I use some form of vibration control or tuning under just about every piece of equipment. ( Many times people use the term "vibration control" when the item in question actually just varies resonant frequencies.) As Roxy54 says, they all sound different. Plus, every piece of equipment is different as far as how much vibration control or tuning affects it. My Marantz Sa11S1 is greatly improved by the Boston Audio xl tuneblocks I use, but they make only a slight improvement under my other gear. I also use three maple plinths, one under my turntable, phono stage gain stage, and phono stage power section.
