What is it about your system that you don't like ? The Dyna is still a great arm, so my feeling is that the limiting factor is the TT and perhaps the cartridge, not the arm. What type of music do you play ? You may want to look at the Avid TT's which I heard in Vegas some years ago. Myself I use a heavily modified Goldring GL75 after owning two Linn LP12's.
I couldn't be happier.
