Vibration - What are the Main Sources?


A current thread discussing the best tweaks gave consistently high ranking for component isolation. I am curious to know where all the vibration is coming from that we are addressing with isolation. I understand that high volume listening can create significant vibration, but for the sake of this discussion let's assume we are listening at moderate levels. Can the vibrations from moderate sound levels affect the quality of sound? Are there other common significant sources of vibration that we are guarding against that can dramatically affect sound?

“Primarily looking at more isolation for the Schiit components for starters.”

@zlone, 

Please take a look into footers from Herbie’s

I isolated my components by running the speaker wires through the wall to my listening room.  I often say, "Nothing is the best", but this actually is.  Of course, I don't get to show off my stuff, but that is not why I own it.
"zlone" = Corvette or Camaro?

Neither :-). Though loosely related to an engine additive. 
Great discussion, thanks for all the feedback. It sounds like some real results can be achieved with the right solutions. Per my other thread on subwoofer isolation/anchoring I ordered some Nobsound springs for low cost experimentation. I will let you know what I hear. 
It does NOT affect the sound, it is just an annoyance.
Care to explain the logic behind that one?
The author of that article states:

Likewise, I can't bear to hear/ read actual snake oil vendors claiming that you'll get "cleaner highs", "more authority in the bass" or any of the other stupid things you may read elsewhere. The purpose is to stop transformers from growling (usually at no or light load). There is no magic, and it doesn't improve anything other than reduce the acoustic noise from the transformer(s). Anyone who claims otherwise is probably lying.
 Sounds like something you latch onto. Very self reinforcing.

All the best,
