Isoacoustics Orea vs Townshend Seismic Pod on Components

I’d say stay with fewer springs.  That keeps the resonance point as low as possible.    The difference in gaps doesn’t matter.  This is static loading.  The only time the springs move is when you put your hands on the component.  As long as a gap remains once you let go the component is isolated. 

I appreciate the advice. It makes sense to stay with fewer springs.

My preamps are unbalanced due to the heavy transformers mounted to one side. So I set them on inert boards and then the boards are placed on the isolation feet. You can’t see it from the picture but the rear feet are positioned inboard to even out the loading. This way I still have the rubber feet on the component in use. I didn’t want to put the springs in direct contact with the chassis. Based on my accelerometer measurements the isolation this way is just as effective as having the feet directly under the rubber feet of the preamp.

Audio Research Ref 5SE. Nice.

Similarly I didn’t want to place the Nobsounds in direct contact with the chassis so I put them directly under the heavy duty cast-iron feet of the component. Due to the nature of the rack I can’t introduce an additional board between the feet of the component and Nobsound footers. My amp also has unbalanced loading, compensated by reducing the number of springs at location where the load is lighter.
