Vibration Theory - Isolate or Drain?

The best approach is to isolate AND drain. Isolation is not highly effective for frequencies under 10 or 20 Hz anyhow, so residual energy in the system can be dealt with by draining or damping.

Its as if your gear in a mechanical sense is all cap coupled from the inside to the outside environment and back again. In some worlds cap coupled is the color of the day. So called isolation devices are indeed crayons from some kids tool box. Tom

Solid base under components , solid bass response . Balls , cones , springs , spikes , under gear , better detail , air . Thats not a consensus just an observation . Ya right a consensus on an audio forum ? ! ? !
Carbon fiber cones and platform makes my transport happy , but my A.R.C Dac 8 insists on direct contact with a heavy wood base . Go figure .

i use only absorptive, soft materials under components.

my product of choice is a polyurethane-based sound booster.

i use 4 per component. the durometer varies with the weight of the component.

my second choice is furniture foam. my digital components are sitting on furniture foam.
