Upgrade Opinions, Thorens vs VPI


I'm looking to possibly upgrade to a better turntable.

My current setup is a Thorens TD166 MKII with the original tp11 tonearm. The table has a few mods including a solid cherry plinth and birch bottom with sorbothane feet. It also came with the 10mm spindle bearing, same one used on the TD160.

Amp: Rogue audio Sphinx 
Preamp: MM preamp built into the Sphinx
Cartidge: Shure M97xe with SAS stylus
Speakers: Monitor Audio Silver 8

The components listed above are my recent upgrades. I now think my table is due for an upgrade. 

I am considering installing a Jelco SA750D tonearm on my Thorens, since the tonearm is likely the weakest performing part of the table, or going with a completely new table.

I am considering the following tables:

Rega Planar 3 (possibly not a big leap?)

Rega RP8

VPI Classic 1 

Acoustic Signature Wow XL with Rega arm.

I am leaning toward the VPI, partly because I really like its look, but I do want the best sounding table under $3000 (subjective I know). Overall, I'm pleased with the current sound from my Thorens, so maybe the best bang for my buck would be a new tonearm. Some members have claimed that a Debut Carbon will blow the doors of a TD166, but in my personal experience, it's the opposite. So I'm thinking I'd probably need to spend over 1K for a real sonic upgrade over my Thorens.

Anyone have experience with VPI tables versus Thorens TD16X series? Any advice is welcome.

Bondmanp,

Thanks for the input. I haven't heard of Kworks but I'll look them up. I've owned a couple relatively inexpensive non suspended tables and a suspended Pioneer PL55x. The Pioneer was very good, I almost regret selling it, but I didn't care for its look. 

I owned a Debut Carbon that doesn't hold a candle to the Thorens, but the debut is considered entry level. The main bearing is about 1/3 the diameter. 

My Pioneer PLX1000 direct drive sounds very good, especially for the $400 I paid for it used. My TD166 has a more fluid sound which I prefer with some music. The Pioneer excels with electronic music...go figure. Some have claimed that the Pioneer can hold its own against some VPIs, even a Scout.

I will likely make the drive to Acoustic Sounds to listen to a VPI, but I'm afraid they'll have it hooked up to a much better system. Maybe they'll be willing to swap components. 

I've finally updated my virtual system and have posted pictures of my modded out TD 850. I tried to show everything that I did to it.

Helomech-
Ive been following this thread.
Your table clearly is deserving of a more substantial phono stage
Personally, I would  do a cart as well(LOMC)

IMO , I believe you just can't hear your table at its best without a good outboard phono stage. My preference is tubes, but very nice SS approach tube magic minus the noise some listeners won't ttolerate (high volume listening)
The nicer phono stage also makes an existing cart shine in its best light.

More food for thought.

My Rogue Audio Shinx has a tube preamp stage, though the output modules are Hypex Class D, I'm pretty sure the class D portion isn't in the signal chain of the phono section (why would it?) so essentially it is a tube phono preamp, allegedly the same one in their Cronus amp. 
Many reviewers claim the Rogue Sphinx's phono section alone is worth the price of the whole amp.
