How does wood hardness affect the sound of a TT on a wood TT platform?

After nearly 4 years, the OP probably gave up and got real a real isolation platform-Minus K.

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.

Before I buy something I try to understand the physics behind it.  

As a Observer looking in, from my Keyboard End, it is seemingly easy to discover there are behavioural limiters that are stuck to certain individuals within this Analogue Forum like flies to a released motion.

The real Arch to Learning and New Found Behavioural Freedom is to be discovered when such as the following can be acknowledged.

   "There is a principle which is a bar against all information, which is proof against all arguments and which can not fail to keep a man in everlasting ignorance-that principle is contempt prior to investigation."

The real WOW to be found is when it is a regular practiced chain of thought where "contempt prior to investigation" is recognised in one's chain of thought and the efforts are made for it to be avoided.

This is not limited to an Audio Experience only, life is so much more fun as a Blank Page to be constantly filled up as an evolving Text Book.

A "released motion"? That's not nice. Are you still mad I pointed out your inconsistent posts?

I have no argument with you, personally (we have found some things in common with SME tonearms and Kontrapunkt cartridges). If you post contradictory things just say it was a mistake and it's done. But please don't get into scatology.

Let us try to be pleasant to everyone on this forum.
