The choice of platter, if one were to upgrade, may be limited by the cutout in your plinth. IOW, not very platter is an option for every TNT. I have seen Mk3's with Delrin/lead insert platters, not the Delrin/aluminum sandwich. I would also be careful about the description of the aluminum platter being "less colored". Leaner than the Delrin or acrylic platters, but that is assuming that one considers the weightier sound of the other platters to be wrong; I don't.
French_fries, my TNT6 is actually a hybrid with a MK5 platter as Brf suggests. For whatever it is worth, and to go back to the issue of the aluminum platter's sound, according to Mike at VPI the MK5 platter is "along with the Super-platter, the best they ever made".
