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.

Rumor has it that VPI is discontinuing the Classic line of turntables...(I have the Classic Signature w/SDS)... If true, look for some deep discounts around the holiday season.

I finally took the plunge on a VPI classic 1 SE in the walnut finish.

Music Direct has them on clearance and I think it's a good deal at only $300 over a new Scout.

I really like everything I've read about the Acoustic Signature Wow XL. I almost bought one, but I would've had to settle for an entry level tonearm with that table to remain within budget.

I was also very close to continuing to upgrade my Thorens, but I think the VPI will probably outperform a fully upgraded TD16X. I will likely move it on to a new home, assuming I will like the VPI.

Part of my decision was the ability to return the VPI without hassle if I'm not impressed, and VPIs reputation for customer support.

I'll keep you posted on my impressions. Thanks for all the input.
