Hi,

Willing to build new TT out of TD125 Mkii chassis. My idea is to fit it into new plinth, armboard, and add SME3009 arm.

I'm wondering which material should I choose for a plinth. I'm considering either MDF or stone one. My choice for now is http://m.ebay.de/itm/331959247803 . It looks awesome, but am not sure whether it will sound good as well... Do you have any experiences with such kind of solutions?

For armboard I consider to get one of those:

Again, it seems that stone would be the best as it would be perfect isolation for the tonearm, but maybe I'm wrong...

MDF is one of the best materials to use. If you combine it with another material, aluminum, carbon fiber or stainless steel, ala, a sandwich, that would be even better.

Stone resonance frequencies can be problematic if not controlled properly. I have had great success using 3 to 6mm carbon fiber for arm boards. Again, you can make a sandwich using two sheets of carbon and balsa-wood in the middle.

Recently, I used solid cherry and maple as plinths, instead of MDF, and both worked extremely well. They both look fantastic, too.
