New Turntable Direction

It's been a long time since I sought the opinions of the community.  I have been a happy Linnie for 20+ years stopping after upgrades with the Ekos, Cirkus, Lingo, and suspension.  I still have my Shelter 90X.  A recent upgrade inquiry resulted in approximately 6K investment in my table and this just doesn't seem to make sense considering it's age.  I have considered investing the 6K in a new table and staring all over.  I have initially looked at Oracle, VPI, and Basis in part because they have been around for as long as I have been doing this.  For what it is worth my phono stage is still a Rhea.  So what do you think new table or another Linn upgrade and if new table what brand?  As always I appreciate your feedback.
Thanks all but I'm not sure which posts are response to me or the OP.
I have a Benz Micro Wood M2 with minimal play that was just serviced at VAS. So it is like brand new.
I like my Basis 2001 w/suspension. I've never read a bad thing about Basis. I THINK the motor is high torque.  And the motor sits off of the plinth. I know the bearings etc are very high tolerance and precision. But, it was recommended to me by Basis and dealers to get the Calibration Base along with the Vector 4. That is $8,000-$9,000 right there. With any substantial upgrade I do believe it is time to upgrade from my McCormack Micro Phono Drive as well. That is why I was considering the Vertere Mg-1/SG-1/PHONO-1 rig as all of that, even with a tonearm wiring upgrade to hand built is in the $9,000-$10,000 ballpark.... But, very different designs. MG-1 motor on the plinth and no suspension(I think).
@xagwell Your Linn has a great upgrade path..Karousel and Radikal along with either a Kore or a Keel. Karousel is the first in line, then Keel or Kore and lastly the power supply. Having said that, a top end Basis is where i would go next if going away from a Linn. Not a model like the 2001 or even the 2500, but 2800 Signature and up. Very pricey upgrade but one of the few tables that I have heard that can give slightly more SQ than a LP12 Klimax ( mainly due to the ability to have a Vector or Superarm 9 arm). The Linn LP12 is hobbled at this level by the Ekos SE arm and its weak phono cable.

You should start your own post with your question.

" ... it was recommended to me by Basis and dealers to get the Calibration Base along with the Vector 4."

Look for a used Vector tonearm. They show up from time to time.  It will make a huge difference. I was skeptical, but adding a Vector tonearm to my Basis 2001 allowed me to understand the importance of a good tonearm. Hifishark will make your search easier.
I do know I need to upgrade my tonearm more than anything. While the 2001 is very precise(as is Basis's slogan)I just am unsure if upgrading the t.t. will add an even higher level of sonics...Yes. I will start my own thread. Thanks.
xagwell, I think you were on the right path with Basis and Oracle. I personally would never live with a turntable that was not adequately isolated. The other three turntables that are adequately isolated are Sota, SME and the Dohmann Helix.
The SOTA Cosmos is easily the best value. The Dohmann is easily the best turntable of the group and the price reflects that. 
The Cosmos has several very attractive features. It has vacuum hold down, the best isolated dust cover which can be used while playing a disc, an excellent motor with excellent speed control, and a magnetic thrust bearing similar to what Clearaudio uses. On the problematic side the Cosmos limits the tonearms you can use. I think an Origin Live Enterprise would be perfect. This would certainly run circles around your Linn. 
Having said all this you can isolate any turntable by putting it on a MinusK platform but this would add another 5K to the price. The Dohmann has MinusK trickery built in. Michael Fremer uses a MinusK under his Continuum. 
Good luck and do tell us what you wind up with!
