Are you willing to buy used? If you are, and I see little danger in this if you buy from someone who has good feedback, then a Benz Ruby 2 is exceptionally good in the Graham. I have a 2.2 mounted on a VPI and I have used a number of cartridges, including the Shelter 501 II, in this arm. The Ruby is definitely the best of the bunch and I paid $800 for it. It does take a little courage to buy used but it is definitely worth considering.
Best cartridge under $800 for Graham 2.2
I have tried a Grado master and Orto Kont B. What are some other choices???? I have an Acoustic Signiture final tool. Mike
