Since no self-respecting, audiophile, least of all any of us, places a component in direct contact with a shelf, with no intervening exotic footer designed to isolate the component from the shelf, I think it makes very little difference what kind of wood is used for the support system, so long as it is very stiff and rigid. The issue of transmitting energy into the structure and dissipating that energy is moot, if you have a good footer, which all of us do I am sure. Also, I think we all broach subjects like this on the premise that there are vast amounts of energy to be dealt with when in reality the magnitude is relatively tiny to begin with.
How does wood hardness affect the sound of a TT on a wood TT platform?
I'm interested in purchasing a Butcher Block Acoustic TT platform for my Luxman PD-171A TT. The Maple Block has a Janka Wood Hardness Scale of 1450 while the Walnut is rated at 1010. How does the hardness of wood affect the sound ? Trying to decide which way to go.
