Hello,
I used to be a carpet cleaner so this spiked my attention. One thing that came to mind is the blocks changed the height of your speaker which changed the height of your speaker to your ear. Sometimes even a fraction of an inch can make all the difference. It could be the decoupling too and/ or both. Be careful about dropping money on something that might be fixed with a blue foam block which do hold more weight than the traditional white styrofoam blocks. Try putting a coaster under each spike and see if that does the trick. Also put an older copper penny under each spike. What are you out .08 cents? I hope you get it sorted out. Now I am going to try the foam block test.
