VPI turntables

I am one of those former VPI users, never quite did it for me, move from 9" to 10.5i arm not big deal. My issue is belt drive not for me, so DD VPI would be more aligned with what I'd do, and move away from unipivot.

'I'm looking at these models as they are currently on sale in the $3500 range I'm also willing to look at used tables.'

This listing is in meets your requirements, and unlike the other link is available to ship.

VPI Prime Turntable Reduced Priced to SELL For Sale - US Audio Mart

This listing has  has the right title-" PRICED TO SELL" which to me means seller will be open to negotiation. Work in an agreeable shipping cost, and you will have a nice upgrade.

If you are going to achieve a significant improvement as has been claimed, I'd suggest there would have to something drastically wrong to get that level of benefit. At best you'd likely achieve a minor improvement.

Before you even considering upgrading, I'd recommend that all cables and interconnects should be the absolute best you can afford so you know are getting the best possible connection from the stylus, to each piece of equipment and finally onto your speakers. 

I know some folk maintain cables are merely cables and digital is simply 0's and 1's. Ignore them for they are ignorant of the details.

If you not completely happy with the unipivot, VPI has a 2nd pivot mod that I use...its about 100 dollars and is worth the cost and setup time.

I no longer have my VPI table, but +1 on the dual pivot mod.  Easy to do and no more wobbling.
