Vibration - What are the Main Sources?

I've used inner tubes on heavy bass bins on concrete. It really effected the way the TT worked.. Radio stations by the freeway trick.

Over air the tube get craft foam blocks put them in the corners under the subs box. THEN let some air out until it just rest on the craft blocks.

I isolate, multi springs in holders and some type of soft silicone platforms. Adding weight works. Wrapping a quiet brick vs a noisy one help too. 

For "Rack mount" spring load between components, that works very nice. It adds load but not to much weight..

There are some VERY effective low cost solution to vibration control, how they do look vs how they should look is a different story.. 

There is some easy effective more expensive alternatives to.
Great looking, easy to install, easy to adjust and very effective is appealing.

MC provides good information as usual. But what is he talking about in the rest of his comments? Airing personal grievances, paranoia? It has nothing to do with the subject matter in this thread. 
Anybody else confused and tired of reading it throughout the forum?

I’m more and more getting the feeling that there is more than a little quid pro quo happening on this website, name brand advertising for benefits.

is this an admission of guilt? You can tell us, we’re all friends in here, aren’t we?

Maybe one of the haters is having second thoughts

Haters, haters, we see no haters. Much.

He uses isolation. https://systems.audiogon.com/systems/615 and cable lifters, what the? Shill?
If you're going to insult someone, because they may be haughty at times, it may not pay to dismiss truth.

That, and some major rotator cuff strain from all the patting oneself on the back. 

rubbed the wrong way nonoise?

Vibrations, the good the bad and the ugly. Obviously we want the good vibrations, and reduce the bad ones. And doing that selectively takes knowledge, and effort and an attitude that will allow for learning.

Sometimes people have vibrations, and these vibrations meet with our own nodes, they are recognised and well, the reaction can be pretty uncomfortable.

Interesting that you chose such a specific injury, close to home perhaps? Repetitive strain injury in your past in the shoulder joint perhaps nonoise?
