I agree with the Basis rep regarding the Vector tonearm and it is a great tonearm. I had personal experience with that upgrade and it might be the single largest improvement to my system ever.
I have not heard the Calibrator Base or Cable Isolation System so I really don't know how much improvement they will add to your system. All these things are additive, so I assume the other upgrades would result in an improvement, the question is how much, and I don't have an answer for other than the Vector. That improvement is massive. I have not heard the Superarm, so I don't really have an opinion on how much better it would be than the Vector. It seems like a lot of tonearm on the 2001 turntable, and you might want to spend some of that money on a great cartridge.
After the Basis Vector upgrade I went through a significant upgrade spiral brought on when I heard how much better my system sounded with the Vector tonearm. I have my system posted, although some of the pictures require updating. You can see it here https://systems.audiogon.com/users/jperry
Best of luck with your audio journey
