Upper end of cartridges for RB 250?
What is the upper end of cartridges for use with the RB 250 with Incognito wiring upgrade and Express Machino counter weight? I am looking for personnel knowledge from users or knowlegable professionals who have pushed this tonearm with similar upgrades. I am currently using the tonearm on a Basis 2001 into an Art Audio VP1 Mark II preamp with phono section. I am looking at possibly upgrading my phono preamp. Could the arm be used with a ZYX Airy 3, Miyabi or similar highend cartidges? I am looking for info on the cartidge compatibilty to the arm not the cartridge to the phono section. I deliberately left off the cartridge I am using now.
