Weights on top of equipment to dampen vibration

I use the KISS theory
Normal 15lb dumbells on top of each transformer ..works for me

interesting Tvad Where did you get the brass weights from ?

Important to note the weight doesn't sit directly on top of the transformer I have a blue circle puc in between the two surfaces

I checked Palmetto audio for the carbon blocks it doesn't look like they carrry these any longer.

I still have a couple of VPI magic bricks. They are very well made, and look kind of sexy. I remember when they came out, a buddy and I were trying to tell by AB comparisons whether they made any difference. We decided it was important to be able to see them on the equipment in order to get the full effect. (But that was in the dark ages of the 80's; equipment is much more sensitive now.)

We developed on our own "magic towels," thereafter. You covered the top 1/3 of your dynamic speakers with them whenever the speakers seemed too bright. They were amazingly effective.
