Large brass devices on top of power amps ?

If you need to put weights on equipment to stop it from ringing,the equipment must not be designed very well.Just my opinion,nothing more.

Leave it to audiphiles to complicate a very simple concept. All the MASS is for is to dampen/reduce vibrations getting to the electronics. So use something that has a lot of mass (a baggie of lead shot comes to mind - don't eat/breathe it) and will couple well to the item it is sitting on.

You could even use a heavy statue or even a rock that has a flat broad base to accomplish the same thing. Dyna-mat type material or sorbothane will provide good coupling. Or just keep it simple and use felt.

Also, do what car audio enthusiasts do with stuff like dyna-mat to kill vibrations. You can line the inside of the chassis to accomplish this. Don't block the vents!

The use of small pucks and disks are for the psycho-acoustic crowd - they work great if you think they do.

And to think everyone said we shouldn't stack components;-)

I use edensound stuff from Vermont Audio - very well made and not to expensive - on the other hand I'm not at all sure I can hear a difference on my EMM Labs CD Player or Atma-sphere preamp - so either the gear is designed well, or I don't hear well enough to pick up any noticeable difference, but they look nice and offer proof of my audioneurosis bona fides.

I don`t know who`s complicating anything, some components are built with thin chassis tops that could possibly benefit from mass dampening. Listener57 raised a good point regarding the detriments of over dampening, just a factor to consider that`s all.

Chalres1dad, Tpreaves also makes a good point - should any well designed piece of gear require any additional external weight to improve its performance based on vibration damping? Or is it just another product niche offering audio benefits that equipment companies can't figure out how to provide the listener for themselves? Maybe, maybe not.
