Interesting discovery when my carpets were cleaned yesterday!


I have some bookshelf speakers that sitting on some Dynaudio Stand 20 speakers stands. They are each filled with 50lbs of lead shot and my speakers are attached using some blue tack stuff (it helps hold them in place kind of like mounting them with screws). 

Anyways, while having the carpets cleaned I removed the Dynaudio spikes that came with the stands so that the speakers would be easier to move around as a whole because they weight 110lbs-ish each. 
When the carpet guy was done we put the speakers stands on some foam blocks to keeps them off the wet carpet until it dried. 
Later that night after getting the speakers dialed back in (I have certain measurements to get them back to where they were), I kept the foam blocks on the stands until I know they were right. 
Well, it actually sounds better with the foam blocks than the spikes. So now I’m on the hunt for something to actually use instead of the spikes. 
My room is carpeted  with carpet padding underneath on a second floor (a wood sub floor). So I need the ability to lock them down so they won’t get knocked over as I have a five year old. 
I’m not sure which type of feet I should use. Should I isolate or what what?
I don’t think I’d spend tons of money on something like this but I want to see what you guys would say. I’ve looked at the Gaia II feet and although they seem to come recommend I would prefer not to see them being silver in color...don’t know. 
Ideas?

I wouldn't jump to the conclusion that decoupling the speakers led to your experience of better sound it might have been the height from being on the foam carpet pads. Maybe they sound better because they are aligned better with your ears at the higher position. Just a thought. 
What no one has asked thus far is in what way do they sound "better" to you? Ppl might have a better clue in their recommendations. 
I have the Gaia II's on my Spatial M'3 Sapphires on a hard wood floor.
They are very open and dynamic sounding especially in the bass and lower midrange. They were a huge improvement to just spikes or the rubber feet. On carpeted floors I would imagine spikes would be the way to go as they connect with the hardwood floor underneath your carpeting. My Vandersteen's were spiked to the carpeting and also were greatly improved in the bass and dynamics as well.
i say olde chaps have you heard of terrestrial coupling - the ultimate sink? what i done is buy a plot over a zone literally dotted with fracking sites. i then put be mighty JB-Ell 305s over meters and meters of cement and tubes (not pipes, there is money to think aboot) and connected my drivers with the very core of our earth. i use methane to run the generators. Motorhead never sounded so good.
