Seeking advice on vibration control for a Hydra

I was moving my equipment around this weekend and moved my Hydra to a new location and used ebony cones to support the Hydra. The music was not involving, I wasn't taping my toe like I used to. I worked backwards and realized I changed the cones, put the brass cones back in place and all was well again. The difference was pretty major. I am wondering if others hear such a difference with the Hydra and what has been most effective support devices you have tried.
