Is anyone using sand boxes under their speakers ?

All of my components are sitting on Brightstar platforms except for my power amp. However, I have never used the platforms as speaker stands. Mapleshade records sells maple speaker stands, but they are a little pricey.

If you are interested in maple stands, I would consider just purchasing a pair of 3-4 inch maple cutting boards for a lot less than Mapleshade. I am actually using one for my power amp with excellent results. Checkout this web site:

I quit putting my speakers in sand boxes years ago. Every cat in the neighborhood was in there with them.

Thanks for the responses. I'm going to go ahead and make some sand boxes and see just what happens. I'll report back in this thread in a week or so. I've never read a single negative thing about Brightstar Audio's products, so I can't really imagine things changing for the worse, and they are all about sand filled isolation devices.
PS: No cats allowed !

I once had bookshelves sitting on plastic crates crammed full of journal articles - was strapped for space at the time, hence the dual function, storage and speaker stands. Sounded great.
