I think you would get a better sonic improvement for your money by moving up to the Basis 2500 or 2800, and keeping the Rega arm. The RB900 is a very good arm, and although the Graham may be better, you get more improvement by upgrading the TT, than you do by upgrading the arm. The arm can only do what the TT will allow it to do. A 2800 TT will provide a better foundation for the arm to work with, and make a better overall sound with your Rega arm, than a Graham on your 2001 table.
