That’s the stylus. The arm still has to move in x and y axis. Depends on the cartridge. A Jelco SA750 is an excellent inexpensive arm suited to lower compliance cartridges.
Best arm for a mono cartridge
Given that a mono cart has to move in one dimension and not two, is there an arm that you would recommend for this? I have a Phantom II with ZYX Airy 3 for my stereo but my Transrotor Fat Bob could take a second arm.
