I know well that this subject can render in hot debate. But if we put the emotional aspects aside, and just focus on experiences and physics, I want to report on my findings.
The findings are all about what I hear, not about anything measured. I have not measured anything, at least nothing that can be presented in figures.So, my setup consists of 3.7i and a single DWM.
The 3.7s have the factory metal feet, the DWM has the factory oval MDF foot.
The floor is board on wooden frame with wall-to-wall carpet.I have had the speakers feet put directly on the carpet until now, when I decided to place soft-pucks under the feet. The puck-brand is "Sonic Design" and the pucks are named "SD". These are just simple cut-outs from a foam-sheet and they come in different diameters, all (I think) of the same thickness. The foam is not prone to permanent deformation, i.e. when the load is gone the original height is not changed.
So, the most interesting thing is what they do whith the sound. Or rather with the music.
My observations of OBVIOUS i.e. not minute changes:
Deeper bass
More articulate bass
Greater depth of music (I listen mainly to large scale orchestral music)
Clearer, mid- and high frequenciesThese pucks are cheap. Maybe not exactly cheap regarding the material and production, but cheap both compared to the metal-frame-constructions sold, and in relation to what they do to the music.
Take the above as a pure report, not as any attempt to convince others of what to think. You may think whatever you want. And of course also explain your thinking and experiences in this tread.

I have the Sonic Design puck, too, and I immediately noticed bass improvement.
I'ts was unexpected because I bought them to decouple my Quad ESL-988s from the floor as the neighbour's wife was complaining about me playing too loud.
She stopped complaining and I got better bass. Win-win!

I just swapped the points and pads on my Mye stands (my Mye, hey hey... Couldn't resist. And Neil and Grant are both Canadian!) for Herbies Audio Lab threaded stud gliders. Not only did I get improvements similar to what you mentioned, it's easier to play with the speaker position. My floor is also carpet over a wood subfloor.

I replaced the spikes and cones on my big ProAcs monitor stands that sit on a raised wood floor years ago with Herbie's Threaded Stud Gliders. My results are exactly as you described.
My LRS are still on the stock slats, but do not excite the room too much. They are rolled off before the amp at 70Hz.

Stroemberg, we from Sweden have known this about soft feet for 30 years now.
Some of us, not all.
Can't argue with results.
It seems to me that decoupling + high mass is ideal, assuming the floor reflections have been captured already in the recording. If the mass of the speakers is low, then they need the mass of the building (and the planet) to keep them from moving opposite the diaphragm.
Another thing -- those stands that make the baffle more rigid actually do work. They are coupled to the floor, though.
I remember somebody floating a massive rock or something and putting their speaker on it.
I put my Rythmik open-baffle subs on these anti-vibration pads and there is tauter deep bass and less excitation of room modes... plus happier downstairs neighbors :-)https://www.amazon.com/LBG-Products-Anti-Vibration-Conditioner-Compressors/dp/B07PVF8GHF
Seems to me like now I am driving the air and not the floor....

How do one explain the effects on room modes?
