Fibre board is decent but not quite so non-resonant. It has a definite hollow "toc" sound if you knock on it. For best resonance dissipation, you need high mass combined with inertness. Spurious energy emitted from the stylus/groove interphase and from other sources is directed into the object of highest density/mass and dissipated as heat (Newtonian law). Thus a heavy and inert platter of low resonant signature works best.
Thanks for your comment. I agree that high mass is the ideal but because I used the bearing thrust plate from the original MMF-2 (which is not design for heavy loads) I could not increase the platter's density too much.
The componenets you used from the MMF-2 are just fine. They just needed to be used in a better product...as you did...the Pro-Ject arm is decent and the motor is decent as well. The upgrades you did wll show what those parts are really capable of.
i think that would be a nice weekend projekt^^

Never heard of using MDF for a platter, but it makes sense because of its non-resonant properties. Good job!
