Can someone explain to me what the purpose of putting your electronics on a special stand? I think the reason is to "isolate" it from vibrations. These stands or "bases" are sometimes super dense like marble, and sometimes just a chunk of wood that sells for a ridiculous price. So, are these to remove the vibrations? Basically, what is the claim for their existence?
Second question is then if they actually do anything. Is there any effect of putting your amp or dac on one? While I highly, highly doubt there could be any sort of audible difference, I guess it wouldn't be surprising if keeping electronics away from vibrations could help it live longer.
I kinda expect this to be like cables or power cords. People get a good system, but want to "upgrade" it and the companies and salesmen are willing to give them more things to buy, but that is just speculation and I would love to be "edumacated."
