This tweak is system dependent. Place vibration sensitive components on half inch thick glass slabs. A local glass shop charged me $25/each for 14" by 18" pieces. I rest the glass on top of BDR cones or Isopods. This results in a subtle, but worthwhile improvement in overall sound quality.
Cheap Tweeks
Does anybody have any cheap tweeks to share with us to further our search for "affordable" sonic bliss? I have 3 for you to try that anyone can afford. 1) if your amp sets on the floor, try putting 4 tennis balls under it. you might want to place a piece of half inch plywood under the amp first. 2) If you need to isolate your components better, put a piece of plywood under them and then put the largest size bubble wrap that you can find uner them. These ideas work and are much cheeper than big buck isolation platform. 3)If you use "dynamic" speakers, put a quarter at the top front corners and a dime in the center. It must be the resonence of the change that does the trick. All I know is that it works.
