Large brass devices on top of power amps ?

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.

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.
