Thanks again, this is all amazing feedback. I know that the arm is even more critical than the table...and the cart even more critical.
My original thought for the first arm was the 4Point 9, but now I think I have more research to do. My plan was to upgrade from my first arm and move the first arm to the second position. I like the idea of a removable headshell for Mono or a second less expensive cart for scratchy records that I still love.
I was very curious about the Soundsmith Alto designed by Frank Schroder. Has anyone had experience with this arm?
