Pro-ject Xtension 10 vs. VPI Prime vs. Amadeus


I have a Well Tempered Amadeus currently, which I have owned for 2 years, and been fairly happy. Just curious if one of these new high mass turntables would be an upgrade, and if so, which one?
Particularly interested in hearing from someone who has compared the Xtension 10 to the Prime.

Do you feel you have played enough with Damping (golf ball) cup, and VTA. Not trying to second guess, but it does make
a difference, as you are likely aware of.
The Amadeus will be hard to beat. I had a Nott Spacedeck prior to mine and the Amadeus made it sound broken.

For 3500, the VPI Prime is hard to beat. The 3D arm is one reason it's called Prime. The VPI tables are reliable as Hell and do not need constant tweaking. They sound like music.
