Tonearms: Graham 2.1 or 2.2 vs Basis Vector

Hi, I have a Basis 2001 with Rega RB300 and am finally edging toward tonearm upgrade. I had been figuring on getting the Basis - seems the default best choice - but I hear that Basis now has a "Vector" arm in the same price range that could be competition, particularly in that it was designed for the Basis tables. I've also heard interesting comment about a tonearm called "Schroeder".

Have any of you heard the Vector or Schroeder, and could comment on sound quality and appropriate match for Basis 2001?

Cartridge is Van Den Hull Frog, phono stage is Sonic Frontiers Phono One.

Thank you.
