I have lived with hard wood flooring for 28 years with horns, ribbons, electrostatics, including the original Quads, big dynamic drivers in the BMC Arcadia speakers, and monitor speakers. Everything up front is on Star Sound Audio Points or their Rhythm platforms and racks. I am on a persian rug that runs from about a foot in front of the speakers to about a foot behind me and about four or five feet to my left and right. Finally, I have a set of Zilplex resonators in the room. The latter are the eight room treatments that I've tried.
One thing that I have definitely learned is that no cables should have contact with the floor and that a ceramic isolator is the necessary standoff.
Another is that I could get no bass out of the Quads nor could I find any subwoofer that worked well with them. I first heard Quads in 1962 and was shocked with what I heard. In the early 1970s, I had double Quads in a rack. They gave me much more satisfaction.
In short I don't think your hard wood floors are your biggest problem. A thick rug would probably help. I don't know about having Quads on rugs. I put my double Quads up on points on a concrete floor. I think they greatly benefitted from isolation on points.
