I like the look of these - I am thinking seriously of ordering 4.
Yeah, get 4 of the 9" stands.
I love these VTI modular stands. They come in 7", 9", 13" height and a few different colors. You can stack them to the height you need. I use them for a lot of things - audio racks, end tables, night stands. They just look great for everything.
My 110 LBS ATI amps sit on them. So definitely strong and stable.
