Depending upon your room, floor coverings, seating position and perception, I am willing to entertain the notion that it is possible to hear a difference between "nothing" and the spikes or feet simply due to the difference in height of the tweeters. I doubt *I* could hear it, though.

I like using the spikes because it keeps the kids and the dog from repositioning my meticulously calculated toe-in angles.
