Slaw, you asked the question about platter upgrades six years ago. You got several opinions on what to do, in essence, "keep what you have" was the response. Now six years later you decide, in your opinion, that response was wrong. OK, that's fine. The problem is when other people seem to contradict it, it's not fine. Everyone here is expressing opinion, most of us have limited experience, but want to share our experience with others. That's how we learn. Sometimes the things we learn don't jibe with our experience, so be it. Each of us experiences this hobby of ours in different ways, hence the common phrase "your mileage may vary (YMMV)". In this case you and Stringreen have differing mileage, it's not a big deal.
Platter upgrade for VPI MkIV?
I'm hoping some of you can answer these questions. I'm using the non-inverted bearing and a TNT II platter (acrylic/metal?, sandwich). Is the inverted bearing a significant upgrade and is the (new) Classic platter (aluminum/stainless) superior to the Superplatter? Is the inverted bearing a snug fit in the MkIV plinth? My bearing has a flange with 3 holes for small bolts to secure it to the plinth. The inverted bearing has one large nut on the bottom therefore it seems like it would need to fit snuggly in the cutout of the plinth.
