vibration control

The BEST vibration control I found was inside the gear not under it. I took off the top cover and put four layers of Wal-Mart brand of teflon tape all around where the screw holes are on the top chassis for the top cover.

Next, I took off the bottom plate and put four layers of teflon tape all around where the screw holes are on the bottom chassis for the bottom plate.

You don't put any teflon tape on the top cover or bottom plate parts, you only put it on the top chassis and bottom chassis of the gear only.

I did this tweak to my Yamaha a-s2000 integrated amp it now sounds much more musical !..

This is a must try tweak for all your gear !!

Encase the entire component in cement? With openings for the cords and controls of course.

Rok2id... The idea of making speaker enclosures out of concrete proved ineffective. Concrete rings like a bell.

I have my speakers on concrete paving stones. to get the tweeter height correct. Is this a good idea?

A couple decent treatises, on vibration and control, follow. If some don't believe in the effects of vibration on electronics, or can't hear the results: let them enjoy their, "bliss." (http://www.pandathumbaudio.com/vibration.htm) (http://www.gcaudio.com/resources/howtos/vibration.html)
