Differences between VPI Prime and Aries 2


I currently have an older VPI Aries 2 turntable with the acrylic platter.  I'm considering trading it in / trading up to a VPI Prime turntable.  The longer I look - the fewer differences I'm seeing.  Both tables can use or come with the JMW tone arm.  The motors are more or less the same too.  I plan to keep my Ortofon 2M black cartridge and use it in a new deck. 

I'm not seeing huge differences to justify the "upgrade" cost.  What am I missing?

I'd keep the Aries and see about upgrading the platter to a Classic / Prime platter or an Avenger platter.  Might need some spacers under the arm and maybe a SDS (or similar) to adjust the platter speed.
The primary differences are the aluminum platter, a $1000 upgrade to Aries, and the 3-D printed arm, $1800 (10" arm)  upgrade to Aries.  If you want to do either of those two upgrades then it may be worth it to go with the Prime.  Now if you have the extended Aries which uses the 12" arm then you can't make a direct comparison since the 12" arm will not fit on the Prime, at least without looking very odd.  

Thanks for the comparison pmotz - that's the information I was looking for.  I didn't realize the 3D tone arm & aluminum platter were that pricey - that puts things in perspective.

I've also learned that VPI's optional (~$1k) periphery "outer ring" clamp only works with the aluminum platter.  It will not fit the acrylic platter on the Aries.
