VPI Classic 3 Upgrades or Move On to Something New


I'm the 2nd owner of a VPI Classic 3, bought here on Audiogon in 2014.  Cartridge is Soundsmith VPI Zephyr.  Considering giving it some new life with a JMW 10-3D Unipivot Tonearm, Signature Feet, and ADS Speed Controller.  Total upgrade cost - $3,950.  

Or...should I go in a new direction and give another turntable a try?  I have no complaints about my current setup, but don't have a frame of reference for what I might be missing out on. 

Budget for a new turntable/cartridge combo is anywhere from $5,000-$10,000. Thoughts?

tablejockey's comment about a good phono stage is a good one

but certainly not exclusive of getting a better performing table
Currently swapping in and out two integrateds with built-in phono stages  - Vinny Rossi L2i SE w/L2 phono module and Linear Tube Audio Ultralinear w/ MM/MC phono stage.
jjgasp,

I own a Classic 2.7 (sic).  Basically a Classic 1/2 plinth, which I upgraded by swapping out the tonearm, base and motor.  My back-up cartridge is a SS Zephyr.  My regular cartridge is  Lyra Kleos. 

Your OP states that your cartridge is a SS Zephyr.  If 1st generation Zephyr, you can get more bang from your buck with a cartridge upgrade.  The Zephyr (1st generation) is an ok cartridge, but just ok. 

Agree with comments above re phono pre.       
I would give a call to Matt at VPI.  He is very easy to deal with and honest.  Ask him for assistance.
