Isoacoustics Orea vs Townshend Seismic Pod on Components

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.

Thank you.  I have the matching Ref 2SE Phono pre as well.  I have been an ARC user since the late 80s.  I try not to chase the wind.  I enjoyed my last ARC preamp for 18 years.  I'm very fortunate to have these preamps.  

I find the Nobsounds to be effective isolators.  I'm using large springs on my speakers and amplifiers.  I bought some 1.5" OD 57 lbf/in springs from McMaster Carr for these heavy weight components.
