vibration controll


I am wondering what some are using under sim gear(i5.3 amp)for vibration controll.I have a solid steel 5.3 series rack which seems adequate...but have units placed on shelves with points and nothing else.getting alot of vibration on amp mainly.Rack is sand filled,speakers are adagios and i wonder if would benefit have outriggers,thus lowering vibration.

My power amp is on the last shelf of my rack and is seated on a 2 inch thick maple platform.
your steel rack is the problem. Steel holds in much to much energy and it runs right up into your table if your using a turntable. I would worry more about the table then the amp. Do away with the steel and place your gear on ikea lack tables their only 8bucks a piece and work from there.
My speakers are on tv tray tops.They were just taking up space.I had a nice 5/8 hose.I cut pieces and all the gear has them under.Concrete cinder block? 2 amps & deck setting on a unused cutting board,setting on top of a cinder block. It is about the sound right?
