Actually, the original VPI platters were of aluminum with a lead ring insert. When VPI moved to acrylic, also with a lead ring insert, it was hailed in TAS (then a credible mag) as a major improvement. I went through that transition and agreed. My near to original (but updated) TNT has the acrylic/lead combo at about 20 lbs.
VPI then gave up on lead (for environmental reasons, they say) and provided other acrylic sandwich platters for a while, including the super platter. Then for a while it offered acrylic alone; these were clear and not black. Then it gave these up for aluminum with a steel plate, probably for the weight and for any dampening it might offer. VPI claims good acrylic is hard to find (expensive), and maybe hard to machine.
I'm not going to get in a debate about what's the best, but I have never been willing to give up my acrylic/lead platter for anything that came later.
MY final word: I have been dealing with VPI for many years and do not believe Harry is the cynic you claim. I believe he combines his personal interest as a hobbyist (just like us) with a need to keep a serious business in the black. If you don't agree with changes being made, keep the old stuff, it will outlast you and your kids. Or, if you are just beginning and favor the older designs, you can buy on the used market with the assurance that VPI will offer you the same customer service as if you bought new.
