If the spikes are adjustable tilt the front of the stands up a fraction of an inch. A minute rise (@ the front of the stands) makes a big difference in the firing angle @ 8-12 feet away.
Material, like Paul suggests, (not the roller blades:-) might work well with his Harbeths as the cabinets are designed to resonate within a certain frequency range (you want them to vibrate as they are tuned this way).
I suspect that this might also be true of the Coincident Triumphs as the ones I tried sounded best on cheap/flimsy stands (not heavy/rigid ones).
