Butcherblock Acoustics "feet" effecting sound and isolation


Hello, general question here do you believe the feet being used under a Butcherblock Acoustics platform effects the overall sound? I'm using metal spikes resting on metal decoupling discs that I ordered from Butcherblock instead of the stock rubber feet it came with. I have maple butcherblock under my phono preamp (3 inch), all tube preamp (3inch), and amplifier (1.5 inch). 

Also do you think I could be over isolating with all that? I'm gonna do some experimenting this weekend but just wanted to see if anyone had thoughts or opinions on it. I've read good and bad things about isolation and over doing it. Thanks for any responses!

Good reference to the Cardas video. It is great when someone simply demonstrates an aspect of audio… few words needed. The point is irrefutable.

 

Also, the follow on video describing the Cardas philosophy and progressive change in sound characteristics is something anyone considering cables should hear. It is short.

There are 2 main issues that isolation devices may solve.

#1 is external vibration to the component (e.g., footfalls causing a record to skip)

If you have a solid floor and solid rack/stand, and footfalls are a non-issue, this should be easy to solve and not involve tire tubes and sand boxes. (I have zero footfall issues so my solution is designed around that scenario)

#2 is internal vibration generated by the component (integrated tube amps and CD transports are among the worst offenders)

#2 is addressed by coupling the component to allow the vibrations to dissipate and absorbed by something that can convert that energy into heat. In this case, sorbothane, wood etc. makes it worse. In my case this simply meant removing the plastic "buttons" on the bottom of the metal turntable feet and removing the stock rubber/plastic feet from my amp, then applying several different application-specific solutions from Symposium. They are reasonably priced and they work. Peter knows his stuff.

Details are in my virtual system in case your are interested.

The biggest impact was my integrated tube amp, followed by the center channel speaker. (not listed in my system but I use JR. roller blocks to lift the Paradigm speaker off the wood cabinet instead of having it sit on stock rubber feet, or sorbothane pucks, and the clarity and detail improved - a LOT), then TT.
