The best I have heard is the Symposium Rollerblocks and Ultra Shelf. check out symposiumusa.com
Amazing stuff that is easy to point to when you do an A/B with the shel in and with the shelf out. I dare anyone else to do a similair test with their favorite isolation product. I nailed the symposium difference every time. The stuff is expensive but its the best in my mind. I have and do own Vibrapods, DH COnes (Jumbo and Large and Medium) and DH squares. Thes cheapes result that added the most improvemt was a DIY sand box. MDF box with sand inside. Easy to make even for somebody like me. I urge you to try out Symposium. It works especially well under anything tube and front end gear. I have stopped fooling around with cheap tweaks that get me almost there and now know that Symposium is where I want to be. Maybe it will work for you as well. Happy listening
