Weights on top of equipment to dampen vibration

I have a heavy Stillpoints record weight on my Roku.  Incredible!

My experience with the VPI bricks was they squashed the sound. I do use either heavy wood or  thick marble. YMMV

                                          SO MANY variables!

Variables make things mysterious, and who doesn't love a good mystery?

Being a very old timer, and remembering the VPI Magic Bricks, these were long before vibration control under the chassis was thought of. My how times have changed. Recently I placed VeraFi Audio's Very Black Hole vibration devices under my kit, starting with under my Audiolab 6000 CDT transport. I can't imagine how a set of these can perform such magic for a reasonable $199/4. Following that, I now have them under the rest of my kit. I posted a review for further explanation
