Large brass devices on top of power amps ?

I've used brass weights from Mapleshade for the last ten years, and found them to be effective in reducing vibration induced microphonics--leading what I hear to be clearer, tighter sound. Granted, and not to cause any more crazy-making obsessing (guilty: an audiophile trait), do brass weights beg the question of whether or not we're "tampering" with the carefully considered "voice" of the component? I'd be curious to hear how audio designers would perceive any change (negative or positive) to their respective gear with any type of mass loading.

Atmasphere,

Indeed, I like your response--good motto for this hobby--"Have fun and don't get zapped"!
