Hi Roxy, I would recommend seismically isolating both your speakers and each individual piece of equipment and rack. There are a wide range of isolators on the market that definitely do NOT work. I would suggest one of the following:
Ingress Engineering cup and rollers directly under your equipment, supported by a thick slate platform supported by either Machina Dynamica springs, Townshend Pods or a 12 inch dia. inner tube at very low pressures.
For speakers the easiest solution is Townshend Podiums but you could also use MD springs and/or Ingress speaker footers.
For rack isolation you can use either Townshend Bars or Pods, alternatives would be MB springs and/or Ingress footers.
For more detailed advice you are welcome to PM me.
