bb tweeking again. help me

I bought a Billy Bags stand from a guy that installs custom audio video and designs the the rooms,basicly high end projector rooms and he told me cat litter works good as a vibration damper and it is cheap.I saw the room he set up at his own house and though it was out of my price range the guy definatly knows his stuff.Has any one heard of using cat litter to fill racks and stands ?

Of course, with cooked rice the CDP may show a preference for songs by Edith Pilaf...

Long grain or short grain?

I read an article that Basmati has better vibration absorbing properties than does
brown or white types of rice;)

I have used cat litter in the past to fill speaker stands. I find it works best in combination with lead shot.
