floor, major production to move them.
Better results will be had if you treat the equipment that resides in the rack first and keep the rack coupled to the floor using the spikes. Just make sure that the rack's spikes have the weight equally distribed thus avoiding any wobbling etc. Also, if you can position your stand as to have the feet as close to the floor joist as possible, the better.
For speakers, I have tried both coupling (with rigid materials) and decoupling (with viscoelastic materials). In my system, the results of coupling were significantly better than decoupling. Decoupling gave a "softer" presentation, so that it concealed low level detail and obscured transients.
Of course, an advantage of decoupling is that it minimizes the potential resonances between speakers and floors. But filling your stands with sand/lead shot should hopefully provide enough internal damping to minimize potential resonances, without the need for decoupling.
I have found that this approach of coupling + internal damping yields the best results in my system, where I have a pair of bookshelf speakers resting directly on top of a piece of furniture (not ideal, I know). In my system, I achieve coupling + internal damping with a combination of Outriggers and Black Diamond Racing cones and pits. The Outriggers and BDR cones/pits are very rigid, so they provide coupling. The BDR cones/pits are made from carbon fiber, so they provide internal damping. In your case, you could use BDR cones/pits under you stands. The cones are threaded, so they may work easily with your stands.
BTW, I am not questioning anyone else's results. These were just my experiences in my own system. YMMV.
