Best way to couple monitor speakers to stands?


I made some Sound Anchor copy 4 post stands for my Revel M20 monitors. They are very heavy and I think the sound is noticeably better than the stands I was using before. I am using 4 dabs of blue tack to couple the speakers to the stands. I wondering if big improvements can be made with something else. The top of the stands are 3/4" thick by 2" steel bar roughly the same size of the speaker and then at each corner a 2x2 steel tube runs down to a bass. Looks just like the sound anchor 4 post stands. I filled everything with sand/lead shot.

Is blue tack good enough?

Herbies Big Fat Black Dots are an excellent interface material. I use them between the lower and upper modules of my VSA VR4JR speakers with a significant improvement in clarity and dynamics and use them also for my monitors on stands. They come with a money back guarantee But I'd guess you won't part with them once you give them a try.
A very inexpensive alternative is to use V-Pads available from heating and air conditioning suppliers for about $3 @and are identical to Mapleshade IsoBlocks.
I found each of these approaches vastly superior to blue tack.

The M20s have threaded holes in the bottom. When I owned the M20s I mounted them to my Sound Anchor stands via a plate I made with holes drilled to match the M20 mounting holes. I had to drill counter sunk holes in the plates to match the stands mounting holes. Once complete the speakers were firmly coupled.
The next question is, was the sound improved?
I guess I mean whatever sounds best. It's nice that the blue tack sort of glues the speakers to the stands so if they did get bumped they wouldn't come off, but what I'm looking for is whatever sounds best. I suppose acoustically couple the speakers is what I'm looking for.
