Hi Cyrus & Lhobby,
I had some other speakers prior to the 101's and had placed the speakers onto Sistrum SP-1 platforms after doing some research and I was really impressed overall with the improvements being all positive. I use these specific platforms because they are allot easier to work with and fit nicely underneath the speakers, I can still pivot the speaker easily so to reposition with them still being on the platforms, if they were placed on the SP-101's you would not be able to do this, well maybe you might be able to but it would be allot harder. I also have a pair of SP-101's but use them under my mono blocks, just unbelievable results, very happy.
They sit ontop of very thick carpet & under-pad which is on top of double 3/4 plywood laminated together and secured to resilient floor joists. If you have flooring that you don't want to get damaged you can use the protective coupling disc's. I use these under my amps with the SP-101 so not to damage them. One person whom I assisted placing his BIG JM-LAB Nova BE speakers onto SP-101's, he lives in a Condo with concrete floors and was absolutely stunned. He obviously knows his system better then me but with my limited listening prior and after installation I noticed right away bass, clarity and more focused stage and I was off to the side, it was so obvious. His wife came home while I was still there and committed right away saying what ever you did it sounds better than ever. Thumbs up!
So when I got my MBL's I just automatically put them ontop, well it was time to take the MBL's off platforms some 12 months later to see. Well all I can say is they are back on the platforms, it's a no brainer.
All I can say is they really work well and every person whom I have recommended and has tried was thrilled.
