Hello Marc, i have a Q for you as you seem to know a lot on Grado, I like the old early '80 A LOT! I now am playing with a F-3+ and prefer it over a Gold. I want to change the stylus to a 8mz. But i am seeing some complete NOS F-1+ carts online for sale. I know that there is a very fine nude tip on those but the suspension is 40 years old. The 8mz is bonded but the cantilever seems newer. Can you give your opinion?
