Yeah, pretty impressive stuff. Try the Cartridge Enabler, and if you do be very careful to use only very slight tightening torque. I learned by experimentation. Try loosening very slightly, like 1/6 of a turn at a time, listen, repeat. Depending on your cart, headshell, washers, etc it might not make a huge difference. Then again it might. Someone paid $200 for a micro torque wrench to do this and some people swear by them. Or you can go by feel and listen, same result. Anyway this is real good way of learning super tight is not always better.
My understanding is the Enabler and Mat are the same material, engineered to facilitate directional vibration control. The Enabler for example is marked Top even though it looks like conventional material that could go either way. More here than meets the eye.
