When I had an Aesthetix Calipso Audioquest Sorbogel "Big Feet" worked the best in combination with the rack system (bad) I was using. I tried Mapleshade Heavyfeet(to bright), BDR #3 & #4 cones good but there were still vibrations (hash). A Calypso owner with a Salamander Synergy rack used AQ Big Feet in front and maple blocks in back until he tried a SRA platform that he felt outperformed all prior tweeks. Grand Prix Audio uses Sorbothane pads between the rack and shelf, Project TT's have sorbothane pads in the feet! I only use sorbothane under my EP15A's and Direct TV DVR presently.
