Best wood under audio components?

I am just about finishing my DIY audio rack and wondering about what type of wood would be the best directly under the components? 
I am from Norway and don`t have access to North American maple. Baltic birch plywood is rare also, because we have Norwegian. I would rather have other solid type of wood under my components than plywood, but the efficiency is the major consern, not the outlook.

What type of wood would you recommend?

Thank you! :)

@korakotta: I made my bookcase/ stereo rack out of maple because that is the hardwood species I had on hand.  In retrospect, I should have made it out of cherry to match the rest of the furniture.  My view is that this is an aesthetic choice not something that influences the sound of a system.  I would go with what you have available.

Depends what components and whether you are trying to damp the sound. Check out the comparitive hardness of woods here.
The harder the wood, the "harder" the sound. By harder, I mean more focussed, detailed and perhaps brighter. The softer woods will sound more mellow. But, as with anything, YMMV and different wooods can impart their own subtle color. 
There are 2 levels only on my rack. The top is the TT (VPI Classic 1), the phono (Gold Note PH-10) is under. Both of them are sitting on sandbox. Each sandbox has a tile placed directly on the sand. The middle layer is a tube, and I am trying to find the top layer`s material
I managed to get a maple board (Shun Mook) under my TT, so I am looking for the wood under my phono.

+Both of my studio monitors (Dynaudio BM5 Mk3) under their factory stand (sittin on sand)
What would be the wood of your choice? -not maple, not baltic birch ply-

Yeah, ideally depends on components and on what you try to accomplish. But the OP is not going to listen to dozens of woods under all his components. I would just choose Michigan Maple or maybe Black Arkansas Walnut and call it a day. In any case, what's under turntable is of course most important. I prefer natural materials, generally speaking.
The thicker the better, due to higher stiffness. I would choose a hardwood ply if constrained by budget or maple, oak, bamboo, etc. if not constrained. 2 to 3 inches thick would be nice. The wood board should ideally be placed on cones.
You should have included all the info in the first post!
I use a 1 cm thick piece of solid walnut glued on top of the birch ply plinth for one of my 401 turntables. It sounds great. See systems. I use wenge for my armboards on the recommendation of the man who made my slate plinth so you might look at that.
I use salt blocks (sold for cooking). Heavy/dense, zero sonic signature, and cheap. 
Oops. The man is in Norway. I confused this thread with another one regarding same question.
What do you have in Norway ?
@glow worm,
That is a very interesting way to go. Who woulda thunk it?
I got to try it, as well as using them to cook my steak.
I have heard salt blocks such as the Himalayan salt can sweat with changes in temperature and humidity. This can be very corrosive. I would use caution with salt blocks. 

Hi korakotta

Here's a Tunee in Norway you might want to read up on.


There were lots of Himalayan salt lamps in exhibitors' rooms at CAF.  Was it just for atmosphere, or do they know something we don't know?

(Synergistic Research, look out!)

Some have tried the Bamboo cutting boards from IKEA, and like them. Surely their are IKEA's in Norway!
Himalayan salt lamps have a nice warm glow and provide low level light in the space. Other than that I doubt they do anything although they were and maybe still are msrketed as producing negative ions since salt is a pyroelectric material, I.e., produces negative ions when heat or voltage is applied. In the case of the Himalayan salt lamp the wattage of the bulb supplied is not suffientky high to produce anywhere near enough heat to produce negative ions and replacing the bulb with a higher wattage bulb doesn’t help. But they are pretty, I’ll give them that.
Thank you for all of your helpful comments!

I have a chance to choose between Norwegian maple, Ash, White Oak, Red Oak, Walnut, Elm, Ceder, Mahogany, Pine, Norwegian Birch, Elm, Siberian Larch.

Which one would you choose and why?
