VPI Aries 3 - Funk Firm 3mm Acromat


I am thinking of adding a 3mm Achromat to my VPI Aries 3 TT. I have the super platter with the screw clamp and peripheral ring clamp. I was thinking of replacing the screw clamp and ring clamp. Instead, I was thinking of using a 3mm Achromat and a heavy HRS record puck.

I was wondering if anyone has any experience or opinions on this move? 

Does anyone know how many turns on the VTA tower would equal the extra 3mm thickness of the Achromat?

FunkFirm makes the 3mm mat for tables without adjustable VTA and it sounds great on my Rega.  I suspect that is a compromise and the 5mm mat may be superior.  
Don't do it. You are not going to improve anything over the direct platter and clamp that VPI designed for that table. I have an Aries 2 and tried something similar. It only degraded the sound. I do use a Herbies on my Technics SL1200GR though and it sounds better than the stock mat. 
If you really are looking for an improvement, check the VPI website - in Harry's section.....record weight.   The alterations you are considering are not improvements.
I agree with those who say don't try to improve on the super platter.  You might try substituting a center weight for the center clamp and removing the washer--mostly for the convenience of just dropping it on.  But that, the super platter and the peripheral weight should be about as good as it gets.
melm.....for me, the elimination of the SuperPlatter, with the installation of the classic platter was a very substantial improvement.  For all those with a spindle weight, go to the VPI website in the Harry section.
