Which wood and design for diy monitor stands?

I built a pair of stands modeled on the Skylan stands. I used Ipe, which is a Brazilian hardwood I believe, but it is the hardest, heaviest wood I have ever seen. You can't nail through it, and you have to drill your pilot holes for the screws the exact same size as the screw, or the screw will break off. I used 1" mahogany for the top and bottom panels, glued and screwed to the Ipe 4x4's. I then mounted spikes on the top and the bottom. You can see a picture in my system profile.

Hey, aaawwww, thanks for the nice words gents. I did think about trying to have the posts go all the way up with out the plates, but decided to go with the Skylan design as people seem to like them.
AFAIK, Ironwood is different. Our home is surrounded by an ironwood fence, and I thought the ironwood in mexico is like mesquite....Anyways, the ironwood here cuts like butter compared to the Ipe which dulls saw blades, and drill bits. It could be like Dolphin, Dorado, and Mahi-Mahi, same fish, different names, depending on your geographic location. Maybe what I think is Ironwood.......really isn't Ironwood at all? The rest of your description of working with Ipe is right on. I think it works pretty goods as vibration absorption and I am planning on making a component stand out of it. I wouldn't think it is too rigid as you can still gouge it pretty good with a hammer, so it does absorb some energy.
