Over the past ten year's, VPI's move to acrylic and now aluminum is puzzling. I have heard the acrylic's. The TNT Mark IV's seem to provide the best sound, often better then the Super Platter. The acrylic's that I have heard were terrible. If you want to try the aluminum, which does take the p-ring, have VPI grant you a return at full price paid, less shipping. Try it would be the only way to really tell. It must sound better in your rig, otherwise it does not make sense. I am thinking of changing my Aries but they will not give a return accomodation so I will sit it out until then.
