currently own a vpi scout, looking to upgrade

Since you have a well thought out system to begin with, I would highly recommend a motor controller for your VPI. I implemented a Walker motor controller on my Scout and the positive attributes are undeniable, well worth the asking price.

Call Harry and ask about upgrades. There are several of interest.

I always wondered about the motor.

My experience as a long-time VPI Scout Signature owner strongly suggests that the most effective upgrade would not be a new TT, but rather a VPI SDS motor controller (highly worthwhile!). Assuming your speakers and amp(s) are top-of-the-line, other possibilities, depending, are a better cart and/or phono stage, and balanced AC (Equi=Tech) for your entire system. Only then, when all of those items are addressed (to the tune of maybe $6000++), might a more expensive and perhaps better TT make some noticeable audio difference and, hopefully, an improvement.

OTOH, if one just wants to show off how much money one can spend...

I'd buy a used Basis and dump the amateur turntable.
