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."

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!
Go to the Jean Nantais website and see if it might be a good fit. I've been with him 15 years and he changed the way I listen to music and what I hear.
I know it's been a minute since I've been here but the pandemic, retirement and now end of golf season has brought me back.  So first thanks for all your feedback so far.  I still have not done anything but mentally believe 6k for radikal, keel doesn't sit well.  Can't really move on the cartridge until TT decision because at the 2-4K range tone arm mass is important for proper matching and I don't want to limit my options later.  Basically I'll chill until I decide on TT of which I am still attracted to Oracle/Basis.  I gave the Sota Millenium a peek before I wrote this
