Do a search on “damping factor wood types”, there are some studies on the subject.
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.
