Maximizing VPI Prime Performance

You have one amazing set-it-and-forget-it table in the Cosmos, and you’re trying to chase that performance with a much lower level, tweak-of-the-day VPI? I’m not sure why you decided to abuse yourself in this manner :(
Those 2 companies have polar opposite philosophies. Look at the SOTA Sapphire/Star/Nova, still produced from the 80s to today in the same basic design with material upgrades and refinements. Whereas VPI runs through countless lines, designs, Mk versions, tweaks, updates, etc. Imagine buying a Classic Direct for $30 K a few years ago, and then seeing the HW40 being touted as superior for only 15 K.

Perhaps consider get a refurbished Star/Nova if you really need that 2nd deck?

Also I have a ring clamp on my Clearaudio deck, and the only way these items make sense is if they are machined for your specific platter, so that they can go on quick & centered (the Clearaudio ring works like this, with a lexan adapter lip for the platter). If you have to fiddle with some centering device, or eyeball it, then you’ll probably hate it. The SOTA vacuum hold down is a joy to use. 

Well the ring clamp did not work out for a couple reasons. It will be going back. Will give the Symposium isolation base and foot inserts a try.

I use the second table for casual listening. Hate to burn hours on the Proteus when I am doing dishes, playing chess on the computer, surfing the web, or doing other things in the house. Yes the Cosmos is awesome, I would just like to squeeze a bit more performance out of this table, especially with this arm and cartridge package.

It's my product. PM me for information. I believe you'll be pleased with the results.

Placed my order for the Symposium Audio Segue Iso platform and for the Prime feet inserts. We will see how this works out, and how long the back log is. Last week I removed the Ortofon A90 from it and installed the ZYX 4D and got the overall presentation closer to what the Cosmos and Transfiguration Audio sounds like. Not as resolving, not as focused, but closer to overall sound, which is nice to have from my casual table. If I can improve the overall clarity and focus, that would be great for me, as it would then be a viable second option for those casual listening times.
