Hardwood audio rack

I'm having my local carpenter build me a hardwood rack, made from a set of platforms each of which is supported by two vertical planks cut into a v a the bottom fitting onto the next platform (this appears a popular current design - see kimber et all). My question is, does anyone have experience of different kinds of hardwood? I can go with a heavy straight grain, or something very burred. I use RDS cones on the source which are designed on the principle of dispersing frequencies through random combinations of materials, and I notice that burred hardwoods have this random quality. Any views?
