My experience is different. Every speaker I've ever lived with sounded materially better when firmly coupled to a solid floor, including suspended wooden floors which is all I've ever had in my listening rooms. The most common difference I hear is increased definition and articulation in the mid-bass through lower midrange.
Most recently, I was suprise by the improvement in my Eidolons when I replaced the stock spikes with Walker Audio Valid Points. Given the mass of the Eidolons and given that they were already spiked, I wasn't expected a difference: but the difference was very material.
The key point is that all systems and floors are different; you'll never really know what you may be missing until you try it and then listen for yourself.
