Got a question for the collective brain trust here. We are told that vibration is bad for components and we should use products like
Stillpoints to eliminate it. I have heard the benefit so I don't need to be convinced. But nearly all high end amplifiers do emit a very modest, low level hum such that you can tell that they are on but not so much that you can hear them from the listening position. That is, not dead and inert like a rock. That you can hear the hum means it's probably pretty low frequency. My question is why. Is some kinds of vibrations like ones you can faintly hear ok but others problematic and need damping? I read somewhere that vibration products like Stillpoints work above 20kHz and shift the vibrations in frequency to where they do not matter. So is the answer that what matters is the frequency of the vibrations? Maybe just high frequency vibrations are the kind that hurt electronics?
