Like you, I want to protect my hardwood floors. I am using cutting boards (with felt feet under them) to anchor my Soliloquy 5.3s. Investment is about $30.00. Works fine for me . . .
I also used to have a Billy Bags rack with the spikes, and I used the Quadrasphere Protective Feet to which I added felt pads. Very secure, and the rack wasn't terribly difficult to move around either.
