Platter upgrade for VPI MkIV?

The HW-19 is probably the most "tweakable" Table VPI ever made. A bit unsure what Platter you have, is it Lead Filled with a Cork Ring underneath? With 3 Adjustment Pins by the Spindle?

The Classic Platter would most likely sound different, but perhaps not necessarily better. That may come to be a personal opinion of one versus the other?

While VPI no longer markets the Super Platter, it appears Elusive Disc still has stock of these. As far as I know, all VPI Platters, with the exception of the HR-X Super Platter should be a drop in fit on any other VPI Table.

I would assume that as some have claimed, the Super Platter was the best VPI ever made, and again would assume just due to sheer mass-weight(at 25 lbs), that there would be sonic benefits to be had.

Lowering noise floor to a stock HW-19 can be accomplished a number of ways, experimenting-substituting suspension components-materials to Base, different Feet, Shelves, Racks, Bases, modification to the Stock Motor, and Motor Mounting Hardware within the Base.

And there's the VPI SAMA.
And as well the VPI SDS Speed Controller, to lower Motor Noise Floor, and also correct for slight speed errors, inherit on all VPI Tables. Mark

Keep what you have. The difference is mostly the platter itself, not wether the bearing is inverted or not. I have the same platter that you have on a TNT6 plinth. It was an improvement over the thick, black, acrylic/lead platter. BTW, I believe that what you have is a MK5 platter. Acrylic/steel sandwich.

According to Mike at VPI in one of our conversations: "It is as good as any platter we make/made, including the Super Platter"

Mark, my platter was called TNT 2 when I bought it, it has no lead (that I know of) but does have a cork ring, and the 3 small micro-point adjustment screws. I think I've got the isolation and suspension worked out pretty well and I do have a SAMA and a SDS.
Frogman, I just received an email from Mike at VPI and he says as far as he's concerned, he wouldn't listen to anything but the Classic platter. Go figure. He did say that it is larger in diameter so I don't think it will work with my super thick armboard and ET arm.

The Super Platter and Classic platter indeed will not work with the ET-2 arm, as the platters are too wide. I had to ditch the ET on my TNT when I got the Super Platter.

Well... years later and much more experience later...

( I can't count on my many fingers, how many times I've read the phrase, "((someone)) at VPI said", ("You have one of the best platters we've ever made.) So, this phrase has little meaning anymore. In fact, it has no meaning because Harry has made SO many changes in such a small time frame,... how in the hell is an end-user suppose to know what they have.. or at the very least, how, what they have sound like, by comparson to what the hell ever that VPI decides to make public???

Since this thread arose, it turns out that upon my experience, Frogman was wrong! He stated the difference between a non-inverted bearing and an inverted bearing will not be the main difference. Wrong, wrong wrong!!!
